Master Art of Translation | The Mineral Exploration, Resource & Reserve Reporting Translation System — How JORC, CRIRSCO, NI 43-101, Grades, Categories and Technical Disclosures Keep Their Meaning

Why translating mineral resources and mining technical reports needs a reporting system, not just a dictionary

How do you translate a mining technical report accurately? How should a translator handle mineral resources, ore reserves, exploration results, drilling data, assay grades and the terminology of JORC, CRIRSCO or NI 43-101? A reader looking for mineral resource and reserve translation usually needs more than a bilingual mining glossary: the translation may be used to compare projects, interpret a public disclosure, review a feasibility study or understand the limits of an estimate. A small change in category, unit, cut-off grade or confidence can make an otherwise fluent sentence materially misleading.

Professional mining translation, geological report translation and technical translation for mineral exploration require a method that preserves the status of every claim. Exploration Targets are not Mineral Resources; Mineral Resources are not automatically Mineral Reserves; estimated contained metal is not the same thing as recoverable or saleable product; and a qualified professional’s responsibility cannot be recreated by polished prose. International reporting frameworks such as CRIRSCO-style codes give many of these terms specific roles, while reporting obligations and names vary across governing regimes.

This practical master guide shows how to translate mineral exploration and reserve reports, resource-estimation tables, mine-planning assumptions, assay certificates, recovery models, technical disclosures and investor-facing summaries without altering their meaning. It explains the hidden reporting problem, the mechanism beneath the vocabulary, a repeatable end-to-end translation workflow, failure patterns, worked fictional diagnostics and transfer exercises. Its purpose is accurate language mediation, not the certification of any mineral project, investment recommendation or substitute for professional geological and regulatory sign-off.

Architecture: EDKSG-TRANS-MASTER-WORLD-570. Scope: world-facing translation of mining and mineral-resource reporting; jurisdiction-specific terms and reporting duties are kept distinct rather than declared interchangeable. Status of examples: all numerical and project examples in the exercises below are invented solely to teach translation diagnosis.

This is a specialist child of Master Art of Translation | The Complete System for Moving Meaning Between Languages. The parent owns the general mechanism of translation; this article owns the mineral-reporting application. Readers building word knowledge can use the protected Vocabulary Learning Hub; readers analysing explanation, qualifications and evidence can consult the protected How English Works map. Those destinations are linked, not duplicated or modified.

The hidden problem: a mining report is a chain of claims with different levels of authority

The striking fact about a mineral report is that the same everyday noun can mean different things at different stages of a project. A resource is not a synonym for something merely found in the ground. A reserve is not a warehouse of metal waiting for shipment. A grade does not tell us the total amount of contained material unless we know tonnage and units. A recovery figure from laboratory testing does not necessarily predict the recovery achieved by a commercial operation. Readers need the boundaries between these propositions, not a story that runs smoothly across them.

The translator therefore carries several interconnected objects at once: the original scientific observation, its interpretation, the reporting classification, the named standard and edition, the date of the claim, the associated numeric table, the responsible person’s qualifications and consent, and the prospective use by a reader. If any object is separated from its qualifier, a risk may travel unnoticed into another language. This is why two translations with identical grammar can differ dramatically in evidential integrity.

Take the fictional phrase ‘an indicated resource of 12.0 Mt at 0.80% Cu above a 0.35% cut-off’. A careless target text may call it a ‘proven copper reserve of twelve million tonnes’. That seemingly small improvement destroys the confidence category, changes the resource/reserve distinction, drops the grade and cut-off conditions, and invites an inference of economic mineability not established by the source. No fluent paragraph can compensate for missing those constraints.

Standards provide a vocabulary, but not a universal licence to substitute labels. The Australian JORC Code, CRIRSCO’s International Reporting Template, Canadian CIM definitions used with NI 43-101, and US SEC Subpart 1300 share important international concepts yet impose their own detailed contexts. A translator checks the framework that the source actually invokes and preserves that identity. A document prepared under one regime must not emerge from translation claiming compliance with another.

The operational question is consequently not ‘Which dictionary word sounds closest?’ but ‘What would a competent reader be entitled to infer from this sentence after translation?’ If the answer differs from what the source supports, the translation is not ready. The review must follow numbers, tables, caveats, sign-offs, attachments and subsequent versions as well as sentences.

Mechanism: the twenty layers that keep a technical disclosure coherent

The point of this system is not that every reader must memorise a reporting code. It is that every reader can learn to ask the right type of question. Is this a measurement, a classification, an assumption, a model output, a decision, a prospective plan or an official approval? Once the type is clear, translation becomes a controlled movement between languages rather than a guessing game about which phrase looks most professional.

A report can be technically conservative and linguistically elegant at the same time. Good target-language prose does not exaggerate the claim; it makes the real claim easier to understand. The writer is free to change sentence order, replace awkward expressions and supply a concise explanation of a defined term, provided the explanation has not changed the evidence or authority in the source.

Context matters at every level: the word within the sentence, the sentence within the table, the table within the study, the study within the reporting code and the code within the disclosure environment. In practical terms, the translator’s working document should include the source passage, proposed rendering, concept ID, responsible data source, reason for the choice, reviewer note and final approval. That audit trail lets a later reader reconstruct what happened.

Some numbers are approximate, some are estimates with formal categories, and some are measurements with laboratory uncertainty. The same numeral may appear in all three settings. This article treats those settings separately so that numerical fidelity is not reduced to visually matching digits. In a complex translation, a number is correct only when its type, boundary and qualifier remain correct.

For investors, mining staff, translators and students alike, the most practical diagnostic is a three-column test: what did the source actually say, what might the target reader infer, and which supporting record warrants that inference? A mismatch between those columns is a translation defect even if all the nouns are dictionary-correct.

1. Reporting codes, editions and applicability

A technical disclosure inherits the definitions, qualification thresholds, disclosure obligations and date of the named reporting framework. The framework is metadata with legal and professional consequences, not ornamental background. A language change may explain a code, but it must not silently substitute a different code or imply cross-border acceptance.

What the translator must inspect. Identify code title, code edition, applicable regulator or listing rule, document date, original-language status and any reference to transitional provisions. Compare defined terms in the named authority rather than relying on a bilingual equivalence table compiled for another regime. This inspection should occur before choosing a target-language phrase, because the official concept and the actual evidence define the permitted wording. A plausible phrase that cannot be traced back to those materials is not a defensible substitute for a missing source record.

Why this mechanism travels. The habit is useful for safety regulations, accounting standards and clinical-study documentation: a source citation is part of meaning whenever a standard controls what claims can be made. The central test is whether the source reader and target reader are being asked to believe the same amount, with the same qualifications, about the same object at the same stage. When that symmetry breaks, the translation must be revised even when individual vocabulary choices seem natural.

2. Exploration targets and conceptual ranges

An Exploration Target communicates conceptual exploration potential, frequently as ranges, under conditions that prevent it from being mistaken for a Mineral Resource. The status of an exploration hypothesis must survive every translation, especially when headline writers want a single large number.

What the translator must inspect. Test whether the source asserts geological continuity, reasonable prospects of eventual economic extraction or merely a preliminary area of interest. Preserve ranges, units, conceptual status and qualifications of evidence. This inspection should occur before choosing a target-language phrase, because the official concept and the actual evidence define the permitted wording. A plausible phrase that cannot be traced back to those materials is not a defensible substitute for a missing source record.

Why this mechanism travels. The distinction also applies to research hypotheses, project forecasts and statistical confidence intervals: apparent precision is not the same as measured certainty. The central test is whether the source reader and target reader are being asked to believe the same amount, with the same qualifications, about the same object at the same stage. When that symmetry breaks, the translation must be revised even when individual vocabulary choices seem natural.

3. Exploration results, intersections and drilling language

Exploration Results are observations and interpretations from exploration work, not necessarily an inventory of economically mineable material. The translator must protect the boundary between reported sample intervals, geological widths, estimated true widths and selective highlights.

What the translator must inspect. Trace each interval from the drillhole name to from-to depths, length, grade, assay method and any statement on true thickness or orientation. Reproduce inclusive or exclusive endpoints as the actual source uses them. This inspection should occur before choosing a target-language phrase, because the official concept and the actual evidence define the permitted wording. A plausible phrase that cannot be traced back to those materials is not a defensible substitute for a missing source record.

Why this mechanism travels. The same chain-of-custody habit helps translate laboratory results, medical measurements and engineering tests whose meaning depends on a sampling location. The central test is whether the source reader and target reader are being asked to believe the same amount, with the same qualifications, about the same object at the same stage. When that symmetry breaks, the translation must be revised even when individual vocabulary choices seem natural.

4. Sampling, laboratories and data-quality evidence

Sample integrity is a property of the measurement process. Translated reports must distinguish field duplicates, blank samples, reference materials, laboratory repeats, detection limits, contaminants, missing data and rejected assays; these are not interchangeable quality-control labels.

What the translator must inspect. Map sample IDs, laboratory certificates, QA/QC thresholds, analytical methods, preparation methods and failure decisions to one stable naming convention. Keep failed checks visible in both narrative and tables. This inspection should occur before choosing a target-language phrase, because the official concept and the actual evidence define the permitted wording. A plausible phrase that cannot be traced back to those materials is not a defensible substitute for a missing source record.

Why this mechanism travels. For anyone translating testing or compliance documentation, the quality-control result and its limitations matter as much as the numerical measurement. The central test is whether the source reader and target reader are being asked to believe the same amount, with the same qualifications, about the same object at the same stage. When that symmetry breaks, the translation must be revised even when individual vocabulary choices seem natural.

5. Coordinates, spatial reference and mine geometry

A location in a geological table needs a coordinate reference system, datum, coordinate order and often vertical reference. Misleading conversions of eastings, northings, azimuths or metres can displace the apparent evidence or distort the size of a mineralised zone.

What the translator must inspect. Do not translate numeric coordinates into explanatory place names. Preserve identifiers, coordinate reference system metadata, decimal signs, orientation conventions and surveying status. This inspection should occur before choosing a target-language phrase, because the official concept and the actual evidence define the permitted wording. A plausible phrase that cannot be traced back to those materials is not a defensible substitute for a missing source record.

Why this mechanism travels. Spatial literacy carries into mapping, infrastructure asset translation and incident evidence: a coordinate without its frame is an incomplete location. The central test is whether the source reader and target reader are being asked to believe the same amount, with the same qualifications, about the same object at the same stage. When that symmetry breaks, the translation must be revised even when individual vocabulary choices seem natural.

6. Tonnage, volume, density and inventories

Tonnage is often a dry mass estimate derived partly from volume and density. A document that omits dry/wet basis, in-situ density, moisture and density-measurement method can generate numerical disagreements even when the digit sequence is copied perfectly.

What the translator must inspect. Record the mass basis, prefixes, rounding, density method and cut-off domain; compare every total with its component rows and flags for exclusions. This inspection should occur before choosing a target-language phrase, because the official concept and the actual evidence define the permitted wording. A plausible phrase that cannot be traced back to those materials is not a defensible substitute for a missing source record.

Why this mechanism travels. Density and mass-basis reasoning applies to shipping, agriculture and chemistry wherever wet mass, dry mass and volume are not equivalent. The central test is whether the source reader and target reader are being asked to believe the same amount, with the same qualifications, about the same object at the same stage. When that symmetry breaks, the translation must be revised even when individual vocabulary choices seem natural.

7. Grade units, contained metal and reporting bases

Grade, tonnage and contained material must be read together. Percent, grams per tonne, parts per million, ounces and pounds are not freely interchangeable labels, and conversions require attention to measurement basis, product type and rounding.

What the translator must inspect. Freeze each physical unit with the number it qualifies. Keep grade, content and recoverable metal separate and reconcile only after verifying the source’s mass units and commodity conventions. This inspection should occur before choosing a target-language phrase, because the official concept and the actual evidence define the permitted wording. A plausible phrase that cannot be traced back to those materials is not a defensible substitute for a missing source record.

Why this mechanism travels. The same discipline prevents medicine-dose, chemical-concentration and financial-unit mistakes across languages. The central test is whether the source reader and target reader are being asked to believe the same amount, with the same qualifications, about the same object at the same stage. When that symmetry breaks, the translation must be revised even when individual vocabulary choices seem natural.

8. Cut-off grade, domains and estimation boundaries

A cut-off grade is a conditional reporting threshold, not an assay grade, a production target or an intrinsic property of every block. Classification and tonnage can change when cut-off assumptions change, so the denominator and reporting scenario matter.

What the translator must inspect. Capture cut-off value, unit, conceptual economic basis, reporting date and selected geological domain. A different cut-off must be presented as a separate scenario, not merged with the base case. This inspection should occur before choosing a target-language phrase, because the official concept and the actual evidence define the permitted wording. A plausible phrase that cannot be traced back to those materials is not a defensible substitute for a missing source record.

Why this mechanism travels. Conditional reporting thresholds appear in environmental monitoring and finance; the translated condition is part of the claim. The central test is whether the source reader and target reader are being asked to believe the same amount, with the same qualifications, about the same object at the same stage. When that symmetry breaks, the translation must be revised even when individual vocabulary choices seem natural.

9. Mineral Resource confidence categories

Inferred, Indicated and Measured are defined classifications tied to geological knowledge and confidence, not promotional adjectives. The categories cannot be treated as interchangeable proof of the same degree of certainty.

What the translator must inspect. Check the exact capitalization, classification criteria, uncertainty statement and whether figures are broken out by category. Never translate confidence categories into ordinary-language certainty claims. This inspection should occur before choosing a target-language phrase, because the official concept and the actual evidence define the permitted wording. A plausible phrase that cannot be traced back to those materials is not a defensible substitute for a missing source record.

Why this mechanism travels. Defined classifications require a concept-first glossary, just as grading systems and clinical evidence classifications do. The central test is whether the source reader and target reader are being asked to believe the same amount, with the same qualifications, about the same object at the same stage. When that symmetry breaks, the translation must be revised even when individual vocabulary choices seem natural.

10. Mineral Reserve declaration and modifying factors

Mineral Reserves add considerations beyond geological confidence, including mining, processing, metallurgical, economic, marketing, legal, environmental, social and governmental factors. The translator cannot convert a resource to a reserve by changing a noun.

What the translator must inspect. Trace the parent resource category, reserve study, modifying factors, professional responsibility and distinction between Proved and Probable categories under the governing code. This inspection should occur before choosing a target-language phrase, because the official concept and the actual evidence define the permitted wording. A plausible phrase that cannot be traced back to those materials is not a defensible substitute for a missing source record.

Why this mechanism travels. A determination based on several dependencies cannot be restated as a direct observation; the same logic holds for certification decisions. The central test is whether the source reader and target reader are being asked to believe the same amount, with the same qualifications, about the same object at the same stage. When that symmetry breaks, the translation must be revised even when individual vocabulary choices seem natural.

11. Mining methods, dilution and recovery

Mine plans distinguish ore scheduled for extraction, dilution added during mining, mining recovery, metallurgical recovery, loss and saleable product. A single generic word ‘yield’ erases distinctions that control both technical and economic calculations.

What the translator must inspect. Follow the material balance from modelled resource to reserve, mined ore, processed feed, concentrate and saleable product. Keep each percentage attached to its stage. This inspection should occur before choosing a target-language phrase, because the official concept and the actual evidence define the permitted wording. A plausible phrase that cannot be traced back to those materials is not a defensible substitute for a missing source record.

Why this mechanism travels. Flow diagrams are translation aids whenever terms mark different transformations in a process rather than synonyms. The central test is whether the source reader and target reader are being asked to believe the same amount, with the same qualifications, about the same object at the same stage. When that symmetry breaks, the translation must be revised even when individual vocabulary choices seem natural.

12. Metallurgy, processing and product specifications

Metallurgical testing describes how a particular sample behaved in specified conditions. Bench-scale recovery, plant design recovery, concentrate grade and impurities refer to different outcomes and cannot be conflated.

What the translator must inspect. Track sample representativeness, test scale, process stage, metal deportment, recovery basis, payable product assumptions and whether a figure is achieved, designed or forecast. This inspection should occur before choosing a target-language phrase, because the official concept and the actual evidence define the permitted wording. A plausible phrase that cannot be traced back to those materials is not a defensible substitute for a missing source record.

Why this mechanism travels. Evidence levels in trials and prototypes are not automatically operational performance; translators must preserve the scale of demonstration. The central test is whether the source reader and target reader are being asked to believe the same amount, with the same qualifications, about the same object at the same stage. When that symmetry breaks, the translation must be revised even when individual vocabulary choices seem natural.

13. Economics, studies and financial sensitivity

Study labels and economic outputs are conditional. Scoping or preliminary economic analyses, pre-feasibility and feasibility studies are not synonyms. NPV, IRR, payback, discount rate, tax basis, price assumptions and confidence must stay attached to their assumptions and purpose.

What the translator must inspect. Preserve the study stage, base case, commodity price units, currency, date, real/nominal terms, discount-rate basis, contingency and project status. Never state conditional financial outputs as guaranteed returns. This inspection should occur before choosing a target-language phrase, because the official concept and the actual evidence define the permitted wording. A plausible phrase that cannot be traced back to those materials is not a defensible substitute for a missing source record.

Why this mechanism travels. The translation mechanism also applies to forecasts, budgets and appraisals where a scenario is not a promise. The central test is whether the source reader and target reader are being asked to believe the same amount, with the same qualifications, about the same object at the same stage. When that symmetry breaks, the translation must be revised even when individual vocabulary choices seem natural.

14. Geotechnical, groundwater and operational constraints

Slope design, ground support, water inflow and material handling can change the practical extraction envelope. A translated report must not confuse a design parameter with a measured universal condition or smooth away the need for further investigation.

What the translator must inspect. Keep angle reference, units, hydrogeological model status, contingency assumptions and named location-specific constraints only as technical properties, never as promotional certainty. This inspection should occur before choosing a target-language phrase, because the official concept and the actual evidence define the permitted wording. A plausible phrase that cannot be traced back to those materials is not a defensible substitute for a missing source record.

Why this mechanism travels. When engineering design contains provisional limits, these qualifiers must be preserved in translation to prevent unsafe action. The central test is whether the source reader and target reader are being asked to believe the same amount, with the same qualifications, about the same object at the same stage. When that symmetry breaks, the translation must be revised even when individual vocabulary choices seem natural.

15. Permits, environmental effects and rehabilitation

A permit application, conditional approval, issued permit and completed compliance action are different statuses. Translators must keep environmental baseline data, mitigation commitments, closure obligations and rehabilitation provisions distinct.

What the translator must inspect. Check the issuing authority, permit identifier, effective period, conditions, monitoring obligations, protected areas and conditions precedent. Do not invent consent from a project timetable. This inspection should occur before choosing a target-language phrase, because the official concept and the actual evidence define the permitted wording. A plausible phrase that cannot be traced back to those materials is not a defensible substitute for a missing source record.

Why this mechanism travels. Permit-state fidelity matters in construction, pharmaceuticals and public administration as much as in mining. The central test is whether the source reader and target reader are being asked to believe the same amount, with the same qualifications, about the same object at the same stage. When that symmetry breaks, the translation must be revised even when individual vocabulary choices seem natural.

16. Community, land access and governance

Public reporting often refers to consultation, agreements, access rights, cultural-heritage restrictions and community grievances. A translator must not turn engagement into consent, a proposal into a binding agreement, or a reported absence of complaints into proof of acceptance.

What the translator must inspect. Identify who spoke, on behalf of whom, the procedural status, relevant document, evidence of authorization and any outstanding issue. Use neutral terminology rather than imposing the language of a different legal system. This inspection should occur before choosing a target-language phrase, because the official concept and the actual evidence define the permitted wording. A plausible phrase that cannot be traced back to those materials is not a defensible substitute for a missing source record.

Why this mechanism travels. The method applies to humanitarian communication and contract translation: social legitimacy cannot be manufactured by paraphrase. The central test is whether the source reader and target reader are being asked to believe the same amount, with the same qualifications, about the same object at the same stage. When that symmetry breaks, the translation must be revised even when individual vocabulary choices seem natural.

17. Competent Persons, Qualified Persons and accountability

Competent Person and Qualified Person are regulated professional terms whose exact role depends on the controlling framework. A translator may explain a role but cannot create authorship, independence, registration or consent the source does not demonstrate.

What the translator must inspect. Keep the person’s name, qualification, professional-body membership, area of responsibility, consent language, signature date and conflicts separately traceable. Check whether the individual reviewed the translated text. This inspection should occur before choosing a target-language phrase, because the official concept and the actual evidence define the permitted wording. A plausible phrase that cannot be traced back to those materials is not a defensible substitute for a missing source record.

Why this mechanism travels. Attribution and sign-off literacy is central to clinical, legal and academic translation: a language service is not the original expert’s certification. The central test is whether the source reader and target reader are being asked to believe the same amount, with the same qualifications, about the same object at the same stage. When that symmetry breaks, the translation must be revised even when individual vocabulary choices seem natural.

18. Versions, effective dates and superseded claims

A resource statement is a dated estimate. A later technical study, depleted inventory, revised interpretation or corrected assay batch can change its scope. Translating the newest-sounding number without keeping date and status can create a false time series.

What the translator must inspect. Separate issue date, effective date of estimates, data cutoff, audit date, signature date and amendment date. Build a revision map before cross-referencing numbers. This inspection should occur before choosing a target-language phrase, because the official concept and the actual evidence define the permitted wording. A plausible phrase that cannot be traced back to those materials is not a defensible substitute for a missing source record.

Why this mechanism travels. Version control is essential whenever evolving evidence changes a claim, from legislation and public health to engineering and scientific publishing. The central test is whether the source reader and target reader are being asked to believe the same amount, with the same qualifications, about the same object at the same stage. When that symmetry breaks, the translation must be revised even when individual vocabulary choices seem natural.

19. Commodity-specific products and critical-mineral reporting

Mining projects report different measures for different commodities: concentrate, equivalent grade, recoverable product, lithium carbonate equivalent, rare-earth oxides and marketable materials. A commodity label is not always a pure-element mass.

What the translator must inspect. Define the exact product, chemical form, conversion factor, payable content and reporting purpose. Keep material available for sale separate from conceptual contained quantity. This inspection should occur before choosing a target-language phrase, because the official concept and the actual evidence define the permitted wording. A plausible phrase that cannot be traced back to those materials is not a defensible substitute for a missing source record.

Why this mechanism travels. Chemical-species and product-form distinctions also matter in energy storage, pharmacology, food science and environmental reporting. The central test is whether the source reader and target reader are being asked to believe the same amount, with the same qualifications, about the same object at the same stage. When that symmetry breaks, the translation must be revised even when individual vocabulary choices seem natural.

20. Tables, graphics, translations and digital lineage

The text of a mining report is distributed across prose, figures, tables, attachments, spatial files and spreadsheets. Formatting and machine processing can alter numbers, labels, footnotes and links; translating only sentences fails to maintain the data relationships.

What the translator must inspect. Treat captions, headers, figures, units, formula cells, references, alt text and annexes as a single controlled evidence set. Use bilingual change logs and validation reports at every export boundary. This inspection should occur before choosing a target-language phrase, because the official concept and the actual evidence define the permitted wording. A plausible phrase that cannot be traced back to those materials is not a defensible substitute for a missing source record.

Why this mechanism travels. The transferable principle is data lineage: meaning lives in relationships among values, schema, provenance and human explanations. The central test is whether the source reader and target reader are being asked to believe the same amount, with the same qualifications, about the same object at the same stage. When that symmetry breaks, the translation must be revised even when individual vocabulary choices seem natural.

Repeatable method: fifteen quality gates from intake to release

The following gates are a working sequence, not a substitute for technical review. They are designed for real translation projects involving source-language documents, spreadsheets, figures, professional attestations and public-facing summaries. Apply every gate to high-consequence passages, and scale the level of documentation to the use and risk of the material.

Gate 01 — Freeze the claim inventory

Extract every affirmative, conditional and negative claim; identify its intended reader and use. Link a claim to the report section, figure, table and publication status. The practical output is a versioned claim ledger rather than a free-floating glossary.

A usable completion record for this gate states source (which page, table, database field or external standard supports the decision), target (what wording or numerical representation was released), reviewer (who checked the factual meaning), and exception (what remains unresolved). A reviewer should be able to reverse the path from target-language text to the controlling source without guessing. If that is impossible, the gate is incomplete and the relevant passage needs a traceable correction.

Gate 02 — Name the governing vocabulary

Write down the standard and edition used by the source. Create one concept record per defined term, with definition, context, permitted target-language rendering and prohibited near-synonyms. Record where official definitions diverge across frameworks.

Gate 03 — Record professional responsibility

Identify the author, Competent Person or Qualified Person, sections of responsibility and original consent. Never assume that a translator’s fidelity audit creates a new technical sign-off or replaces regulatory approvals.

Gate 04 — Separate observations from interpretations

Mark raw assays, drilling intersections, modelled domains, inferred continuity, resource estimates, reserve studies and project forecasts. A translator should be able to explain why each sentence belongs to one evidentiary layer.

Gate 05 — Build the units ledger

List every quantitative unit, prefix, dry/wet basis, chemical form, currency, price unit, cut-off condition, density and percentage. Give each number a semantic type; values copied correctly into the wrong type can still be dangerous.

Gate 06 — Lock classifications before drafting

Record Inferred, Indicated, Measured, Probable and Proved/Proven exactly as the source code uses them. Maintain separate category rows. Do not let editorial fluency collapse them into one confident-sounding inventory.

Gate 07 — Map formulas and dependencies

When a report uses equivalents, contained-metal calculations, net-smelter-return estimates or discounted values, locate the formula and inputs. Preserve variables and assumptions rather than rewriting derived outputs as observations.

Gate 08 — Tag provisionality and scope

Highlight ‘may’, ‘subject to’, ‘expected’, ‘preliminary’, ‘not included’, ‘pending’, ‘at the date of’ and other qualification markers. These small words often carry the largest difference between useful information and overstatement.

Gate 09 — Translate the full document object

Include tables, maps, captions, legends, appendices, embedded spreadsheets, alt descriptions and file names. Mark each artefact as translated, preserved unchanged, reproduced with annotation or excluded with an explicit explanation.

Gate 10 — Run a bilingual technical review

Ask a geoscience or mining-domain reviewer to compare technical meaning against the source. Ask a qualified language reviewer to assess the target-language readability. The two reviews solve different problems.

Gate 11 — Reconcile numeric tables

Use row-level source-target checks for values, unit conversions, categories, totals, footnotes and signs. Verify that any recalculated figure is authorized and documented; never silently replace an official source value because arithmetic looks cleaner.

Gate 12 — Audit jurisdiction and edition

Before publication, refresh official source pages for relevant codes and regulator guidance. Changes to draft status or adopted editions should be recorded in a dated research note and never silently inserted into the translation of a historical document.

Gate 13 — Carry uncertainty forward

Check whether the translation preserves confidence level, scope, sampling limits, assumptions, missing tests, prospective exploration and all ‘not yet’ conditions. Ask whether a cautious reader would reach the same cautious conclusion in both languages.

Gate 14 — Control machine translation and AI

Treat machine-generated text as a proposal, not evidence. Resolve hallucinated defined terms, altered numbers, flipped negations, lost table footnotes and invented approvals through human source comparison. Record whether the full post-editing workflow is suitable for the risk.

Gate 15 — Verify release and handoff

Final checks include target-language style, working links, register of changed tables, approval to publish, provenance, dated source inventory and correction pathway. Release only the same set of claims the accountable source supports.

Failure modes: twenty-eight ways a fluent translation can change the evidence

These failure modes are distinct because each changes a different logical relationship. An effective quality check identifies not just a misspelling but the particular inferential jump that the error would invite. For each example, imagine that the translated sentence is reused in a presentation, report summary or database export: the error may become more consequential after the original footnotes are no longer visible.

Failure 01: Claim inflation

The failure occurs when the translation is Converting an exploration possibility into a reportable estimate. A reader may then interpret a statement of limited scope as a broader finding, or may act on a value or permission that the source never asserted. Check verbs, defined categories and caveats; demand a source-authorised classification before accepting any stronger claim.

The diagnostic is to identify the smallest source unit that carries the disputed meaning, then reconstruct its links to the classification table, calculation, footnote, professional statement or relevant rule. Review the final rendered page, not only the text editor, because this sort of failure often appears when headings are shortened, charts are rebuilt or source-language qualifiers disappear during layout. The safe outcome is a corrected target proposition with the original boundary preserved, followed by a logged reason for the change.

Failure 02: Category migration

The failure occurs when the translation is Replacing Inferred, Indicated or Measured with a confident-sounding adjective. A reader may then interpret a statement of limited scope as a broader finding, or may act on a value or permission that the source never asserted. Retain the correct technical category throughout headline, figures, abstract and tables.

Failure 03: Resource/reserve substitution

The failure occurs when the translation is Calling a Mineral Resource an Ore Reserve or the converse. A reader may then interpret a statement of limited scope as a broader finding, or may act on a value or permission that the source never asserted. Demand evidence of modifying factors and a separate compliant reserve declaration.

Failure 04: Unit substitution

The failure occurs when the translation is Switching g/t, %, ppm, t, kt and Mt as if they were surface labels. A reader may then interpret a statement of limited scope as a broader finding, or may act on a value or permission that the source never asserted. Freeze numeric-type pairs and use independent conversion checks.

Failure 05: Chemical-form confusion

The failure occurs when the translation is Calling oxide equivalent the pure metal content. A reader may then interpret a statement of limited scope as a broader finding, or may act on a value or permission that the source never asserted. Confirm chemical formula, equivalent factor and purpose of the reported product.

Failure 06: False recovery

The failure occurs when the translation is Treating contained metal as forecast recovery or saleable production. A reader may then interpret a statement of limited scope as a broader finding, or may act on a value or permission that the source never asserted. Follow material flow and separately record mining, processing, refining and payable assumptions.

Failure 07: Omitted cut-off

The failure occurs when the translation is Dropping a reporting threshold from the translated figure. A reader may then interpret a statement of limited scope as a broader finding, or may act on a value or permission that the source never asserted. Attach cut-off to the quantity and preserve sensitivity notes.

Failure 08: Headline cherry-picking

The failure occurs when the translation is Moving the highest interval grade into the deposit average. A reader may then interpret a statement of limited scope as a broader finding, or may act on a value or permission that the source never asserted. Cross-check weighted composites and the scope of the advertised interval.

Failure 09: True-width invention

The failure occurs when the translation is Rewording downhole metres as true geological thickness. A reader may then interpret a statement of limited scope as a broader finding, or may act on a value or permission that the source never asserted. Preserve measured length and orientation uncertainty.

Failure 10: Authority swap

The failure occurs when the translation is Replacing code names, regulator names or professional titles. A reader may then interpret a statement of limited scope as a broader finding, or may act on a value or permission that the source never asserted. Preserve formal identifiers and add explanations without implying compliance with a different regime.

Failure 11: Draft adoption

The failure occurs when the translation is Presenting a consultation proposal as an adopted requirement. A reader may then interpret a statement of limited scope as a broader finding, or may act on a value or permission that the source never asserted. Verify adoption, effective dates and transition rules on the authority’s page.

Failure 12: Scope inversion

The failure occurs when the translation is Turning a limited resource shell into an entire licence estimate. A reader may then interpret a statement of limited scope as a broader finding, or may act on a value or permission that the source never asserted. Check boundary, project name, zone and model extraction.

Failure 13: Missing sign-off

The failure occurs when the translation is Ascribing the translated text to a professional who did not approve it. A reader may then interpret a statement of limited scope as a broader finding, or may act on a value or permission that the source never asserted. Keep the exact responsibility and consent context distinct from translation quality review.

Failure 14: Status laundering

The failure occurs when the translation is Translating submitted or pending as permitted or completed. A reader may then interpret a statement of limited scope as a broader finding, or may act on a value or permission that the source never asserted. Compare application, grant, conditions and obligations separately.

Failure 15: Omitted uncertainty

The failure occurs when the translation is Removing may, could, preliminary, conditional or not established. A reader may then interpret a statement of limited scope as a broader finding, or may act on a value or permission that the source never asserted. Reconstruct the proposition’s strength and ensure it stays unchanged.

Failure 16: Data-lineage loss

The failure occurs when the translation is Separating a value from its footnote, model version or assay method. A reader may then interpret a statement of limited scope as a broader finding, or may act on a value or permission that the source never asserted. Give every output an identifiable source, table and revision.

Failure 17: Graphical misleadingness

The failure occurs when the translation is Changing figure legends or colour labels while preserving prose. A reader may then interpret a statement of limited scope as a broader finding, or may act on a value or permission that the source never asserted. Review map and chart semantics alongside the text.

Failure 18: Table truncation

The failure occurs when the translation is Dropping rows of low-confidence resources or negative results. A reader may then interpret a statement of limited scope as a broader finding, or may act on a value or permission that the source never asserted. Perform table-by-table and record-level reconciliation.

Failure 19: Numeric locale damage

The failure occurs when the translation is Converting decimal separators and CSV delimiters incorrectly. A reader may then interpret a statement of limited scope as a broader finding, or may act on a value or permission that the source never asserted. Test numeric fields after export, not only in the editor preview.

Failure 20: Rounding invention

The failure occurs when the translation is Changing published totals to force exact sums. A reader may then interpret a statement of limited scope as a broader finding, or may act on a value or permission that the source never asserted. Consult rounding policies and do not alter approved published estimates unilaterally.

Failure 21: Geographic overclaim

The failure occurs when the translation is Treating a local mine datum as geodetic or mean sea level. A reader may then interpret a statement of limited scope as a broader finding, or may act on a value or permission that the source never asserted. Verify coordinate reference metadata before changing notation.

Failure 22: Financial guarantee

The failure occurs when the translation is Turning NPV or projected IRR into promised income. A reader may then interpret a statement of limited scope as a broader finding, or may act on a value or permission that the source never asserted. Retain discount rates, scenarios, sensitivity and forecast status.

Failure 23: Environmental greenwashing

The failure occurs when the translation is Translating a mitigation intention as achieved compliance. A reader may then interpret a statement of limited scope as a broader finding, or may act on a value or permission that the source never asserted. Preserve monitoring evidence, timing and permit conditions.

Failure 24: Community-consent overclaim

The failure occurs when the translation is Treating attendance at consultation as an agreement. A reader may then interpret a statement of limited scope as a broader finding, or may act on a value or permission that the source never asserted. Require a documented outcome before changing action status.

Failure 25: Outdated estimate stacking

The failure occurs when the translation is Adding superseded figures to a new resource statement. A reader may then interpret a statement of limited scope as a broader finding, or may act on a value or permission that the source never asserted. Read the history as successive estimates, never independent deposits.

Failure 26: Unqualified equivalence

The failure occurs when the translation is Mapping a regulatory term to an appealing target-language near-synonym. A reader may then interpret a statement of limited scope as a broader finding, or may act on a value or permission that the source never asserted. Use a bilingual concept card and a note where legal equivalence cannot be guaranteed.

Failure 27: Machine-translation hallucination

The failure occurs when the translation is Letting a model invent professional names, source citations or legal approval. A reader may then interpret a statement of limited scope as a broader finding, or may act on a value or permission that the source never asserted. Compare every proper noun and claim with the source record and reject unsupported additions.

Failure 28: Investor-friendly smoothing

The failure occurs when the translation is Removing material caveats for clarity or sales appeal. A reader may then interpret a statement of limited scope as a broader finding, or may act on a value or permission that the source never asserted. Keep necessary uncertainty in the reader-facing summary even when it makes the prose longer.

Worked translation diagnostics: eighty source-to-target cases across twenty domains

All examples that follow are invented. They demonstrate what a translator should preserve and what a reviewer should check; they do not describe an actual mine, certified estimate or investment. The ‘misleading’ wording is deliberately wrong. Accurate translation into any target language must preserve the stated idea, not simply copy the suggested English sentence. Each case includes a failure mechanism, documentary evidence route and transfer test so the reader can practise resolving a new example rather than memorising a single answer.

Diagnostic cluster 1: Reporting codes, editions and applicability

In this cluster, the controlling principle is the following: A technical disclosure inherits the definitions, qualification thresholds, disclosure obligations and date of the named reporting framework. The framework is metadata with legal and professional consequences, not ornamental background. A language change may explain a code, but it must not silently substitute a different code or imply cross-border acceptance. The case is complete only when the classification, scope, evidence level and status of the assertion are mutually consistent across every language. In the field, the reviewer should read the nearest table or diagram and examine what the sentence does not claim as carefully as what it does claim.

Worked case 01: A cited edition

Source passage: Prepared in accordance with the JORC Code, 2012 Edition. Misleading translation: Prepared in accordance with the JORC 2026 Code. Meaning-preserving rendering: Prepared with reference to the JORC Code, 2012 Edition, exactly as cited in the source. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Changing a dated reference to a newer-sounding edition fabricates compliance with a text the author did not invoke. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Verify the title page, definitions section, release date and official JORC code-update page. As of the reviewed August 2026 update, treat the code review as a review rather than assuming a new edition is effective. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

A repeatable edit sequence: First isolate the controlling noun or number from the source. Next mark its domain, qualifier, time and conditional basis. Then compare the proposed target phrase against the formal concept used elsewhere in the document. Finally read the phrase in the sentence and the sentence in its table or figure context. In this case, the safe check is guided by Identify code title, code edition, applicable regulator or listing rule, document date, original-language status and any reference to transitional provisions. Compare defined terms in the named authority rather than relying on a bilingual equivalence table compiled for another regime. It is the linked set of checks, rather than a single dictionary lookup, that protects the reader.

What goes wrong downstream? A summary writer may reuse the misleading version without its original footnotes, making the assertion sound more certain or more general than it was. A data manager may carry the same mistranslation into a spreadsheet heading, where it appears credible because the number has not changed. A third-party reader might then compare unlike quantities or authorisations. Prevention means releasing the correction in every linked place: executive summary, body, table, caption, glossary and machine-readable output, where those places exist.

Transfer test: Ask another reviewer to explain, without seeing the original drafting notes, what the source does and does not establish. Ask them to point to the evidence they would use to validate the conclusion. Then give them the misleading rendering and have them identify its extra assumption. If they cannot distinguish the two readings, the teaching note or translated qualifier is still insufficient. The habit is useful for safety regulations, accounting standards and clinical-study documentation: a source citation is part of meaning whenever a standard controls what claims can be made. This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 02: Cross-border branding

Source passage: The assessment uses CIM Definition Standards adopted May 2014. Misleading translation: This is a JORC-certified resource estimate. Meaning-preserving rendering: The assessment uses the CIM Definition Standards identified by the source, with no added claim of JORC certification. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? The definitions may be comparable in spirit without creating compliance or independent certification. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Check the disclosed technical report’s reporting framework, the Canadian standards page and every occurrence of ‘qualified person’ or ‘competent person’. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

Worked case 03: Draft versus adopted text

Source passage: The team discussed proposed changes in a consultation draft. Misleading translation: The mandatory new requirements now apply. Meaning-preserving rendering: The team discussed proposed changes; the source does not state that they have been adopted. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? A draft is a possible future rule, not an existing obligation. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Locate the proposal, consultation dates, authority’s adoption statement and any effective-date provision; require confirmation of actual adoption before changing regulatory verbs. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

Worked case 04: Scope of public reporting

Source passage: The internal study has not been released as a public mineral-resource report. Misleading translation: The company publicly confirmed the resource estimate. Meaning-preserving rendering: The document describes an internal study and expressly says it is not a public mineral-resource report. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Converting an internal assessment into public disclosure changes the reader’s expectations about professional responsibility. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Compare the report distribution statement, version-control sheet, disclosure permissions and any source sentence restricting quotation. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

Diagnostic cluster 2: Exploration targets and conceptual ranges

In this cluster, the controlling principle is the following: An Exploration Target communicates conceptual exploration potential, frequently as ranges, under conditions that prevent it from being mistaken for a Mineral Resource. The status of an exploration hypothesis must survive every translation, especially when headline writers want a single large number. The case is complete only when the classification, scope, evidence level and status of the assertion are mutually consistent across every language. In the field, the reviewer should read the nearest table or diagram and examine what the sentence does not claim as carefully as what it does claim.

Worked case 05: Conceptual tonnage

Source passage: The exploration target ranges from 8 to 15 Mt, with insufficient work to estimate a Mineral Resource. Misleading translation: The property contains 15 Mt of confirmed resources. Meaning-preserving rendering: The conceptual exploration target is 8–15 Mt; the work completed is insufficient to estimate a Mineral Resource. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Choosing the upper endpoint and changing ‘target’ to ‘resource’ turns a possible range into asserted inventory. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Check maps, drill coverage, range derivation, the cautionary statement and whether the source uses an expressly defined Exploration Target. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

A repeatable edit sequence: First isolate the controlling noun or number from the source. Next mark its domain, qualifier, time and conditional basis. Then compare the proposed target phrase against the formal concept used elsewhere in the document. Finally read the phrase in the sentence and the sentence in its table or figure context. In this case, the safe check is guided by Test whether the source asserts geological continuity, reasonable prospects of eventual economic extraction or merely a preliminary area of interest. Preserve ranges, units, conceptual status and qualifications of evidence. It is the linked set of checks, rather than a single dictionary lookup, that protects the reader.

Transfer test: Ask another reviewer to explain, without seeing the original drafting notes, what the source does and does not establish. Ask them to point to the evidence they would use to validate the conclusion. Then give them the misleading rendering and have them identify its extra assumption. If they cannot distinguish the two readings, the teaching note or translated qualifier is still insufficient. The distinction also applies to research hypotheses, project forecasts and statistical confidence intervals: apparent precision is not the same as measured certainty. This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 06: Target grade range

Source passage: The conceptual target is 0.6–1.1% Cu, subject to further drilling. Misleading translation: The copper grade is 1.1% and is established. Meaning-preserving rendering: The target grade is expressed as a conceptual 0.6–1.1% copper range subject to further drilling. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? The high end is not the average, and a conceptual range is not an assay-certified property-wide result. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Inspect the supporting sampling basis, coverage limitations, assay intervals and planned drilling programme. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

A repeatable edit sequence: First isolate the controlling noun or number from the source. Next mark its domain, qualifier, time and conditional basis. Then compare the proposed target phrase against the formal concept used elsewhere in the document. Finally read the phrase in the sentence and the sentence in its table or figure context. In this case, the safe check is guided by Test whether the source asserts geological continuity, reasonable prospects of eventual economic extraction or merely a preliminary area of interest.

Ask them to point to the evidence they would use to validate the conclusion. Then give them the misleading rendering and have them identify its extra assumption. If they cannot distinguish the two readings, the teaching note or translated qualifier is still insufficient. The distinction also applies to research hypotheses, project forecasts and statistical confidence intervals: apparent precision is not the same as measured certainty. This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 07: No geological guarantee

Source passage: The structure may continue beneath the cover sequence. Misleading translation: The orebody extends under the overburden. Meaning-preserving rendering: The structure may continue beneath the cover sequence; continuity has not been established. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Replacing a modal possibility with a finding creates apparent geological knowledge that the evidence does not establish. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Locate the interpreted cross-section, blind target assumptions and any indication that drilling has not tested the zone. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

A repeatable edit sequence: First isolate the controlling noun or number from the source. Next mark its domain, qualifier, time and conditional basis.

The distinction also applies to research hypotheses, project forecasts and statistical confidence intervals: apparent precision is not the same as measured certainty. This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 08: Resource not declared

Source passage: The announcement does not report a Mineral Resource for the prospect. Misleading translation: The prospect reports its first reserve. Meaning-preserving rendering: No Mineral Resource has been reported for the prospect in this announcement. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? A null disclosure cannot be translated into an affirmative classification. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Cross-check the summary, classification table and dated public releases; absence of classification must remain absence, not an inferred zero. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

A repeatable edit sequence: First isolate the controlling noun or number from the source. Next mark its domain, qualifier, time and conditional basis.

The distinction also applies to research hypotheses, project forecasts and statistical confidence intervals: apparent precision is not the same as measured certainty. This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Diagnostic cluster 3: Exploration results, intersections and drilling language

In this cluster, the controlling principle is the following: Exploration Results are observations and interpretations from exploration work, not necessarily an inventory of economically mineable material. The translator must protect the boundary between reported sample intervals, geological widths, estimated true widths and selective highlights. The case is complete only when the classification, scope, evidence level and status of the assertion are mutually consistent across every language. In the field, the reviewer should read the nearest table or diagram and examine what the sentence does not claim as carefully as what it does claim.

Worked case 09: Downhole interval

Source passage: Hole AX-04 intersected 18 m from 122 m downhole at 1.2 g/t Au. Misleading translation: An 18 m thick gold vein was found at 122 m depth. Meaning-preserving rendering: Hole AX-04 returned an 18 m downhole intercept beginning at 122 m at 1.2 g/t gold; true width is not inferred. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Drilled length can differ materially from true perpendicular thickness. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Check collar coordinates, hole angle, assay composite, section geometry and source notes on true widths. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

A repeatable edit sequence: First isolate the controlling noun or number from the source. Next mark its domain, qualifier, time and conditional basis. Then compare the proposed target phrase against the formal concept used elsewhere in the document. Finally read the phrase in the sentence and the sentence in its table or figure context. In this case, the safe check is guided by Trace each interval from the drillhole name to from-to depths, length, grade, assay method and any statement on true thickness or orientation. Reproduce inclusive or exclusive endpoints as the actual source uses them. It is the linked set of checks, rather than a single dictionary lookup, that protects the reader.

Transfer test: Ask another reviewer to explain, without seeing the original drafting notes, what the source does and does not establish. Ask them to point to the evidence they would use to validate the conclusion. Then give them the misleading rendering and have them identify its extra assumption. If they cannot distinguish the two readings, the teaching note or translated qualifier is still insufficient. The same chain-of-custody habit helps translate laboratory results, medical measurements and engineering tests whose meaning depends on a sampling location. This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 10: Included high grade

Source passage: Twenty metres at 0.9% Cu, including 3 m at 2.7% Cu. Misleading translation: Twenty-three metres at 3.6% copper. Meaning-preserving rendering: A 20 m intercept averaging 0.9% copper, including a 3 m higher-grade interval averaging 2.7% copper. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? An included interval is part of the total and cannot be added as an extra length or grade. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Compare the assay interval table, nested compositing convention and weighted-average calculation. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

A repeatable edit sequence: First isolate the controlling noun or number from the source. Next mark its domain, qualifier, time and conditional basis. Then compare the proposed target phrase against the formal concept used elsewhere in the document. Finally read the phrase in the sentence and the sentence in its table or figure context. In this case, the safe check is guided by Trace each interval from the drillhole name to from-to depths, length, grade, assay method and any statement on true thickness or orientation.

The same chain-of-custody habit helps translate laboratory results, medical measurements and engineering tests whose meaning depends on a sampling location. This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 11: Trench versus drill

Source passage: Surface trench T-7 exposed 6 m of mineralised rock. Misleading translation: A six-metre drillhole confirmed underground ore. Meaning-preserving rendering: Trench T-7 exposed a six-metre surface interval of mineralised rock. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? The observation method limits the inference about depth and continuity. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Read the field method, sampling map and trench depth rather than inventing drillhole evidence. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

A repeatable edit sequence: First isolate the controlling noun or number from the source. Next mark its domain, qualifier, time and conditional basis.

This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 12: Anomalous result

Source passage: Portable XRF screening indicated anomalous zinc; laboratory assays are pending. Misleading translation: Certified zinc assays prove an ore zone. Meaning-preserving rendering: Field screening suggested anomalous zinc; confirmatory laboratory assay results are pending. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Screening evidence cannot be upgraded to accredited or definitive assay evidence by translation. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Check screening-device limitations, calibration record, pending sample IDs and laboratory method requisition. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

A repeatable edit sequence: First isolate the controlling noun or number from the source. Next mark its domain, qualifier, time and conditional basis.

In this case, the safe check is guided by Trace each interval from the drillhole name to from-to depths, length, grade, assay method and any statement on true thickness or orientation. Reproduce inclusive or exclusive endpoints as the actual source uses them. It is the linked set of checks, rather than a single dictionary lookup, that protects the reader.

Transfer test: Ask another reviewer to explain, without seeing the original drafting notes, what the source does and does not establish. Ask them to point to the evidence they would use to validate the conclusion. Then give them the misleading rendering and have them identify its extra assumption. If they cannot distinguish the two readings, the teaching note or translated qualifier is still insufficient. The same chain-of-custody habit helps translate laboratory results, medical measurements and engineering tests whose meaning depends on a sampling location. This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Diagnostic cluster 4: Sampling, laboratories and data-quality evidence

In this cluster, the controlling principle is the following: Sample integrity is a property of the measurement process. Translated reports must distinguish field duplicates, blank samples, reference materials, laboratory repeats, detection limits, contaminants, missing data and rejected assays; these are not interchangeable quality-control labels. The case is complete only when the classification, scope, evidence level and status of the assertion are mutually consistent across every language. In the field, the reviewer should read the nearest table or diagram and examine what the sentence does not claim as carefully as what it does claim.

Worked case 13: Blank contamination

Source passage: A blank inserted after the high-grade sample exceeded the laboratory trigger. Misleading translation: The blank was clean and validated the batch. Meaning-preserving rendering: The blank result exceeded the stated trigger and requires the source’s follow-up investigation. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Flipping failed to passed converts a warning about contamination into false confidence. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Review the blank certificate, high-grade sample position, batch sequence, investigation notes and re-assay decision. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

A repeatable edit sequence: First isolate the controlling noun or number from the source. Next mark its domain, qualifier, time and conditional basis. Then compare the proposed target phrase against the formal concept used elsewhere in the document. Finally read the phrase in the sentence and the sentence in its table or figure context. In this case, the safe check is guided by Map sample IDs, laboratory certificates, QA/QC thresholds, analytical methods, preparation methods and failure decisions to one stable naming convention. Keep failed checks visible in both narrative and tables. It is the linked set of checks, rather than a single dictionary lookup, that protects the reader.

Transfer test: Ask another reviewer to explain, without seeing the original drafting notes, what the source does and does not establish. Ask them to point to the evidence they would use to validate the conclusion. Then give them the misleading rendering and have them identify its extra assumption. If they cannot distinguish the two readings, the teaching note or translated qualifier is still insufficient. For anyone translating testing or compliance documentation, the quality-control result and its limitations matter as much as the numerical measurement. This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 14: Duplicate precision

Source passage: Field duplicates showed poor precision at low grade. Misleading translation: Repeated samples proved perfect agreement. Meaning-preserving rendering: Field duplicates showed limited precision in the low-grade range. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Precision varies with concentration; a broad ‘good agreement’ label hides the observed failure. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Inspect relative paired differences, detection limits, original and duplicate IDs, and the QA/QC plot. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 15: Below detection

Source passage: Assay result: <0.01% Cu. Misleading translation: The sample contains exactly zero copper. Meaning-preserving rendering: The reported concentration was below the 0.01% copper reporting limit. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Below a detection or reporting threshold is not equivalent to zero. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Check whether the source means detection limit or reporting limit, preserve the comparator and compare the lab’s units. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 16: Rejected batch

Source passage: Batch 14 was excluded pending laboratory investigation. Misleading translation: Batch 14 was accepted as fully validated. Meaning-preserving rendering: Batch 14 was excluded while the laboratory investigation remained open. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? The inclusion decision directly affects which observations may feed the resource model. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Reconcile the rejected sample list, data-freeze date, database flags and current investigation status. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Diagnostic cluster 5: Coordinates, spatial reference and mine geometry

In this cluster, the controlling principle is the following: A location in a geological table needs a coordinate reference system, datum, coordinate order and often vertical reference. Misleading conversions of eastings, northings, azimuths or metres can displace the apparent evidence or distort the size of a mineralised zone. The case is complete only when the classification, scope, evidence level and status of the assertion are mutually consistent across every language. In the field, the reviewer should read the nearest table or diagram and examine what the sentence does not claim as carefully as what it does claim.

Worked case 17: Datum omission

Source passage: Collars are reported in a project grid tied to a specified geodetic datum. Misleading translation: All collars are WGS 84 positions ready for navigation. Meaning-preserving rendering: Collar coordinates are in the project’s stated grid and datum, without an unverified conversion to WGS 84. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? A familiar map label can imply transformations the source does not document. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Request the survey-control description, transformation parameters, zone and datum before any conversion. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

A repeatable edit sequence: First isolate the controlling noun or number from the source. Next mark its domain, qualifier, time and conditional basis. Then compare the proposed target phrase against the formal concept used elsewhere in the document. Finally read the phrase in the sentence and the sentence in its table or figure context. In this case, the safe check is guided by Do not translate numeric coordinates into explanatory place names. Preserve identifiers, coordinate reference system metadata, decimal signs, orientation conventions and surveying status. It is the linked set of checks, rather than a single dictionary lookup, that protects the reader.

Transfer test: Ask another reviewer to explain, without seeing the original drafting notes, what the source does and does not establish. Ask them to point to the evidence they would use to validate the conclusion. Then give them the misleading rendering and have them identify its extra assumption. If they cannot distinguish the two readings, the teaching note or translated qualifier is still insufficient. Spatial literacy carries into mapping, infrastructure asset translation and incident evidence: a coordinate without its frame is an incomplete location. This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 18: Azimuth convention

Source passage: Hole azimuth is 075 degrees grid north, dip minus 60 degrees. Misleading translation: The hole points 75 degrees true north and dips upward 60 degrees. Meaning-preserving rendering: Azimuth 075 degrees relative to grid north; dip −60 degrees as reported. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Grid versus true reference and negative dip both alter three-dimensional interpretation. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Read the collar table header, grid convergence note and drill-survey convention. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

Worked case 19: Elevation reference

Source passage: The collar RL is 412 m in the mine survey datum. Misleading translation: The collar is 412 m above mean sea level. Meaning-preserving rendering: The collar reference level is 412 m in the stated mine survey datum. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? A local vertical reference is not automatically a sea-level height. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Compare surveying notes, vertical datum definition and other elevations on sections. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 20: Model boundary

Source passage: The resource estimate covers the shell shown in Figure 6, not the entire lease. Misleading translation: The whole property is a mineral resource. Meaning-preserving rendering: The estimated resource applies only to the delineated model shell shown in Figure 6. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Lease area and modelled mineralisation are different objects. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Trace polygon IDs, shell selection, section views and stated estimation boundaries. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Diagnostic cluster 6: Tonnage, volume, density and inventories

In this cluster, the controlling principle is the following: Tonnage is often a dry mass estimate derived partly from volume and density. A document that omits dry/wet basis, in-situ density, moisture and density-measurement method can generate numerical disagreements even when the digit sequence is copied perfectly. The case is complete only when the classification, scope, evidence level and status of the assertion are mutually consistent across every language. In the field, the reviewer should read the nearest table or diagram and examine what the sentence does not claim as carefully as what it does claim.

Worked case 21: Million versus thousand

Source passage: Estimated tonnage: 12.5 Mt. Misleading translation: The deposit has 12.5 thousand tonnes. Meaning-preserving rendering: The estimate reports 12.5 million tonnes, preserving the Mt prefix. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? A prefix change causes a thousand-fold scale error. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Check the column header, source spreadsheet formatting and independently recompute the displayed unit expansion. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

Then compare the proposed target phrase against the formal concept used elsewhere in the document. Finally read the phrase in the sentence and the sentence in its table or figure context. In this case, the safe check is guided by Record the mass basis, prefixes, rounding, density method and cut-off domain; compare every total with its component rows and flags for exclusions. It is the linked set of checks, rather than a single dictionary lookup, that protects the reader.

Transfer test: Ask another reviewer to explain, without seeing the original drafting notes, what the source does and does not establish. Ask them to point to the evidence they would use to validate the conclusion. Then give them the misleading rendering and have them identify its extra assumption. If they cannot distinguish the two readings, the teaching note or translated qualifier is still insufficient. Density and mass-basis reasoning applies to shipping, agriculture and chemistry wherever wet mass, dry mass and volume are not equivalent. This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 22: Dry versus wet tonnes

Source passage: The estimate reports dry metric tonnes after moisture correction. Misleading translation: The quoted quantity is the wet as-shipped tonnage. Meaning-preserving rendering: The reported mass is dry metric tonnes after the stated moisture correction. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Changing basis makes reconciliation with shipment and metallurgical figures unreliable. That is the pivotal difference, not a decorative change of terminology.

The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Find moisture assumptions, dry/wet conversion and reconciliation notes. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

Worked case 23: Bulk density

Source passage: Model blocks were assigned a bulk density of 2.65 t/m³. Misleading translation: All blocks contain 2.65 tonnes of metal per cubic metre. Meaning-preserving rendering: The model used a bulk density of 2.65 tonnes of material per cubic metre. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Rock mass per volume is not grade or contained metal. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Compare density test method, units, geology domains and model parameters. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision.

This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 24: Rounded total

Source passage: Rounded line items need not sum exactly to the rounded reported total. Misleading translation: The report’s total is mathematically wrong. Meaning-preserving rendering: The total and components are rounded independently; any apparent difference should be checked against unrounded values. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Rounding conventions affect interpretation of small discrepancies without authorising arbitrary edits. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Recalculate using original unrounded rows, model extract and report rounding policy. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym.

Diagnostic cluster 7: Grade units, contained metal and reporting bases

In this cluster, the controlling principle is the following: Grade, tonnage and contained material must be read together. Percent, grams per tonne, parts per million, ounces and pounds are not freely interchangeable labels, and conversions require attention to measurement basis, product type and rounding. The case is complete only when the classification, scope, evidence level and status of the assertion are mutually consistent across every language. In the field, the reviewer should read the nearest table or diagram and examine what the sentence does not claim as carefully as what it does claim.

Worked case 25: Percent versus g/t

Source passage: Copper grade is 0.75% Cu. Misleading translation: The grade is 0.75 grams of copper per tonne. Meaning-preserving rendering: Average grade is 0.75 per cent copper by mass. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? A percent-to-gram-per-tonne substitution changes magnitude by orders of scale. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Check commodity symbol, table header, grade definition and source unit. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

A repeatable edit sequence: First isolate the controlling noun or number from the source. Next mark its domain, qualifier, time and conditional basis. Then compare the proposed target phrase against the formal concept used elsewhere in the document. Finally read the phrase in the sentence and the sentence in its table or figure context. In this case, the safe check is guided by Freeze each physical unit with the number it qualifies. Keep grade, content and recoverable metal separate and reconcile only after verifying the source’s mass units and commodity conventions. It is the linked set of checks, rather than a single dictionary lookup, that protects the reader.

Transfer test: Ask another reviewer to explain, without seeing the original drafting notes, what the source does and does not establish. Ask them to point to the evidence they would use to validate the conclusion. Then give them the misleading rendering and have them identify its extra assumption. If they cannot distinguish the two readings, the teaching note or translated qualifier is still insufficient. The same discipline prevents medicine-dose, chemical-concentration and financial-unit mistakes across languages. This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 26: Gold grade

Source passage: Gold grade: 2.4 g/t Au. Misleading translation: The project contains 2.4 tonnes of gold. Meaning-preserving rendering: The grade is 2.4 grams of gold per tonne of material. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Concentration is not an inventory total and does not establish contained gold without tonnage. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Trace tonnage, assay basis and calculation statement before discussing contained quantity. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

A repeatable edit sequence: First isolate the controlling noun or number from the source. Next mark its domain, qualifier, time and conditional basis. Then compare the proposed target phrase against the formal concept used elsewhere in the document. Finally read the phrase in the sentence and the sentence in its table or figure context. In this case, the safe check is guided by Freeze each physical unit with the number it qualifies. Keep grade, content and recoverable metal separate and reconcile only after verifying the source’s mass units and commodity conventions. It is the linked set of checks, rather than a single dictionary lookup, that protects the reader.

Transfer test: Ask another reviewer to explain, without seeing the original drafting notes, what the source does and does not establish. Ask them to point to the evidence they would use to validate the conclusion. Then give them the misleading rendering and have them identify its extra assumption. If they cannot distinguish the two readings, the teaching note or translated qualifier is still insufficient. The same discipline prevents medicine-dose, chemical-concentration and financial-unit mistakes across languages. This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 27: Contained versus recovered

Source passage: The resource contains an estimated 160 kt of copper in situ. Misleading translation: The company will produce 160 thousand tonnes of copper. Meaning-preserving rendering: The estimated in-situ contained copper is 160 thousand tonnes; recoverable production is not asserted. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Economic and metallurgical constraints intervene between a modelled contained amount and saleable output. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Compare resource classification, recovery assumptions and production schedule. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision.

This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 28: Troy versus avoirdupois

Source passage: Gold content is expressed in troy ounces. Misleading translation: The figure is expressed in ordinary retail ounces. Meaning-preserving rendering: Gold content is expressed in troy ounces, using the source’s precious-metal convention. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Unit labels that look nearly identical may use different mass conventions. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Check whether the original number is troy ounces or metric tonnes and document any authorised conversion. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

A repeatable edit sequence: First isolate the controlling noun or number from the source. Next mark its domain, qualifier, time and conditional basis.

This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Diagnostic cluster 8: Cut-off grade, domains and estimation boundaries

In this cluster, the controlling principle is the following: A cut-off grade is a conditional reporting threshold, not an assay grade, a production target or an intrinsic property of every block. Classification and tonnage can change when cut-off assumptions change, so the denominator and reporting scenario matter. The case is complete only when the classification, scope, evidence level and status of the assertion are mutually consistent across every language. In the field, the reviewer should read the nearest table or diagram and examine what the sentence does not claim as carefully as what it does claim.

Worked case 29: Cut-off preserved

Source passage: Resources above a 0.35% Cu cut-off. Misleading translation: Resources grading 0.35% copper. Meaning-preserving rendering: Mineral Resources reported above a 0.35 per cent copper cut-off grade. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? A threshold is not an average; swapping them misrepresents the estimate. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Check model reporting assumptions and distinguish cut-off from reported average grade. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

A repeatable edit sequence: First isolate the controlling noun or number from the source. Next mark its domain, qualifier, time and conditional basis. Then compare the proposed target phrase against the formal concept used elsewhere in the document. Finally read the phrase in the sentence and the sentence in its table or figure context. In this case, the safe check is guided by Capture cut-off value, unit, conceptual economic basis, reporting date and selected geological domain. A different cut-off must be presented as a separate scenario, not merged with the base case. It is the linked set of checks, rather than a single dictionary lookup, that protects the reader.

Transfer test: Ask another reviewer to explain, without seeing the original drafting notes, what the source does and does not establish. Ask them to point to the evidence they would use to validate the conclusion. Then give them the misleading rendering and have them identify its extra assumption. If they cannot distinguish the two readings, the teaching note or translated qualifier is still insufficient. Conditional reporting thresholds appear in environmental monitoring and finance; the translated condition is part of the claim. This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 30: Scenario labels

Source passage: At 0.20% cut-off tonnage rises, while average grade declines. Misleading translation: The new method creates more ore with no trade-off. Meaning-preserving rendering: The lower cut-off scenario reports more tonnage at a lower average grade. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Tonnage-grade trade-offs cannot be smoothed away into a universal improvement claim. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Compare sensitivity-table rows, calculated metal content and cut-off assumptions. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 31: Copper equivalent

Source passage: CuEq was calculated using stated metal prices and assumed recoveries. Misleading translation: Copper-equivalent grade is directly measured copper. Meaning-preserving rendering: Copper-equivalent grade is a derived metric based on the stated price and recovery assumptions. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? An equivalent grade can combine commodities, but its meaning depends on disclosed inputs. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Find the exact CuEq formula and verify whether the components and recoveries are permitted for disclosure. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

Conditional reporting thresholds appear in environmental monitoring and finance; the translated condition is part of the claim. This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 32: Domain-specific threshold

Source passage: Oxide and sulphide material use different cut-off assumptions. Misleading translation: One grade threshold applies across the deposit. Meaning-preserving rendering: Different cut-off assumptions apply to the oxide and sulphide domains as specified. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Metallurgical routes and economics often differ by domain; a single invented threshold distorts both totals. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Compare domain codes, recovery assumptions, cut-off table and model filters. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym.

This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Diagnostic cluster 9: Mineral Resource confidence categories

In this cluster, the controlling principle is the following: Inferred, Indicated and Measured are defined classifications tied to geological knowledge and confidence, not promotional adjectives. The categories cannot be treated as interchangeable proof of the same degree of certainty. The case is complete only when the classification, scope, evidence level and status of the assertion are mutually consistent across every language. In the field, the reviewer should read the nearest table or diagram and examine what the sentence does not claim as carefully as what it does claim.

Worked case 33: Inferred not proven

Source passage: The estimate includes 5 Mt of Inferred Mineral Resources. Misleading translation: Five million tonnes of proven ore. Meaning-preserving rendering: The estimate includes five million tonnes classified as Inferred Mineral Resources. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Inferred is a specific lower-confidence resource category, not a statement of proven extraction. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Locate the classification table and check continuity, spacing and the reporting code’s definition. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

A repeatable edit sequence: First isolate the controlling noun or number from the source. Next mark its domain, qualifier, time and conditional basis. Then compare the proposed target phrase against the formal concept used elsewhere in the document. Finally read the phrase in the sentence and the sentence in its table or figure context. In this case, the safe check is guided by Check the exact capitalization, classification criteria, uncertainty statement and whether figures are broken out by category. Never translate confidence categories into ordinary-language certainty claims. It is the linked set of checks, rather than a single dictionary lookup, that protects the reader.

Transfer test: Ask another reviewer to explain, without seeing the original drafting notes, what the source does and does not establish. Ask them to point to the evidence they would use to validate the conclusion. Then give them the misleading rendering and have them identify its extra assumption. If they cannot distinguish the two readings, the teaching note or translated qualifier is still insufficient. Defined classifications require a concept-first glossary, just as grading systems and clinical evidence classifications do. This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 34: Indicated not measured

Source passage: The deposit includes 7 Mt of Indicated resources. Misleading translation: Seven million tonnes of measured reserves. Meaning-preserving rendering: Seven million tonnes are classified as Indicated Mineral Resources. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? The translated category must not advance one or two steps in confidence and economic implication. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Reconcile confidence category wording in text, figures, appendices and the resource-estimation database. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

Worked case 35: Measured not reserve

Source passage: Measured Mineral Resource: 2.5 Mt. Misleading translation: Proved Mineral Reserve: 2.5 Mt. Meaning-preserving rendering: Two point five million tonnes are reported as Measured Mineral Resources. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Even the higher-confidence resource category is not automatically a reserve. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Check whether the source has a separate reserve evaluation and modifying factors. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

A repeatable edit sequence: First isolate the controlling noun or number from the source. Next mark its domain, qualifier, time and conditional basis.

Defined classifications require a concept-first glossary, just as grading systems and clinical evidence classifications do. This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 36: Category aggregation

Source passage: Measured 2 Mt; Indicated 5 Mt; Inferred 3 Mt. Misleading translation: A single 10 Mt Measured resource. Meaning-preserving rendering: Measured, Indicated and Inferred quantities remain separately identified; a total must not erase the breakdown. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Combining without classification detail hides materially different levels of geological confidence. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Reconcile category rows and any policy governing presentation of combined Measured and Indicated figures. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

A repeatable edit sequence: First isolate the controlling noun or number from the source. Next mark its domain, qualifier, time and conditional basis.

This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Diagnostic cluster 10: Mineral Reserve declaration and modifying factors

In this cluster, the controlling principle is the following: Mineral Reserves add considerations beyond geological confidence, including mining, processing, metallurgical, economic, marketing, legal, environmental, social and governmental factors. The translator cannot convert a resource to a reserve by changing a noun. The case is complete only when the classification, scope, evidence level and status of the assertion are mutually consistent across every language. In the field, the reviewer should read the nearest table or diagram and examine what the sentence does not claim as carefully as what it does claim.

Worked case 37: Resource to reserve leap

Source passage: The resource may support future reserve conversion after further studies. Misleading translation: The company has established an ore reserve. Meaning-preserving rendering: The Mineral Resource may be evaluated for possible reserve conversion after further study. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Possibility of conversion is not the outcome of a reserve declaration. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Check the status of technical studies and the latest reported reserve table. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

A repeatable edit sequence: First isolate the controlling noun or number from the source. Next mark its domain, qualifier, time and conditional basis. Then compare the proposed target phrase against the formal concept used elsewhere in the document. Finally read the phrase in the sentence and the sentence in its table or figure context. In this case, the safe check is guided by Trace the parent resource category, reserve study, modifying factors, professional responsibility and distinction between Proved and Probable categories under the governing code. It is the linked set of checks, rather than a single dictionary lookup, that protects the reader.

Transfer test: Ask another reviewer to explain, without seeing the original drafting notes, what the source does and does not establish. Ask them to point to the evidence they would use to validate the conclusion. Then give them the misleading rendering and have them identify its extra assumption. If they cannot distinguish the two readings, the teaching note or translated qualifier is still insufficient. A determination based on several dependencies cannot be restated as a direct observation; the same logic holds for certification decisions. This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 38: Probable as certain

Source passage: Probable Mineral Reserve: 4.0 Mt. Misleading translation: A guaranteed four million tonnes of commercially mineable material. Meaning-preserving rendering: Four million tonnes are classified as Probable Mineral Reserves under the applicable reporting definition. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Probable is a defined reserve category, not a guarantee of actual future output. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Confirm reserve classification, reporting framework and qualifications around operating assumptions. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

Worked case 39: Proved not produced

Source passage: Proved Ore Reserve: 1.2 Mt. Misleading translation: The mine has already produced 1.2 Mt. Meaning-preserving rendering: The reported Proved Ore Reserve is 1.2 million tonnes. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Declared reserves are estimates for potential extraction, not historical production. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Compare production statements with reserve-estimation date and mine schedule. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision.

Ask them to point to the evidence they would use to validate the conclusion. Then give them the misleading rendering and have them identify its extra assumption. If they cannot distinguish the two readings, the teaching note or translated qualifier is still insufficient. A determination based on several dependencies cannot be restated as a direct observation; the same logic holds for certification decisions. This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 40: Modifying factor sensitivity

Source passage: The reserve case depends on a revised tailings design approval. Misleading translation: The reserve is independent of permitting and facility design. Meaning-preserving rendering: The reserve case depends on the specified tailings-design approval, as disclosed. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Removing a critical dependency can change the investment interpretation of the project. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Inspect permitting status, tailings study, reserve assumptions and material risks disclosed by the responsible professional. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

A repeatable edit sequence: First isolate the controlling noun or number from the source. Next mark its domain, qualifier, time and conditional basis. Then compare the proposed target phrase against the formal concept used elsewhere in the document. Finally read the phrase in the sentence and the sentence in its table or figure context. In this case, the safe check is guided by Trace the parent resource category, reserve study, modifying factors, professional responsibility and distinction between Proved and Probable categories under the governing code. It is the linked set of checks, rather than a single dictionary lookup, that protects the reader.

This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Diagnostic cluster 11: Mining methods, dilution and recovery

In this cluster, the controlling principle is the following: Mine plans distinguish ore scheduled for extraction, dilution added during mining, mining recovery, metallurgical recovery, loss and saleable product. A single generic word ‘yield’ erases distinctions that control both technical and economic calculations. The case is complete only when the classification, scope, evidence level and status of the assertion are mutually consistent across every language. In the field, the reviewer should read the nearest table or diagram and examine what the sentence does not claim as carefully as what it does claim.

Worked case 41: Dilution basis

Source passage: Mining dilution is assumed at 8% of the relevant material basis. Misleading translation: The ore grade is increased by eight per cent. Meaning-preserving rendering: The reserve model assumes eight per cent mining dilution on the basis specified in the source. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Dilution ordinarily adds non-ore material; it is not a bonus to grade. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Read the mining-method assumptions and clarify whether the percentage is defined on ore tonnes, total mined tonnes or another basis. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

A repeatable edit sequence: First isolate the controlling noun or number from the source. Next mark its domain, qualifier, time and conditional basis. Then compare the proposed target phrase against the formal concept used elsewhere in the document. Finally read the phrase in the sentence and the sentence in its table or figure context. In this case, the safe check is guided by Follow the material balance from modelled resource to reserve, mined ore, processed feed, concentrate and saleable product. Keep each percentage attached to its stage. It is the linked set of checks, rather than a single dictionary lookup, that protects the reader.

Transfer test: Ask another reviewer to explain, without seeing the original drafting notes, what the source does and does not establish. Ask them to point to the evidence they would use to validate the conclusion. Then give them the misleading rendering and have them identify its extra assumption. If they cannot distinguish the two readings, the teaching note or translated qualifier is still insufficient. Flow diagrams are translation aids whenever terms mark different transformations in a process rather than synonyms. This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 42: Mining recovery

Source passage: The mine plan applies 94% mining recovery. Misleading translation: The processing plant recovers 94% of metal. Meaning-preserving rendering: The mine plan assumes 94 per cent mining recovery at the extraction stage. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Mining recovery and processing recovery affect different links in the material chain. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Check the reserve model and processing test work separately. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

Flow diagrams are translation aids whenever terms mark different transformations in a process rather than synonyms. This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 43: Selective mining

Source passage: Narrow veins require selective mining to limit dilution. Misleading translation: All material can be mined indiscriminately. Meaning-preserving rendering: Selective mining is required for the narrow veins to manage dilution. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? The method constraint is central to the assumed mineability and cost. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Review vein widths, equipment dimensions, stope design and dilution assumptions. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

A repeatable edit sequence: First isolate the controlling noun or number from the source. Next mark its domain, qualifier, time and conditional basis. Then compare the proposed target phrase against the formal concept used elsewhere in the document. Finally read the phrase in the sentence and the sentence in its table or figure context. In this case, the safe check is guided by Follow the material balance from modelled resource to reserve, mined ore, processed feed, concentrate and saleable product. Keep each percentage attached to its stage. It is the linked set of checks, rather than a single dictionary lookup, that protects the reader.

Transfer test: Ask another reviewer to explain, without seeing the original drafting notes, what the source does and does not establish. Ask them to point to the evidence they would use to validate the conclusion. Then give them the misleading rendering and have them identify its extra assumption. If they cannot distinguish the two readings, the teaching note or translated qualifier is still insufficient. Flow diagrams are translation aids whenever terms mark different transformations in a process rather than synonyms. This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 44: Waste stripping ratio

Source passage: The preliminary plan gives a waste-to-ore stripping ratio of 4.2:1. Misleading translation: The ore grade is 4.2 per cent. Meaning-preserving rendering: The planned waste-to-ore stripping ratio is 4.2 to 1. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? A ratio of waste movement to ore movement is not a grade or recovery parameter. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Reconcile the ratio definition, units and pit-design schedule. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

A repeatable edit sequence: First isolate the controlling noun or number from the source. Next mark its domain, qualifier, time and conditional basis. Then compare the proposed target phrase against the formal concept used elsewhere in the document. Finally read the phrase in the sentence and the sentence in its table or figure context. In this case, the safe check is guided by Follow the material balance from modelled resource to reserve, mined ore, processed feed, concentrate and saleable product.

This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Diagnostic cluster 12: Metallurgy, processing and product specifications

In this cluster, the controlling principle is the following: Metallurgical testing describes how a particular sample behaved in specified conditions. Bench-scale recovery, plant design recovery, concentrate grade and impurities refer to different outcomes and cannot be conflated. The case is complete only when the classification, scope, evidence level and status of the assertion are mutually consistent across every language. In the field, the reviewer should read the nearest table or diagram and examine what the sentence does not claim as carefully as what it does claim.

Worked case 45: Laboratory recovery

Source passage: Bottle-roll tests recovered 78% of gold from selected samples. Misleading translation: The future mine will recover 78% from all ore. Meaning-preserving rendering: Selected bottle-roll tests yielded 78 per cent gold recovery under laboratory conditions. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? A lab result for selected samples is not a guaranteed life-of-mine plant performance. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Compare composite provenance, test conditions, ore variability and modelling assumptions. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

A repeatable edit sequence: First isolate the controlling noun or number from the source. Next mark its domain, qualifier, time and conditional basis. Then compare the proposed target phrase against the formal concept used elsewhere in the document. Finally read the phrase in the sentence and the sentence in its table or figure context. In this case, the safe check is guided by Track sample representativeness, test scale, process stage, metal deportment, recovery basis, payable product assumptions and whether a figure is achieved, designed or forecast. It is the linked set of checks, rather than a single dictionary lookup, that protects the reader.

Transfer test: Ask another reviewer to explain, without seeing the original drafting notes, what the source does and does not establish. Ask them to point to the evidence they would use to validate the conclusion. Then give them the misleading rendering and have them identify its extra assumption. If they cannot distinguish the two readings, the teaching note or translated qualifier is still insufficient. Evidence levels in trials and prototypes are not automatically operational performance; translators must preserve the scale of demonstration. This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 46: Concentrate grade

Source passage: Flotation produced a 24% copper concentrate in the trial. Misleading translation: The run-of-mine ore grades 24% copper. Meaning-preserving rendering: A trial flotation product was a concentrate containing 24 per cent copper. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Product enrichment is not the head grade of mined feed. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Check head grade, mass pull, concentrate yield and test certificate. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

Worked case 47: Impurity limit

Source passage: Arsenic in concentrate may attract a smelter penalty. Misleading translation: The product is certified as penalty-free. Meaning-preserving rendering: The source notes that arsenic may result in a smelter penalty. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? A conditional marketing risk must survive a polished commodity summary. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Inspect impurity assay results, indicative contract terms and any penalty schedules. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision.

Worked case 48: Representative sample

Source passage: The composite is considered preliminary and may not represent the entire deposit. Misleading translation: The test sample represents all future ore types. Meaning-preserving rendering: The composite was preliminary, with representativeness of the full deposit not established. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Sample representativeness controls how far results may be generalized. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes.

Diagnostic cluster 13: Economics, studies and financial sensitivity

In this cluster, the controlling principle is the following: Study labels and economic outputs are conditional. Scoping or preliminary economic analyses, pre-feasibility and feasibility studies are not synonyms. NPV, IRR, payback, discount rate, tax basis, price assumptions and confidence must stay attached to their assumptions and purpose. The case is complete only when the classification, scope, evidence level and status of the assertion are mutually consistent across every language. In the field, the reviewer should read the nearest table or diagram and examine what the sentence does not claim as carefully as what it does claim.

Worked case 49: Scoping study

Source passage: A scoping-level assessment suggests potential development options. Misleading translation: A final feasibility study proves the project is bankable. Meaning-preserving rendering: A preliminary scoping-level assessment examines possible development options. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Study maturity is a reporting fact, not a stylistic preference. That is the pivotal difference, not a decorative change of terminology.

The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Check scope, project stage, stated accuracy range and any caution on the use of Inferred Resources. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision.

This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 50: NPV discount

Source passage: The base-case NPV uses an 8% discount rate and stated commodity prices. Misleading translation: The mine has eight per cent guaranteed profit. Meaning-preserving rendering: The base-case net present value uses the stated eight per cent discount rate and assumed prices. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? A discount rate is not profit margin or a promised investment yield. That is the pivotal difference, not a decorative change of terminology.

Worked case 51: Price scenario

Source passage: Copper price sensitivity was calculated at three assumed prices. Misleading translation: The project locks in those copper selling prices. Meaning-preserving rendering: The study tests results under three assumed copper-price scenarios. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? An assumption in a model is not a signed sales contract. That is the pivotal difference, not a decorative change of terminology.

The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Trace scenario labels, commodity price units and marketing documentation. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision.

This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 52: Tax and royalties

Source passage: The model is reported on a pre-tax basis, excluding specified royalties. Misleading translation: The stated value is fully after tax and royalties. Meaning-preserving rendering: The figure is pre-tax and excludes the stated royalty treatment. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Tax basis can materially change comparability between projects. That is the pivotal difference, not a decorative change of terminology.

Diagnostic cluster 14: Geotechnical, groundwater and operational constraints

In this cluster, the controlling principle is the following: Slope design, ground support, water inflow and material handling can change the practical extraction envelope. A translated report must not confuse a design parameter with a measured universal condition or smooth away the need for further investigation. The case is complete only when the classification, scope, evidence level and status of the assertion are mutually consistent across every language. In the field, the reviewer should read the nearest table or diagram and examine what the sentence does not claim as carefully as what it does claim.

Worked case 53: Pit slope design

Source passage: Overall slope angles are preliminary pending geotechnical drilling. Misleading translation: The final safe pit angles have been approved. Meaning-preserving rendering: Pit slope-angle assumptions remain preliminary, pending geotechnical drilling. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? An unverified geometry can influence tonnage, waste movement and safety. That is the pivotal difference, not a decorative change of terminology.

Evidence and verification route: Check design report revision, geotechnical data availability and risk register. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

A repeatable edit sequence: First isolate the controlling noun or number from the source. Next mark its domain, qualifier, time and conditional basis. Then compare the proposed target phrase against the formal concept used elsewhere in the document. Finally read the phrase in the sentence and the sentence in its table or figure context. In this case, the safe check is guided by Keep angle reference, units, hydrogeological model status, contingency assumptions and named location-specific constraints only as technical properties, never as promotional certainty. It is the linked set of checks, rather than a single dictionary lookup, that protects the reader.

Transfer test: Ask another reviewer to explain, without seeing the original drafting notes, what the source does and does not establish. Ask them to point to the evidence they would use to validate the conclusion. Then give them the misleading rendering and have them identify its extra assumption. If they cannot distinguish the two readings, the teaching note or translated qualifier is still insufficient. When engineering design contains provisional limits, these qualifiers must be preserved in translation to prevent unsafe action. This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 54: Groundwater uncertainty

Source passage: Dewatering demand has not been confirmed by a pumping test. Misleading translation: The mine needs no groundwater management. Meaning-preserving rendering: Dewatering requirements are uncertain and pumping tests have not confirmed the demand. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Unknown water conditions are not evidence of zero inflow. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Review aquifer model, hydrogeological work plan and design basis. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

Worked case 55: Water balance

Source passage: Process water recycling is modelled at 65%, not yet demonstrated at plant scale. Misleading translation: Plant recycling already achieves 65%. Meaning-preserving rendering: The process model assumes 65 per cent water recycling; plant-scale achievement is not demonstrated. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? A modelled target and observed result are distinct claims. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Check flow balance, pilot testing, mass balance and assumptions. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

When engineering design contains provisional limits, these qualifiers must be preserved in translation to prevent unsafe action. This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 56: Tailings capacity

Source passage: The tailings design remains subject to final storage capacity verification. Misleading translation: The facility has unlimited approved capacity. Meaning-preserving rendering: Tailings storage capacity remains subject to final design verification. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Storage limits and approvals are operational constraints, not descriptive niceties. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Reconcile engineering drawing status, design capacity, material characteristics and approval records. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

A repeatable edit sequence: First isolate the controlling noun or number from the source. Next mark its domain, qualifier, time and conditional basis. Then compare the proposed target phrase against the formal concept used elsewhere in the document. Finally read the phrase in the sentence and the sentence in its table or figure context.

Diagnostic cluster 15: Permits, environmental effects and rehabilitation

In this cluster, the controlling principle is the following: A permit application, conditional approval, issued permit and completed compliance action are different statuses. Translators must keep environmental baseline data, mitigation commitments, closure obligations and rehabilitation provisions distinct. The case is complete only when the classification, scope, evidence level and status of the assertion are mutually consistent across every language. In the field, the reviewer should read the nearest table or diagram and examine what the sentence does not claim as carefully as what it does claim.

Worked case 57: Permit submitted

Source passage: The environmental application was lodged; determination is pending. Misleading translation: The environmental permit has been granted. Meaning-preserving rendering: The environmental application was submitted and remains under determination. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? A submission receipt is not the legal right to operate. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Read the application receipt, current permitting register and decision correspondence. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

A repeatable edit sequence: First isolate the controlling noun or number from the source. Next mark its domain, qualifier, time and conditional basis. Then compare the proposed target phrase against the formal concept used elsewhere in the document. Finally read the phrase in the sentence and the sentence in its table or figure context. In this case, the safe check is guided by Check the issuing authority, permit identifier, effective period, conditions, monitoring obligations, protected areas and conditions precedent. Do not invent consent from a project timetable. It is the linked set of checks, rather than a single dictionary lookup, that protects the reader.

Transfer test: Ask another reviewer to explain, without seeing the original drafting notes, what the source does and does not establish. Ask them to point to the evidence they would use to validate the conclusion. Then give them the misleading rendering and have them identify its extra assumption.

Permit-state fidelity matters in construction, pharmaceuticals and public administration as much as in mining. This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 58: Conditional consent

Source passage: Approval was issued subject to water-treatment conditions. Misleading translation: The project is approved with no restrictions. Meaning-preserving rendering: Approval is subject to the stated water-treatment conditions. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Conditions can be operational and financial constraints on a project. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Check the decision instrument, permit schedule and compliance milestones. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision.

Worked case 59: Baseline survey

Source passage: The biodiversity baseline is incomplete for the seasonal survey period. Misleading translation: The site has no sensitive species. Meaning-preserving rendering: Seasonal biodiversity baseline work remains incomplete. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Lack of data is not proof of environmental absence. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Inspect survey coverage, seasons, methods and outstanding work. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision.

Worked case 60: Rehabilitation estimate

Source passage: The closure cost estimate is preliminary and excludes long-term monitoring. Misleading translation: All rehabilitation liabilities are fully provided. Meaning-preserving rendering: The preliminary closure-cost estimate excludes long-term monitoring costs. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? An excluded cost component cannot disappear from a financial or public summary. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion?

This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Diagnostic cluster 16: Community, land access and governance

In this cluster, the controlling principle is the following: Public reporting often refers to consultation, agreements, access rights, cultural-heritage restrictions and community grievances. A translator must not turn engagement into consent, a proposal into a binding agreement, or a reported absence of complaints into proof of acceptance. The case is complete only when the classification, scope, evidence level and status of the assertion are mutually consistent across every language. In the field, the reviewer should read the nearest table or diagram and examine what the sentence does not claim as carefully as what it does claim.

Worked case 61: Consultation only

Source passage: Community consultation meetings have been held; agreement remains under negotiation. Misleading translation: The community gave unanimous consent to the mine. Meaning-preserving rendering: Consultation meetings were held, while an agreement remains under negotiation. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Participation in a meeting does not automatically constitute consent. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Review meeting records, representation, negotiation status and signed agreements. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

A repeatable edit sequence: First isolate the controlling noun or number from the source. Next mark its domain, qualifier, time and conditional basis. Then compare the proposed target phrase against the formal concept used elsewhere in the document. Finally read the phrase in the sentence and the sentence in its table or figure context. In this case, the safe check is guided by Identify who spoke, on behalf of whom, the procedural status, relevant document, evidence of authorization and any outstanding issue. Use neutral terminology rather than imposing the language of a different legal system. It is the linked set of checks, rather than a single dictionary lookup, that protects the reader.

Transfer test: Ask another reviewer to explain, without seeing the original drafting notes, what the source does and does not establish. Ask them to point to the evidence they would use to validate the conclusion. Then give them the misleading rendering and have them identify its extra assumption. If they cannot distinguish the two readings, the teaching note or translated qualifier is still insufficient. The method applies to humanitarian communication and contract translation: social legitimacy cannot be manufactured by paraphrase. This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 62: Access permission

Source passage: Temporary access for survey was granted, excluding drilling. Misleading translation: Full land access was secured for all mining activities. Meaning-preserving rendering: Temporary survey access was granted, with drilling excluded. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Scope of an access permission determines what activity is authorized. That is the pivotal difference, not a decorative change of terminology.

If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Check the actual permission document and activity restrictions. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

Worked case 64: Cultural heritage

Source passage: Work in the identified zone is subject to a further heritage assessment. Misleading translation: The heritage area has been cleared for development. Meaning-preserving rendering: Work in the identified zone remains subject to further heritage assessment. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? An assessment condition is not a clearance decision. That is the pivotal difference, not a decorative change of terminology.

Diagnostic cluster 17: Competent Persons, Qualified Persons and accountability

In this cluster, the controlling principle is the following: Competent Person and Qualified Person are regulated professional terms whose exact role depends on the controlling framework. A translator may explain a role but cannot create authorship, independence, registration or consent the source does not demonstrate. The case is complete only when the classification, scope, evidence level and status of the assertion are mutually consistent across every language. In the field, the reviewer should read the nearest table or diagram and examine what the sentence does not claim as carefully as what it does claim.

Worked case 65: Role-title substitution

Source passage: The report is signed by a Competent Person under the cited CRIRSCO-style code. Misleading translation: A Canadian Qualified Person certified the document. Meaning-preserving rendering: The report identifies a Competent Person under the cited reporting code. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? The two formal role labels must not be swapped merely for reader familiarity. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Verify code, professional affiliation, signatory, consent statement and applicable technical responsibilities. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision.

Then compare the proposed target phrase against the formal concept used elsewhere in the document. Finally read the phrase in the sentence and the sentence in its table or figure context. In this case, the safe check is guided by Keep the person’s name, qualification, professional-body membership, area of responsibility, consent language, signature date and conflicts separately traceable. Check whether the individual reviewed the translated text. It is the linked set of checks, rather than a single dictionary lookup, that protects the reader.

Transfer test: Ask another reviewer to explain, without seeing the original drafting notes, what the source does and does not establish. Ask them to point to the evidence they would use to validate the conclusion. Then give them the misleading rendering and have them identify its extra assumption. If they cannot distinguish the two readings, the teaching note or translated qualifier is still insufficient. Attribution and sign-off literacy is central to clinical, legal and academic translation: a language service is not the original expert’s certification. This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 66: Name and consent

Source passage: Consent was granted for the source-language report in the form and context presented. Misleading translation: The signatory has approved every translation and excerpt. Meaning-preserving rendering: The original report records consent for the form and context stated; separate translation approval is not implied. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Professional consent to one disclosure is not automatic endorsement of altered wording. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Compare written consent, translated scope, material changes and sign-off workflow.

Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

A repeatable edit sequence: First isolate the controlling noun or number from the source. Next mark its domain, qualifier, time and conditional basis. Then compare the proposed target phrase against the formal concept used elsewhere in the document. Finally read the phrase in the sentence and the sentence in its table or figure context. In this case, the safe check is guided by Keep the person’s name, qualification, professional-body membership, area of responsibility, consent language, signature date and conflicts separately traceable. Check whether the individual reviewed the translated text. It is the linked set of checks, rather than a single dictionary lookup, that protects the reader.

Transfer test: Ask another reviewer to explain, without seeing the original drafting notes, what the source does and does not establish. Ask them to point to the evidence they would use to validate the conclusion. Then give them the misleading rendering and have them identify its extra assumption. If they cannot distinguish the two readings, the teaching note or translated qualifier is still insufficient. Attribution and sign-off literacy is central to clinical, legal and academic translation: a language service is not the original expert’s certification. This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 68: Independence qualifier

Source passage: The Qualified Person is an employee of the reporting company. Misleading translation: An independent third-party expert certified the estimate. Meaning-preserving rendering: The Qualified Person is identified as an employee of the reporting company. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Employment or independence is a factual relationship relevant to understanding the disclosure. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Review employment disclosure, conflicts statement and qualified-person paragraph. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision.

This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Diagnostic cluster 18: Versions, effective dates and superseded claims

In this cluster, the controlling principle is the following: A resource statement is a dated estimate. A later technical study, depleted inventory, revised interpretation or corrected assay batch can change its scope. Translating the newest-sounding number without keeping date and status can create a false time series. The case is complete only when the classification, scope, evidence level and status of the assertion are mutually consistent across every language. In the field, the reviewer should read the nearest table or diagram and examine what the sentence does not claim as carefully as what it does claim.

Worked case 69: Effective versus issue date

Source passage: Report issued in October; resource effective as of June 30. Misleading translation: The estimate uses all information available through October. Meaning-preserving rendering: The report was issued in October, while the resource estimate is effective as of June 30. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Publication date does not tell us the technical data-freeze date. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Compare title page, effective-date statement and database cutoff. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

A repeatable edit sequence: First isolate the controlling noun or number from the source. Next mark its domain, qualifier, time and conditional basis. Then compare the proposed target phrase against the formal concept used elsewhere in the document. Finally read the phrase in the sentence and the sentence in its table or figure context. In this case, the safe check is guided by Separate issue date, effective date of estimates, data cutoff, audit date, signature date and amendment date. Build a revision map before cross-referencing numbers. It is the linked set of checks, rather than a single dictionary lookup, that protects the reader.

Transfer test: Ask another reviewer to explain, without seeing the original drafting notes, what the source does and does not establish. Ask them to point to the evidence they would use to validate the conclusion. Then give them the misleading rendering and have them identify its extra assumption. If they cannot distinguish the two readings, the teaching note or translated qualifier is still insufficient. Version control is essential whenever evolving evidence changes a claim, from legislation and public health to engineering and scientific publishing. This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 70: Superseded figures

Source passage: The former 2023 estimate has been superseded by the current estimate. Misleading translation: The 2023 and current resources should be added. Meaning-preserving rendering: The 2023 estimate is superseded and must not be aggregated with the current estimate. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Successive estimates describe overlapping material and cannot be summed as separate deposits. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Trace estimate history, depletion, new drilling and modelling change log. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 71: Erratum status

Source passage: An erratum corrects the unit in Table 8 but leaves the estimate unchanged. Misleading translation: The resource estimate was fully revised. Meaning-preserving rendering: The correction concerns a table unit; the source does not report a revised estimate. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? The scope of correction should neither be hidden nor inflated. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Check the formal erratum, referenced table and technical sign-off. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 72: Data gap

Source passage: Drillholes completed after the cutoff are not included. Misleading translation: All recent drilling confirms the current resource. Meaning-preserving rendering: Drillholes completed after the cutoff are excluded from the stated estimate. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Unmodelled data cannot retroactively be made part of the reported classification. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Compare drilling completion dates, model database and subsequent public statements. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

A repeatable edit sequence: First isolate the controlling noun or number from the source. Next mark its domain, qualifier, time and conditional basis.

Diagnostic cluster 19: Commodity-specific products and critical-mineral reporting

In this cluster, the controlling principle is the following: Mining projects report different measures for different commodities: concentrate, equivalent grade, recoverable product, lithium carbonate equivalent, rare-earth oxides and marketable materials. A commodity label is not always a pure-element mass. The case is complete only when the classification, scope, evidence level and status of the assertion are mutually consistent across every language. In the field, the reviewer should read the nearest table or diagram and examine what the sentence does not claim as carefully as what it does claim.

Worked case 73: Lithium compound basis

Source passage: The project reports lithium carbonate equivalent using a disclosed factor. Misleading translation: The stated tonnes are pure lithium metal. Meaning-preserving rendering: The quantity is expressed as lithium carbonate equivalent, using the stated conversion basis. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? The compound-equivalent figure and elemental lithium quantity are different physical measures. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Inspect formula, grade basis, factor and product-specification note. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

A repeatable edit sequence: First isolate the controlling noun or number from the source. Next mark its domain, qualifier, time and conditional basis. Then compare the proposed target phrase against the formal concept used elsewhere in the document. Finally read the phrase in the sentence and the sentence in its table or figure context. In this case, the safe check is guided by Define the exact product, chemical form, conversion factor, payable content and reporting purpose. Keep material available for sale separate from conceptual contained quantity. It is the linked set of checks, rather than a single dictionary lookup, that protects the reader.

Transfer test: Ask another reviewer to explain, without seeing the original drafting notes, what the source does and does not establish. Ask them to point to the evidence they would use to validate the conclusion. Then give them the misleading rendering and have them identify its extra assumption. If they cannot distinguish the two readings, the teaching note or translated qualifier is still insufficient. Chemical-species and product-form distinctions also matter in energy storage, pharmacology, food science and environmental reporting. This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 74: Rare-earth oxide mixture

Source passage: TREO is reported as total rare-earth oxides with a stated elemental mix. Misleading translation: The figure is pure neodymium metal. Meaning-preserving rendering: The stated total rare-earth-oxide metric must retain its oxide basis and composition qualifications. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? A mixture of oxides cannot be translated as one elemental product. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Check oxide list, laboratory method, reporting threshold and basis. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 75: Graphite product

Source passage: Flake size distribution was measured on test concentrate. Misleading translation: The ore body consists entirely of large flake product. Meaning-preserving rendering: The test concentrate has the reported flake-size distribution. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Processing changes particle distribution; a trial product result is not the total deposit composition. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Review feed sample, flotation process, classification method and product measurements. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

Worked case 76: Uranium expression

Source passage: Grade is stated as U3O8 equivalent. Misleading translation: Grade is elemental uranium of identical mass fraction. Meaning-preserving rendering: Grade is expressed on a triuranium-octoxide-equivalent basis. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Different chemical reporting bases require controlled conversions, not word substitution. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Confirm whether conversion is wanted, source basis, factor and regulatory reporting convention. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

Diagnostic cluster 20: Tables, graphics, translations and digital lineage

In this cluster, the controlling principle is the following: The text of a mining report is distributed across prose, figures, tables, attachments, spatial files and spreadsheets. Formatting and machine processing can alter numbers, labels, footnotes and links; translating only sentences fails to maintain the data relationships. The case is complete only when the classification, scope, evidence level and status of the assertion are mutually consistent across every language. In the field, the reviewer should read the nearest table or diagram and examine what the sentence does not claim as carefully as what it does claim.

Worked case 77: Table header drift

Source passage: Column A is tonnes; Column B is grams per tonne; Column C is contained ounces. Misleading translation: All three columns are relabelled as tonnes. Meaning-preserving rendering: Retain the original three distinct units and their column relationships. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? A cell value inherits its quantity type from its header. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Compare each header with data examples, formula definitions and the source workbook. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision. If evidence is unavailable, do not fill the hole with a confident synonym. Mark the uncertainty, request the source owner or technical professional to resolve it, and keep any unresolved point visible at handoff.

A repeatable edit sequence: First isolate the controlling noun or number from the source. Next mark its domain, qualifier, time and conditional basis. Then compare the proposed target phrase against the formal concept used elsewhere in the document. Finally read the phrase in the sentence and the sentence in its table or figure context. In this case, the safe check is guided by Treat captions, headers, figures, units, formula cells, references, alt text and annexes as a single controlled evidence set. Use bilingual change logs and validation reports at every export boundary. It is the linked set of checks, rather than a single dictionary lookup, that protects the reader.

Transfer test: Ask another reviewer to explain, without seeing the original drafting notes, what the source does and does not establish.

This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 78: Map legend loss

Source passage: The hatched polygon marks an untested target, not a resource boundary. Misleading translation: The hatched polygon is coloured as proved reserve. Meaning-preserving rendering: Use a legend that retains the untested-target status of the hatched polygon. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Figure semantics can overturn the correct wording in the main text. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Audit symbol meanings, figure revision and accessible figure description.

Worked case 79: Broken footnote

Source passage: The resource table notes that numbers may not sum due to rounding. Misleading translation: The footnote is removed during layout. Meaning-preserving rendering: Carry the rounding footnote adjacent to the translated resource table. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? Removing a footnote can manufacture the appearance of an error or hide the reporting basis. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes.

If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Compare PDF export, web table and source document footnote numbering. The reviewer should record the exact source location and whether it is a measurement, model result, assumption, dated classification, professional judgment or administrative decision.

This case is passed when the reviewer can recover the original limits without having to invent a professional approval or an unstated number.

Worked case 80: Machine export

Source passage: A decimal comma in the source becomes a field separator on CSV import. Misleading translation: The software reports a new tenfold grade. Meaning-preserving rendering: Keep the numeric value through locale-safe import and verify field delimiters and decimals. The accurate version is a model of claim control in English; a translator working into another language should express that same proposition naturally while preserving names, quantitative units and exclusions.

What is hidden behind the words? A locale conversion can silently corrupt a database without any visible translation mistake. That is the pivotal difference, not a decorative change of terminology. A careful reader should separate the surface sentence from the evidence state it describes. The first diagnostic question is therefore: what additional assertion would the misleading wording license in a downstream report, summary or meeting, and can the original source actually support that assertion? If not, the rendering is unacceptable even if its grammar is polished.

Evidence and verification route: Run row-count, numeric-range, checksum and sample-record reconciliation before release.

Transfer workshops: learn to read the claim before choosing the words

Workshop 1: The two-reader experiment

Give one reader a technical source sentence with a caveat and a second reader the proposed translation. Ask both what decisions they would confidently make. Document any difference in implied certainty, calculation basis, legal status or professional responsibility. Rewrite until the interpretations converge rather than simply counting matching keywords.

To extend this workshop, give the learner a second document containing a changed assumption and ask them to identify what must be revalidated before the target-language account can be reused. Require an evidence link, a revised definition if necessary, an exception log and a concise explanation for a non-specialist. The result should be a traceable decision about meaning, not a claim that the learner can certify a mine or rewrite a reporting obligation.

Workshop 2: The category-only audit

Hide all resource and reserve numbers while retaining categories and code references. Ask a reader to reconstruct the hierarchy of evidence in the report. If an Inferred figure now appears as Proved, the problem is conceptual and cannot be fixed by recalculating tonnage.

Workshop 3: The numbers-only audit

Strip the prose but keep values, units, comparator symbols, row names, footnotes and table references. Independently reconstruct the meaning of each quantitative field and verify its source. This reveals silent changes to percent, g/t, dry tonnes, equivalent grades, decimal conventions and totals.

Workshop 4: The scope reconstruction

Read every reference to project area, prospect, shell, stage, bench or material domain. Draw a small outline of which material is included, which is excluded and where the report has no evidence. Check whether a translated title quietly expands the scope beyond that outline.

Workshop 5: The provisionality map

Highlight modal verbs and time qualifiers: may, planned, subject to, pending, anticipated, as of, effective, excluded and superseded. Translate those phrases before translating the sentence’s headline nouns. A claim-strength map is often faster at preventing serious errors than proofreading ordinary adjectives.

Workshop 6: The source-of-authority check

Choose three technical claims and write down the supporting record and responsible professional for each. If one item depends on a standard, label the edition and its jurisdictional role. Do not let a translator’s useful clarification become a new certification statement.

Workshop 7: The figure and table handoff

Deliver a page in which the graph, its caption, its legend, the prose and the table refer to the same data. Ask a reviewer to search for conflict, not merely check individual segments. The most important error may be between two individually fluent parts.

Workshop 8: The non-adoption scenario

Give a team a proposed revision to a reporting code and a source report under the prior edition. Ask them to draft a target-language note describing the proposal without calling it current law. Separate the historical source claim from the current educational explanation.

Workshop 9: The machine-assistance trial

Translate one disclosure with and without automated assistance. Compare proper nouns, numbers, negatives, units, stage labels, scope and citations. The important score is not language smoothness but the count and severity of unsupported propositions that survive into the final draft.

Workshop 10: The product-chain diagram

Draw the path from in-situ model through mine plan, mined material, plant feed, recovered metal and saleable product. Label which number belongs to each stage. Translate the explanation without replacing one stage with another.

Workshop 11: The historical estimate test

Give the translator two reports from successive years with overlapping model domains. Ask them to explain why it is usually wrong to add the reported totals. Require the explanation to mention data freeze, update, depletion and supersession where relevant.

Workshop 12: The public summary exercise

Write a clear 120-word summary of a complex fictional mineral-resource table. Keep all material qualifiers: categories, effective date, cut-off, estimation status and named study basis. Then ask a non-specialist reader what is known, unknown and merely planned.

Frequently asked questions about mineral-resource and reserve translation

Can a translator change Mineral Resource to Ore Reserve for readability?

No. These are distinct formal categories. A reader-friendly explanation is possible, but the original classification must be preserved. A robust answer also names the controlling source document, relevant reporting edition and the evidence required for the particular disclosure. Readers should ask for clarification where those elements are missing, rather than assume that a fluent translation grants new technical authority.

Is an Exploration Target the same thing as an Inferred Mineral Resource?

No. An Exploration Target is conceptual and subject to its own qualifications; an Inferred Mineral Resource is a formally classified estimate under the cited code. A robust answer also names the controlling source document, relevant reporting edition and the evidence required for the particular disclosure. Readers should ask for clarification where those elements are missing, rather than assume that a fluent translation grants new technical authority.

Should I translate the name JORC or CRIRSCO?

Keep the official designation and give a concise explanation if the target audience needs it. Do not replace it with an unrelated standard. A robust answer also names the controlling source document, relevant reporting edition and the evidence required for the particular disclosure. Readers should ask for clarification where those elements are missing, rather than assume that a fluent translation grants new technical authority.

Does a report issued in 2026 automatically use a new 2026 mining code?

No. The report must be read for its named code and edition; a draft or ongoing review is not automatically an adopted standard. A robust answer also names the controlling source document, relevant reporting edition and the evidence required for the particular disclosure. Readers should ask for clarification where those elements are missing, rather than assume that a fluent translation grants new technical authority.

Can contained gold ounces be described as forecast production?

Not without an independently supported production assumption. Contained quantities and actual recoveries are different. A robust answer also names the controlling source document, relevant reporting edition and the evidence required for the particular disclosure. Readers should ask for clarification where those elements are missing, rather than assume that a fluent translation grants new technical authority.

What is the safest way to check a translated resource table?

Perform row-by-row bilingual reconciliation of names, classifications, tonnage, grade, contained content, units, cut-off and footnotes. A robust answer also names the controlling source document, relevant reporting edition and the evidence required for the particular disclosure. Readers should ask for clarification where those elements are missing, rather than assume that a fluent translation grants new technical authority.

How should missing assay values be translated?

Preserve their missing, below-limit or rejected status, including any symbol and reporting limit. Do not invent zeros. A robust answer also names the controlling source document, relevant reporting edition and the evidence required for the particular disclosure. Readers should ask for clarification where those elements are missing, rather than assume that a fluent translation grants new technical authority.

Does a Qualified Person approve a translation automatically?

No. Preserve what the original sign-off actually covers and obtain separate review or consent where necessary. A robust answer also names the controlling source document, relevant reporting edition and the evidence required for the particular disclosure. Readers should ask for clarification where those elements are missing, rather than assume that a fluent translation grants new technical authority.

May AI translate a technical mining report?

AI may assist drafting, but human technical and language review must catch unsupported claims, misclassified values, altered units and omitted qualifications. A robust answer also names the controlling source document, relevant reporting edition and the evidence required for the particular disclosure. Readers should ask for clarification where those elements are missing, rather than assume that a fluent translation grants new technical authority.

Should I translate a resource report into one universal English technical vocabulary?

Use a harmonized concept map for comprehension, while retaining the governing code’s actual names and distinctions. A robust answer also names the controlling source document, relevant reporting edition and the evidence required for the particular disclosure. Readers should ask for clarification where those elements are missing, rather than assume that a fluent translation grants new technical authority.

Why do cut-off grades need to remain visible?

They identify the conditions under which reported tonnages and grades were obtained and can materially affect comparisons. A robust answer also names the controlling source document, relevant reporting edition and the evidence required for the particular disclosure. Readers should ask for clarification where those elements are missing, rather than assume that a fluent translation grants new technical authority.

What does ‘world-facing’ translation mean here?

The explanation can serve readers across languages and jurisdictions without implying that any one country’s reporting rule applies universally. A robust answer also names the controlling source document, relevant reporting edition and the evidence required for the particular disclosure. Readers should ask for clarification where those elements are missing, rather than assume that a fluent translation grants new technical authority.

To study how meanings remain stable across languages in any subject, return to Master Art of Translation | The Complete System for Moving Meaning Between Languages. That parent explains general source reading, terminology, equivalence, translation quality and revision mechanisms without taking ownership of mineral-resource reporting.

To strengthen recognition of defined technical terms, use the Vocabulary Learning Hub; it provides the wider language-learning architecture rather than a second mining-code article. To understand how sentences state conditions, qualify evidence, attribute claims and explain uncertainty, visit How English Works | The Complete Map and Learning Routes. These links are optional extensions, not implied updates to the protected pages.

The final aim is modest but rigorous: make a document more accessible to someone who reads a different language without increasing the certainty, removing the conditions or changing the reporting authority behind a single material assertion. A translation succeeds when a target-language reader can tell what is known, how it was established, what remains unknown, whose professional judgment supports the claim and what should be checked before acting on it.
