How do you translate mining geology, assay and mine-safety documents correctly without changing technical or compliance meaning? Treat mining documentation as a linked record of geology, samples, measurements, equipment, people, hazards, permits and project status. Accurate mining translation must preserve project identity, deposit and pit names, borehole and sample identifiers, assay units, geological observations, resource/reserve terminology, equipment states, safety classifications, environmental records, action status and revision history. A fluent target sentence can still be wrong if it changes a sample ID, turns an estimated grade into a measured grade, or converts a safety observation into a confirmed failure.
People searching for mining translation, mining document translation, geology translation, assay report translation, mine safety translation, mineral exploration translation, mining technical translation, mine equipment manual translation and mining compliance translation are working across exploration reports, drilling logs, laboratory certificates, resource models, mine plans, equipment documentation, safety records, environmental monitoring and regulatory submissions. The strongest translation workflow keeps geological identity, measurement status and compliance status separate instead of flattening everything into general mining language.
This guide explains how to translate mining documents without changing the technical record. It covers geology, boreholes, samples, assays, QA/QC, resource and reserve terminology, mine equipment, shift records, incident and safety records, tailings and water monitoring, permits, rehabilitation, community/environmental files, reporting status and final QA. It is about translation and document integrity, not mining engineering, blasting, extraction, investment or safety advice.
Mining Translation Is Evidence-and-Asset Preservation
Mining projects accumulate evidence over long lifecycles. A sample collected during exploration can later appear in a database, assay certificate, model, technical report and regulatory filing. Equipment and safety records likewise connect physical assets to events and actions. Translation should preserve those chains. The target should remain traceable to the same material, place, measurement, asset and procedural state as the source.
1. Identify the Mining Document Type
Classify the source before translating: geological report, drill log, assay certificate, sample register, resource report, mine-plan document, equipment manual, shift record, incident report, environmental record, tailings report, permit, rehabilitation plan, community document or regulatory filing. Each genre uses overlapping terminology differently. A geological interpretation is not an assay result, and an internal safety observation is not a regulator finding.
2. Record Project, Site and Revision Context
Capture company, project, mine, deposit, pit, underground area, plant or facility, document number, revision and effective date. Large mining groups can have similar naming across sites. Translation memory should carry project metadata so one site’s geology, equipment or permit terminology is not copied into another.
3. Preserve Project and Deposit Names
Project, prospect, deposit, pit, shaft, decline and plant names are often proper names or internal identifiers. Do not translate them by ordinary meaning unless the organisation has an official target form. Keep names consistent across reports, maps, databases and permits so the target remains traceable.
4. Preserve Coordinates and Survey References
Exploration and mine documents can contain latitude/longitude, grid coordinates, elevations, survey points and coordinate-system names. Protect every value and reference system. Do not convert coordinates or projections during translation. A correct place name with the wrong coordinate system can still misidentify a location.
5. Preserve Borehole and Drillhole Identifiers
Drillhole IDs, collar IDs, downhole intervals and sample identifiers are protected strings. Do not translate or normalise them. One character can refer to a different hole. Keep the same ID across logs, assay certificates, maps and technical reports.
6. Preserve Collar Information
Drillhole collars can include easting, northing, elevation, azimuth, dip and start date. Translate field labels while protecting values and units. Do not recompute or correct survey data unless authorised. The target record should reproduce the source collar record exactly.
7. Preserve Depth Concepts
Hole depth, interval from/to, true thickness, vertical depth and downhole distance can be different concepts. Translate the source term, not a general “depth.” A mineralised interval from 120–130 m downhole is not automatically ten metres true thickness. Geological interpretation belongs to specialists, not translation.
8. Preserve Core and Chip Terminology
Diamond core, reverse-circulation chips, cuttings and other sample media have different meanings. Use accepted target geological vocabulary. Do not translate every collected material as “rock sample.” Sample type can matter to logging, recovery and QA/QC records.
9. Preserve Lithology Terms
Rock types, alteration, structures and mineral assemblages should use target-language geological terminology and scientific conventions. If a project uses controlled abbreviations or codes, protect them. Avoid casual synonyms that could merge distinct lithologies. Geological consistency matters across logs and models.
10. Preserve Alteration and Mineralisation Language
Alteration, veining, mineralisation, oxidation and weathering can be observation or interpretation categories. Translate the source level of certainty. Do not make weak mineralisation “ore” or an interpreted alteration halo a confirmed resource. The target should preserve evidence, not commercial conclusions.
11. Preserve Structural-Geology Terminology
Fault, fold, shear, vein, fracture, contact and orientation terms can be technical and spatial. Use controlled target terminology and preserve measurements. Do not simplify a shear zone to “crack” or a geological contact to “boundary” where that loses meaning. Maps and text should use the same terms.
12. Preserve Sample Identifiers
Sample IDs connect field collection, preparation, assay and database results. Treat them like database keys. Do not translate or reorder them. A target assay table is unusable if the value is attached to another sample number even when the numeric result itself is correct.
13. Preserve Sample Type and Source
Channel, grab, core, chip, soil, stream-sediment, concentrate and other sample types can represent different collection contexts. Translate the category precisely. Do not imply representativeness or quality beyond what the source records. Sample method and result should remain separate.
14. Preserve Sample Interval
Drill or channel samples often have from/to depths or lengths. Keep numbers, units and direction. Do not convert an interval into a point measurement. Tables should retain row alignment so each assay result remains linked to the correct interval.
15. Preserve Recovery and RQD Terminology
Core recovery, RQD and related geotechnical fields are not general “quality” scores. Use standard target technical terminology, preserve percentages and symbols, and avoid turning measurement into interpretation. If a report later evaluates rock quality, translate that conclusion separately.
16. Preserve Chain-of-Custody Records
Sample dispatch and laboratory records can contain shipment, bag, seal, batch, courier and receipt data. Translate field labels and status while protecting IDs. Do not collapse dispatched, received and analysed into one “processed” state. Traceability depends on chronology.
17. Preserve Laboratory Identity
Assay certificates can identify laboratory, branch, method, certificate number, client and batch. Keep official names and codes. Do not replace the laboratory name with a parent-company brand if the certificate names a particular facility. Provenance matters to analytical records.
18. Preserve Assay Method Names
Laboratories use method codes and human-readable analytical methods. Protect method codes and translate descriptions only according to the lab’s terminology. Do not infer detection range or suitability from a method name. The target should remain a translation of the certificate, not an assay interpretation.
19. Preserve Analyte Names and Symbols
Gold, copper, silver, nickel, lithium and other analytes can appear as element names, chemical symbols or compound forms. Preserve the source form and unit. Do not substitute a metal name for an oxide or compound basis. Assay data can depend on how the result is expressed.
20. Preserve Units Such as ppm, ppb and Percent
Assays can be reported in ppm, ppb, g/t, %, mg/kg or other units. Protect unit and decimal precision. Do not convert unless authorised and verified. One result can change by orders of magnitude if the prefix or denominator is altered.
21. Preserve Detection-Limit Status
Below detection limit, above upper limit, not analysed, insufficient sample and no result are different statuses. Translate them distinctly. Do not convert “<0.01” to zero or “>10” to ten. Analytical qualifiers are part of the result.
22. Preserve Re-Assay and Overlimit Status
Laboratory records can show original result, overlimit method, repeat or re-assay. Keep method and status visible. Do not replace the original result silently. Later technical reports may need to know which value was superseded and why.
23. Preserve QA/QC Sample Types
Standards, blanks, duplicates and other QA/QC samples have different functions. Translate the category using the project glossary and protect IDs. Do not call every non-routine sample a “control.” Quality-assurance interpretation depends on the type.
24. Preserve Certified Reference Material Identity
Reference standards can have certified values, expected ranges, provider and lot. Protect standard ID and target value. Translation should not judge whether a result passes. Preserve the source record and any stated laboratory or project conclusion separately.
25. Preserve Duplicate Terminology
Field duplicates, coarse duplicates, pulp duplicates and laboratory repeats can differ. Translate each according to the project QA/QC system. Do not merge them into one generic duplicate category. Their purpose and stage in the sample chain differ.
26. Preserve QA/QC Status Without Reinterpreting It
QA/QC reports may classify samples or batches as acceptable, failed, outside tolerance, under review or requiring follow-up. Translate the recorded status exactly. Do not independently decide whether a standard or blank passed. The source project’s quality protocol controls the conclusion.
27. Preserve Composite and Interval Terminology
Technical reports can combine individual assays into composites over stated intervals. Translate composite, weighted average, interval and cutoff terminology carefully. Do not recompute grades or lengths. The target should preserve the source calculation and its assumptions.
28. Preserve Grade Versus Value
Ore or mineral grade is not simply “value.” Translate the measured or estimated concentration term accurately and keep unit. Do not turn a commodity price or economic value into grade language. Technical and financial measures should remain separate.
29. Preserve Cutoff Terminology
Reports may state a cutoff grade, reporting threshold or other selection rule. Translate the defined term and preserve the value. Do not infer why the cutoff was selected or apply it to new data. That is a technical/economic decision beyond translation.
30. Preserve Measured, Indicated and Inferred Status
Resource classifications can use defined confidence categories under particular reporting codes. Translate using the governing framework’s terminology and do not interchange categories. An inferred resource is not the same as an indicated or measured resource. Classification status is a central technical record.
31. Preserve Resource Versus Reserve
Mineral resource and mineral reserve are not synonyms. They can have defined meanings under reporting codes. Do not translate reserve as resource or vice versa. Use official terminology from the source jurisdiction or reporting framework and preserve category qualifiers.
32. Preserve Probable and Proven Reserve Categories
Where the governing code distinguishes probable and proven reserves, translate the exact category. Do not strengthen probable into proven. Technical confidence and modifying factors belong to qualified professionals and should remain as the source states them.
33. Preserve Reporting-Code References
Technical reports can cite JORC, NI 43-101, SAMREC, S-K 1300 or other frameworks. Protect the code name, edition, report title and competent-person references. Do not replace one code with another because the target market uses it more often.
34. Preserve Competent/Qualified-Person Roles
Reports may identify a Competent Person, Qualified Person or another formally defined professional role. Translate the official title under the relevant framework. Do not use a general “expert” label if the source identifies a regulated reporting role.
35. Preserve Technical-Report Status
Conceptual study, scoping study, pre-feasibility study, feasibility study, technical report and update can represent different stages. Translate the source study type. Do not call an early-stage study a feasibility study merely because it discusses economics.
36. Preserve Study Assumptions as Assumptions
Technical studies may rely on commodity price, recovery, cost, geotechnical or processing assumptions. Translate the assumption and unit without presenting it as fact. “Assumed recovery 85%” should not become “recovery is 85%.”
37. Preserve Mine-Plan Terminology
Open pit, underground, stope, bench, phase, pushback, decline, shaft and level can have specific meanings. Use controlled target terminology. Do not turn a planning unit into a physical asset if the source distinguishes them. The article preserves records, not mine-design decisions.
38. Preserve Development and Production Status
Mine records can distinguish development, production, pre-strip, stripping, waste movement, ore movement and rehabilitation. Translate the source status. Do not infer production from planned development. Operational records should remain descriptive rather than advisory.
39. Preserve Ore and Waste Classification
Ore, waste, low-grade stockpile, marginal material and other categories can be project-specific. Use the project glossary and preserve status. Do not reclassify material through translation. Economic or metallurgical decisions belong to the source process.
40. Preserve Stockpile Identity
Stockpiles can have IDs, grade categories, material type, location and tonnage. Protect identifiers and quantities. A target stockpile report should map to the same physical material. Do not rename a stockpile in a way that breaks database or survey references.
41. Preserve Tonnage and Mass Units
Mine reports can use tonnes, short tons, dry tonnes, wet tonnes or other bases. Keep the unit and moisture basis where stated. Do not convert or round without authorisation. Mass basis can materially affect reconciliation and reporting.
42. Preserve Density and Specific-Gravity Terms
Bulk density, dry density and specific gravity are different concepts. Translate them distinctly and preserve units. Do not use one general word for all density measures. Resource models and stockpile calculations depend on the distinction.
43. Preserve Recovery Terminology
Metallurgical recovery, plant recovery, extraction and yield can be different. Translate the source term and percentage. Do not turn recovery into ore grade. Process-test results and resource assumptions should remain clearly separated.
44. Preserve Metallurgical Sample Identity
Metallurgical composites, variability samples and testwork IDs are controlled records. Protect sample identity, source location and test programme. Do not merge a metallurgical composite with an assay sample simply because both originate from drill core.
45. Preserve Laboratory Testwork Status
Metallurgical or geotechnical testwork can be planned, underway, preliminary, final or superseded. Translate the status and revision. Do not make preliminary testwork appear final. Later design decisions may rely on the distinction.
46. Preserve Geotechnical Terminology
Rock mass, discontinuity, joint set, domain, slope, support class and other geotechnical terms have specialised meanings. Use approved target vocabulary. Do not simplify technical categories into general “rock quality” language where the source distinguishes them.
47. Preserve Ground-Control Record Status
Inspection records may contain observation, trigger, action, monitoring or closure status. Translate the recorded state without providing ground-control instructions. Do not make a monitored condition look resolved if the source says follow-up is pending.
48. Preserve Equipment and Fleet Identifiers
Haul trucks, loaders, drills, shovels, conveyors, crushers and other equipment can have fleet IDs and serial numbers. Protect them. Translate equipment descriptions consistently across maintenance, dispatch and safety records. Asset identity should remain stable.
49. Preserve Equipment State
Mine fleet systems can distinguish available, operating, standby, down, under maintenance, delayed and other states. Translate according to the site’s approved state model. Do not call standby “idle failure” or planned maintenance an unplanned breakdown.
50. Preserve Maintenance Work-Order Status
Work orders can be raised, planned, scheduled, in progress, completed, awaiting parts or closed. Translate the exact lifecycle state. Do not make a scheduled task look performed or a completed task look verified if the system separates those stages.
51. Preserve Part and Component Identity
Maintenance records can contain part numbers, component serials, assembly IDs and replacement history. Protect the identifiers and use manufacturer terminology. Do not substitute a generic part name if several similar components exist.
52. Preserve Inspection and Measurement Records
Equipment inspections can contain wear measurements, temperatures, pressures, clearances or visual observations. Translate the field labels and findings while preserving values and units. Do not diagnose equipment condition beyond the source record.
53. Preserve Safety-Event Categories
Mining safety systems can distinguish hazard, near miss, first-aid case, injury, equipment damage, high-potential event or other classifications. Use the site’s taxonomy. Do not turn every event into an accident. Category precision supports trend analysis and reporting.
54. Preserve Hazard and Risk Terminology
Hazard, risk, control, residual risk and exposure can have defined meanings. Translate them consistently. Do not use “danger” as a generic substitute. A risk assessment is a structured record, and the target should preserve its categories without re-rating them.
55. Preserve Risk-Rating Scales
Risk matrices can combine consequence, likelihood and rating. Keep numeric values, colour labels and category names aligned. Do not translate a medium risk into “serious” if that implies a higher category. Visual review should ensure colours and labels remain mapped.
56. Preserve Control and Action Status
Controls can be existing, proposed, assigned, implemented, verified or closed. Translate the status. Do not make a recommendation look like an existing control. Safety records depend on the distinction between what is in place and what still needs action.
57. Preserve Permit and Authorisation Status
Mines can use permits, work authorisations, access records and inspection approvals. Translate document type and state while preserving IDs and dates. This guide does not provide operational instructions; it preserves the record of what the source says was authorised.
58. Preserve Training and Competence Status
Worker records can distinguish trained, assessed, competent, authorised, expired or restricted. Translate each status exactly. Attendance at training is not automatically equivalent to competence or authorisation if the source system separates them.
59. Preserve Shift and Handover Records
Shift records can contain equipment state, production status, hazards, open work, weather and pending issues. Translate chronology and ownership faithfully. Do not convert an open item into a completed one. Handover records are evidence of what one team passed to another.
60. Preserve Blasting Records Without Adding Instructions
Mining records may reference blast IDs, locations, dates, responsible persons and post-event observations. Translate the record fields and status only. Do not provide explosive quantities, design methods or operational blasting instructions beyond what is necessary to preserve a source document’s identity.
61. Preserve Tailings-Facility Identity
Tailings records can identify storage facility, embankment, cell, pond, monitoring point or instrument by controlled name and code. Protect those identifiers. Do not simplify several facility components into one generic “tailings area.” Inspection, monitoring and regulatory records need the same physical-location mapping.
62. Preserve Tailings Monitoring Terminology
Reports can contain seepage, pore pressure, settlement, freeboard, water level, deformation or other monitored parameters. Translate each term using the project glossary and preserve value, unit and trend status. Do not convert an observed change into a safety conclusion unless the source explicitly does.
63. Preserve Trigger and Action-Level Status
Monitoring systems may distinguish normal, alert, trigger, action or other site-specific levels. Translate the source category without re-rating it. A reading that increased but remains below a trigger should not become “unsafe.” The target should preserve the recorded threshold relationship.
64. Preserve Inspection Finding Versus Recommendation
Tailings and infrastructure reports can distinguish observation, finding, recommendation and required action. Keep those categories separate. Do not turn a recommendation into a completed control or an observation into a nonconformance. Governance status is part of the technical record.
65. Preserve Water-Monitoring Point Identity
Surface-water, groundwater and discharge monitoring can use station, bore, well or sampling-point IDs. Protect the identifier, location, date and sample number. Do not rename a monitoring point because a target-language description sounds clearer. Historical datasets depend on stable names.
66. Preserve Water-Quality Parameters
Laboratory records can include pH, conductivity, metals, sulphate, suspended solids and other parameters. Translate the parameter name and preserve units, qualifiers and detection status. Do not decide whether a value complies unless the source report states the comparison and applicable limit.
67. Preserve Permit Limits Versus Internal Targets
Environmental records may show regulatory limits, licence conditions, internal trigger values or project targets. These are not interchangeable. Translate the source category and authority. Do not label an internal target as a legal limit or a legal limit as a voluntary objective.
68. Preserve Exceedance Status
If a report states that a value exceeds a limit, preserve parameter, result, limit, date and source conclusion. If the report says a value is near a limit, do not translate it as an exceedance. Compliance status should come from the source record, not translator inference.
69. Preserve Air-Quality and Dust Terms
Mining environmental records can include dust deposition, particulate matter, emissions, monitoring locations and weather context. Translate the approved parameter terminology and preserve units. Do not turn a monitoring result into a health or regulatory conclusion beyond the source.
70. Preserve Noise and Vibration Records
Monitoring reports can distinguish noise level, vibration, blast vibration, background and measured event. Translate the field and preserve units/timestamps. Do not infer causation or compliance where the source only reports a measurement.
71. Preserve Rehabilitation Terminology
Mine closure and rehabilitation records can use disturbance, reshaping, cover placement, revegetation, monitoring, relinquishment and other terms. Translate the source project’s controlled vocabulary. Do not make planned rehabilitation look completed or a trial area look site-wide.
72. Preserve Closure Status
Closure plans can be conceptual, approved, active, progressive, completed or under monitoring. Translate the exact lifecycle state. A closure plan is not closure completion. Long-term obligations should remain visible where the source records them.
73. Preserve Disturbance-Area Data
Environmental and rehabilitation records may show hectares disturbed, rehabilitated or remaining. Protect figures, units and dates. Do not recalculate totals unless authorised. The target should reproduce the official tracking record and its period.
74. Preserve Biodiversity and Species Records
Mine environmental reports can contain species names, habitat categories and survey observations. Preserve scientific names and observation status. Do not translate an observed species as a confirmed population trend or a habitat description as a regulatory designation unless the source does.
75. Preserve Cultural-Heritage Record Terminology
Projects can maintain heritage surveys, chance-find records, exclusion zones and consultation records. Translate official place/site names, record status and authority. Do not reveal or infer sensitive location detail not present in the authorised source. Cultural-heritage records can require controlled distribution.
76. Preserve Community and Stakeholder Roles
Documents can distinguish landholder, community, Traditional Owner, local authority, regulator, contractor and project representative. Translate the source role and use official names. Do not merge distinct groups into generic “stakeholders” when the record attributes a statement or agreement to one party.
77. Preserve Complaint and Grievance Status
Community records can show received, acknowledged, investigating, resolved, closed or referred status. Translate the lifecycle precisely. Do not make acknowledgement equal acceptance of a claim. Keep complainant statements separate from project findings.
78. Preserve Land-Access and Tenure Terms
Mining projects can involve leases, licences, permits, easements, access agreements and land-tenure records. Translate the source legal concept within its jurisdiction. Do not turn a limited access right into ownership or a permit application into an issued right.
79. Preserve Mining-Lease Identifiers
Tenement, licence, claim, lease and permit identifiers are protected data. Keep number, jurisdiction, holder and status exact. A translated project report should map to the same legal tenure shown in the official register.
80. Preserve Tenure Status
Applications, granted licences, renewals, expiries, relinquishments and suspensions represent different states. Translate each state exactly. Do not present a pending application as an active right or an expired licence as current.
81. Preserve Royalty and Production-Report Labels
Regulatory and commercial records can contain production quantities, royalty bases, payment periods and commodity names. Translate labels and preserve values. Do not calculate royalty obligations or interpret tax/financial consequences beyond the source.
82. Preserve Shipping and Concentrate Identity
Mining sales and logistics can involve ore, concentrate, doré, product lots or bulk shipments. Translate commodity descriptions and protect lot, batch, vessel or shipment references. The Shipping, Freight and Customs owner covers the wider logistics layer.
83. Preserve Assay and Moisture Certificates in Sales Records
Commercial mineral shipments can include certificates for grade, moisture or other properties. Translate the certificate fields while protecting sample, shipment and analytical identifiers. Do not convert a provisional assay into a final settlement assay if the source distinguishes them.
84. Preserve Contractual Specification Terms
Sales contracts can define product specifications, penalties, payability, delivery or other terms. Translate defined terms consistently and keep specification data separate from assay results. The Contracts and Legal Clauses owner provides the formal agreement framework.
85. Preserve Technical-Due-Diligence Status
Due-diligence records may contain verified fact, management representation, open question, risk, assumption and recommendation. Keep those evidence levels distinct. Do not turn an open item into a confirmed problem or a management statement into independent verification.
86. Preserve Data-Room File Identity
Mining transactions often involve large technical data rooms. Translate file names, document titles and indexes while preserving document number, revision and date. Do not detach a target translation from the source file it represents. Cross-references should remain stable.
87. Preserve Regulatory-Submission Status
Reports may be draft, filed, accepted, returned, approved or published. Translate the exact procedural status. Do not make a submitted report look regulator-approved or a public technical report look equivalent to an internal model.
88. Preserve Public-Disclosure Language
Market disclosures can contain technical results, forward-looking statements and qualified professional attribution. Translate the same certainty and caveats. Do not strengthen preliminary exploration results into discovery, resource or reserve language. Public-market consequences belong to qualified legal/technical review.
89. Preserve Competent-Person Consent References
Some reporting frameworks require named professional consent or statements. Translate the role, name, professional affiliation and scope accurately. Do not imply consent to a different document or updated result unless the source shows it.
90. Maintain One Mining Termbase
Link geology, sample, assay, resource, mine-planning, equipment, safety, environmental and regulatory terminology. Contextual variants are acceptable when documented. The goal is one traceable technical concept model across the project lifecycle.
91. Use Translation Memory With Project Metadata
Tag segments by project, deposit, document type, reporting code, site and revision. Review high matches containing grades, units, resource categories, safety states and identifiers. Reuse should not transfer another project’s geology, limits or legal status.
92. Run a Sample-and-Assay QA Pass
Compare hole ID, sample ID, interval, laboratory, method, analyte, result, qualifier and unit. A single row shift can attach the right number to the wrong sample. Data QA should be independent of prose review.
93. Run a Resource/Reserve Terminology QA Pass
Search every occurrence of resource, reserve, inferred, indicated, measured, probable and proven or their governing-code equivalents. Verify that category strength remains unchanged. These words should never be stylistic synonyms.
94. Run a Numerical QA Pass
Extract depths, intervals, grades, percentages, tonnes, densities, recoveries, monitoring results and dates. Compare units, decimals, signs, less-than/greater-than qualifiers and table positions. Mining documents are too data-dense to rely on normal proofreading alone.
95. Run an Identifier QA Pass
Compare project IDs, hole IDs, sample IDs, lot IDs, equipment IDs, permit numbers, tenement IDs and certificate numbers. Treat them as database keys. Identity errors can break traceability across years of project data.
96. Run a Status QA Pass
Check preliminary/final, observation/finding, hold/released, proposed/completed, submitted/approved and open/closed states. A target record should stay at the same lifecycle stage as the source. Status drift is one of the most common hidden translation errors.
97. Review Maps, Tables and Charts After Layout
Drill tables, assay certificates, cross-sections, maps, risk matrices and monitoring graphs depend on spatial relationships. Review final rendering. A correct translation beside the wrong hole, interval, curve or risk cell is incorrect technical information.
98. Version-Control Target Mining Documents
When assay certificates, resource models, permits, safety registers or environmental reports change, update dependent translations through controlled release. Archive superseded target files clearly. Old technical translations can remain plausible long after they cease to be current.
99. Separate Translation From Mining Decisions
Translators should not estimate resources, design mines, choose cutoffs, interpret assays, set blasting parameters, decide equipment actions, assess tailings safety or determine environmental compliance. Apparent source issues should go to authorised geologists, engineers, safety or regulatory professionals.
Worked Example: Assay Result
Source certificate shows Sample M-104: Au 1.25 g/t, method FA-01, result final. Preserve sample, analyte, value, unit, method and status. Translating g/t as % or moving the result to M-105 breaks the record completely.
Worked Example: Resource Classification
Source says “Inferred Mineral Resource.” The target must use the governing framework’s corresponding term and retain “inferred.” Translating it as a general “mineral reserve” materially overstates technical and economic status.
Worked Example: Tailings Monitoring
Source: “Seepage increased from prior month but remains below Action Level 1.” Preserve trend and threshold relationship. “Unsafe seepage detected” invents a conclusion the source does not make.
Worked Example: Incident Investigation
Source: “Possible fatigue cracking identified as a contributing factor; root cause review ongoing.” Preserve possibility, contributing-factor status and ongoing review. “Fatigue cracking caused the incident” overstates evidence.
Mining Translation QA Matrix
| Dimension | Check | Typical failure |
|---|---|---|
| Identity | Project, hole, sample, asset, permit | Broken traceability |
| Geology | Lithology, interval, interpretation | Changed evidence |
| Assay | Analyte, unit, qualifier, method | Changed result |
| Classification | Resource/reserve confidence | Overstated status |
| Safety/environment | Risk, finding, trigger, compliance | Wrong governance state |
| Layout | Tables, maps, charts, matrices | Correct data in wrong context |
A Seven-Pass Mining Review
Use a project/context pass; a geology/sample pass; an assay/numerical pass; a resource/reserve terminology pass; a safety/environment status pass; an identifier/traceability pass; and a final map/table/chart rendering pass. High-consequence content should receive qualified mining subject-matter review.
Common Mining Translation Failure Modes
- Changing a hole or sample identifier.
- Converting below-detection results into zero.
- Confusing ppm, g/t and percent.
- Turning an inferred resource into a reserve.
- Changing study stage or competent-person status.
- Reclassifying ore, waste or stockpile material.
- Turning an anomaly into a confirmed defect.
- Changing risk, trigger or permit status.
- Moving assay values to the wrong table row.
- Leaving superseded target technical reports in circulation.
How AI Can Help—and Where It Must Stop
AI can help extract identifiers, compare revisions, flag inconsistent geological terms and detect number mismatches. It can assist low-risk drafting in approved secure systems. It should not estimate resources, classify reserves, interpret assay programmes, make safety decisions or determine environmental compliance. Human technical review remains essential.
Practice and Transfer
Use a fictional mining project with invented drillholes, samples, assays, a mock resource table and a harmless safety/environment record. Translate the set and verify IDs, intervals, units, categories and status. Use fictional data only. This trains mining record discipline without giving extraction or investment advice.
Authoritative Reference Route
The existing Why Translation Matters in Mining and Minerals article provides the broader rationale. For real projects, use the governing reporting code, regulator, laboratory, operator and site terminology as authoritative sources for the source jurisdiction.
Frequently Asked Questions
What is mining translation?
It covers geology, drilling, assays, resource reporting, mine equipment, safety, environmental monitoring, permits, rehabilitation and mining technical records.
Why are assay units high risk?
Small unit or qualifier changes can alter results by orders of magnitude or change how a value is interpreted.
Are resources and reserves the same?
No. They are distinct technical/reporting categories and should follow the governing code’s terminology.
Can AI translate mining technical reports?
AI can assist with terminology and QA, but classification, safety, environmental and technical conclusions require qualified human review.
Where This Article Sits in the Translation Architecture
This article owns the mining technical-record lane inside Master Art of Translation. It complements Why Translation Matters in Mining, Technical Instructions and Manuals, Environmental and Sustainability Disclosures, and Terminology and QA.
The Principle to Keep
Mining translation is correct when the target preserves the same project, sample, assay, classification, asset, safety state, environmental record and revision as the source. Translate the evidence and technical record, not a new geological or operational conclusion.
