Most mining projects are built by small owner teams who bring in specialists for each stage: an exploration geologist to design the first program, a resource geologist to estimate tonnes and grade, mining and processing engineers to test whether it pays, and environmental and tailings experts to get it permitted. Here is when to consult mining specialists, which disciplines you actually need, what a Competent or Qualified Person is, and how to brief and select a firm without wasting budget.

Audience Owners, juniors, investors
If you are about to consult mining professionals for the first time, finding a firm is the easy part. The hard part is knowing which kind of expert you need, at which stage, and what they should hand back. Mining consultants range from a single independent geologist who logs core and writes a prospecting report, to global engineering houses with hundreds of staff who deliver full feasibility studies. Owners hire them for exploration design, resource estimation, mine planning, metallurgy, geotechnics, environmental permitting, tailings, closure and independent technical reviews for investors and stock exchanges.

The market is better structured than it looks from outside. The professional codes that govern public reporting of mineral projects (JORC in Australasia, NI 43-101 in Canada, S-K 1300 in the United States and SAMREC in South Africa) all define who may sign off technical work. That gives owners a clear first filter. Below: the disciplines, the study stages, what moves consulting fees, how to compare proposals, and where a satellite prospectivity read can cut what you spend before the first consultant ever travels to site.
“JORC, NI 43-101 and S-K 1300 each demand five years’ relevant experience before a professional signs public technical work.”
Consultants are paid for judgement, and judgement needs data. The more organised your maps, boundaries, historical results and objectives are before the first meeting, the less of the fee goes on discovery and the more goes on answers. That holds whether you consult mining engineers in Perth, geologists in Toronto or a tailings specialist in Johannesburg.
What mining consultants do across the project life
A mine goes through a long, staged life: grassroots exploration, target testing, resource definition (our guide to mineral exploration stages, methods and costs walks through the early steps), technical and economic studies, permitting, construction, operation and closure. At every step the owner can either build the skill in-house or consult mining specialists for a fixed scope. Most juniors and private owners do the latter. A permanent team covering every discipline is far too expensive for a project that may never reach production.
That is why the phrase “mining and exploration consulting” covers so much ground. A mining industry consultant might spend one month logging core in the Pilbara and the next reviewing a mine plan for a lender in London. What follows is the usual split of disciplines.
Mineral exploration consultants and geological consulting
Exploration specialists design and run programs: desktop reviews of past work, geological mapping at the right scale, soil and rock-chip sampling, geophysics planning (picking from the geophysical survey methods that suit the deposit), drill-hole design, core logging and interpretation. They also write the prospecting or exploration reports many licensing authorities ask for with renewals. Independent geologists and small geological consulting companies do much of this work, especially in Australia, Canada and Southern Africa, where many experienced professionals practise on their own account.
Resource estimation
Once there is enough drilling, a resource geologist builds a geological model and estimates tonnes and grade. If a listed company will publish the result, it must be signed off by a Competent Person (JORC, SAMREC) or a Qualified Person (NI 43-101, S-K 1300). This is the most regulated corner of mining consultancy services, and it is where the professional-membership rules below matter most.
Mining engineering consultants and mine planning
Mining engineers and mine planning consultants turn a resource into a mine design: open-pit shells or underground layouts, schedules, equipment fleets, operating and capital cost estimates, and finally the reserve. Underground mining consultants add stope design, ventilation and ground support. Mining consulting engineers of this kind feed the economic case at every study stage, which is why many owners also call them mining study consultants.
Most mining engineering consulting firms sell this work as a package with resource geology, because the reserve depends on both. If the study will back a listed company’s disclosure, the engineer signing the reserve section has to meet the same Competent or Qualified Person tests as the geologist, so ask the firm who that person is before you compare prices.
Metallurgy and processing
Metallurgists design the testwork program and the flowsheet, then estimate recovery and processing cost. For a gold project that might mean gravity, flotation or leach testwork. For a lithium project it covers concentrate grade and impurities. A project with an excellent resource but poor recovery rarely survives feasibility, so skipping this discipline is a false economy.
Geotechnical, hydrogeology and tailings
Pit-slope and underground stability, groundwater inflows and tailings storage design are specialist fields. For tailings in particular, the Global Industry Standard on Tailings Management (GISTM), launched on 5 August 2020 by ICMM, UNEP and PRI, sets 15 principles and 77 auditable requirements, including independent review. ICMM members committed to conform by August 2023 for facilities rated “extreme” or “very high” consequence, and by August 2025 for all others. Many owners retain a specialist firm purely to meet those expectations.
Environmental, social and closure
Environmental and social impact assessments, baseline studies, permitting strategy, community engagement and closure planning are often run by a separate consultancy. Lenders and many regulators expect this work to be credible and independent of the project’s promoters.
Independent review and due diligence
Investors, lenders and acquirers regularly consult mining firms to check someone else’s numbers. An independent technical review asks whether a resource, study or valuation is reasonable and flags the risks. It is one of the most common reasons non-miners go looking for a consultant at all. If you are the buyer of a small claim rather than a funded project, start with the title and boundary checks in our guide to gold claims for sale, then bring in a reviewer once the paperwork holds up.
Put the disciplines against the stages and a pattern appears. Early on you need one or two people. The crowd arrives at pre-feasibility.
When to consult mining specialists, and when you don’t need to yet
Not every question needs a consultant, and not every consultant needs to be a large firm. Owners overspend in two classic ways. They hire a full-service engineering house for a question an independent geologist could answer, or they skip independent advice at exactly the moment an investor or regulator will demand it. These triggers help you decide when to consult mining experts.
- ✔ You hold ground but don’t know what’s on it. Start with a desktop review and a first-pass target map. A single exploration geologist, supported by remote-sensing data, is usually enough.
- ✔ You are about to spend on drilling. Get a geologist to design the holes. A badly placed program is the most expensive mistake in early exploration.
- You plan to publish results or raise money on an exchange. You will need a Competent or Qualified Person who meets the relevant code, and often an independent report.
- You are buying, selling or financing a project. Commission an independent technical review from a firm with no interest in the deal.
- You are permitting a mine or a tailings facility. Environmental, geotechnical and tailings specialists are essential, and ICMM members have committed to GISTM’s independent-review requirements.
- ⚠ You don’t need a large firm yet if you only have a licence and a few surface samples. Spend the first budget on finding out where the prospective ground is.
Before you consult mining firms about fieldwork, get the whole licence area screened from orbit. A ranked target map lets a consultant spend their days on the ground that matters instead of walking the entire block. Draw your boundary on mining.farmonaut.com: Map Your Mining Site to start.
Competent Persons and Qualified Persons: the rules that shape the market
If your consultant’s work will support public disclosure, such as an exchange announcement, a prospectus or a technical report, the person signing it must meet a formal definition. The definitions come from a family of reporting standards coordinated through CRIRSCO (the Committee for Mineral Reserves International Reporting Standards). Its member codes include JORC, the Canadian CIM standards used with NI 43-101, SAMREC, PERC in Europe and the SME guide in the United States. When owners consult mining professionals for listed-company work, this is the first filter.
| Code / rule | Jurisdiction | Sign-off role | Minimum experience | Professional standing |
|---|---|---|---|---|
| JORC Code | Australia & New Zealand (ASX) | Competent Person | 5 years relevant to the deposit style and activity | Member or Fellow of AusIMM, AIG or a Recognised Professional Organisation |
| NI 43-101 | Canada (CSA) | Qualified Person | 5 years in exploration, mine development or operation, or project assessment | Engineer or geoscientist in good standing with a recognised professional association |
| S-K 1300 | United States (SEC) | Qualified Person | 5 years relevant to the mineralisation, deposit type and activity | Eligible professional organisation membership; employer and any affiliation disclosed |
| SAMREC Code | South Africa (JSE) | Competent Person | 5 years relevant to the work and deposit type | Registered with SACNASP, ECSA or SAGC, or member of SAIMM, GSSA, IMSSA or an RPO |
Two practical points follow. First, the “five years” is not five years of any mining work. Each code ties it to the deposit style and the activity. A geologist with long experience in coal is not automatically competent to sign off a gold resource. Second, the JORC Competent Person test is one of self-assessment: the professional must satisfy themselves that they meet the criteria and be able to explain it. As a client, ask them to do exactly that, in writing, before you sign an engagement letter.
Under Regulation S-K Subpart 1300, if the Qualified Person is not an employee of the company, the company must name the QP’s employer and disclose any affiliation with the company or with another party that holds an interest in the property. That is a useful model even for private deals. Always ask a consultant to declare any interest in the project, the vendor or the buyer. Canada’s equivalent definitions sit in the consolidated text of NI 43-101 published by the Ontario Securities Commission.
The quick check below applies the four codes’ shared tests to one candidate. It is a screening aid for owners, not a legal ruling; the professional still has to self-assess against the full code.
Competent or Qualified Person eligibility check
Assumptions: applies the five-year relevant-experience minimum and professional-standing tests summarised from the JORC Code, NI 43-101, S-K 1300 and SAMREC as checked in September 2026. It does not test degree requirements, deposit-style relevance or independence rules for specific report types. Codes change, so confirm with the exchange, regulator or professional body before engaging.
Hiring a consultant whose licence or membership is in the wrong jurisdiction for the report you need is a common and avoidable error. A South African geoscientist, for example, must by law be registered with SACNASP to practise. Look the person up on the register yourself, and confirm their experience matches your commodity and deposit type.
Study stages: what you are paying consultants to deliver
Most larger consulting engagements are framed around a study. The JORC Code and its counterparts use three levels: the Scoping Study (called a Preliminary Economic Assessment in Canada), the Pre-Feasibility Study (PFS) and the Feasibility Study (FS). Each carries more data, more disciplines and a tighter cost estimate than the one before.
- Scoping Study / PEA. An early look at whether the project could work. An AusIMM Bulletin article on feasibility studies puts typical scoping accuracy at around 30–35%, with some companies accepting ±50%. Under JORC, a scoping study must not be used as the basis for Ore Reserves.
- Pre-Feasibility Study. A more detailed evaluation of mining method, processing route and economics. Under JORC it is the minimum level of study needed to convert Mineral Resources to Ore Reserves. It is often used to attract partners or financing, or to decide whether a full feasibility study is justified.
- Feasibility Study. The study that removes major uncertainties, supports a construction decision and is typically what project lenders rely on.
How tight is “tighter”? There is no single international standard, and the AusIMM article says so plainly. One regulator that does write numbers down is the Cook Islands Seabed Minerals Authority: its S06 standard on scoping, pre-feasibility and feasibility studies asks for ±25% accuracy at pre-feasibility and ±10% at feasibility, with scoping at “order of magnitude”. Put those beside the AusIMM scoping band and the funnel is obvious.
What matters for a buyer of consulting services is the principle: you pay more at each stage because more disciplines are involved and more data is gathered. Commissioning a PFS before the geology justifies it is one of the fastest ways to burn capital.
“Under the JORC Code, a Scoping Study must not be used as the basis for estimating Ore Reserves.”
When a company announces a study, check which level it is, who signed it, and whether it leans on Inferred resources. A glossy scoping study is not a feasibility study. Ask whether the consultant who signed it is independent of the company and whether their experience matches the deposit type.
What drives the cost of mining consultancy services
Search for a day rate and you will find numbers. Treat them with suspicion. Consulting fees are quoted per scope, published rate cards are rare, and a figure without a scope attached tells you almost nothing. What you can control are the factors that drive the quote. Understanding them is the best way to compare proposals when you consult mining firms side by side.
- Stage and study level. A desktop review costs a fraction of a feasibility study, which involves many disciplines and months of work.
- Data quality. Clean, digital drill databases, surveyed collars and QA/QC records save days. Scanned paper logs and missing assay certificates add them.
- Site visits and logistics. Remote sites in Africa, northern Canada or the Australian interior add travel, security and camp costs.
- Seniority mix. A proposal staffed with junior geologists supervised by a senior CP is cheaper than one where the senior does everything, and often just as good.
- Independence and liability. Signing a public report carries professional liability, which is reflected in the price.
- ⚠ Scope creep. Vague briefs lead to variation orders. A tight scope with defined deliverables is the single best cost control.
The largest lever of all is how much ground the consultant has to cover. A geologist asked to map and sample an entire licence spends weeks. Give the same geologist a ranked shortlist of targets and the check takes days. That is where satellite prospectivity work fits, before you consult mining teams for field campaigns.
How to choose between mining consulting companies: a practical checklist
Looking for mining consultants in Australia, mining consultants in Canada or mining consulting companies in South Africa? The selection process barely changes between them. Run through these six checks before you consult mining firms, and again when their proposals come back.
1. Match the commodity: gold mining consultants are not interchangeable
Ask for three recent comparable jobs: same commodity, similar deposit style, similar stage. A firm with deep gold experience may be the wrong choice for a lithium brine, and copper mining consultants used to porphyry systems may not suit a sediment-hosted deposit. Specialist lithium mining consultants, metal mining consultants and industrial-minerals experts all exist.
2. Check professional standing yourself
Confirm membership of AusIMM or AIG (Australia), provincial engineering or geoscience registration (Canada), SACNASP or ECSA registration (South Africa), or the relevant body elsewhere. Registers are usually searchable online.
3. Confirm independence
For reviews and valuations, ask the consultant to declare any interest in the property, the vendor or the buyer, and any past work for either side.
4. Insist on a written scope
The proposal should list deliverables, data you will provide, site visits, assumptions, exclusions, schedule and a fee basis (lump sum, time and materials, or capped). Vague scopes are expensive.
5. Meet the person who will do the work
Large firms win work with senior names. Ask who will actually log the core, build the model and write the report, and how much of their time is committed.
6. Compare local and global firms honestly
Global mining consultants bring depth and bank-recognised names, which matters for feasibility studies and financing. Local firms, for example mining consultants in Perth or Brisbane (Australian mining engineering consultants signing ASX work must be AusIMM or AIG members under the JORC Code), mining consultants in Toronto, or geological consulting companies in South Africa, often bring regional knowledge, lower travel costs and faster mobilisation. Many projects use both.
Give every shortlisted firm identical inputs: licence boundary as KML, historical results, your objectives and your budget ceiling. Proposals become directly comparable, and the quality of each firm’s questions tells you a lot about how they will work.
Where satellite prospectivity work fits alongside your consultants
We are not a mining consultancy, a licensing agent or an engineering firm, and we don’t sign Competent Person or Qualified Person reports. What we do is the step that usually comes just before you consult mining geologists for fieldwork: a satellite read of the whole area, so the consultant’s time goes where the signal is strongest.
Our satellite-based mineral detection analyses multispectral and hyperspectral imagery of your boundary. Each mineral and alteration zone reflects energy in its own spectral signature, and we use that to flag likely mineralised target zones, alteration halos, and structures such as faults and fractures, without any ground disturbance.
- Input: coordinates, a KML/KMZ file or a polygon, plus the country and target mineral(s).
- Turnaround: 5–20 business days depending on area size and mineral complexity.
- 📊 Deliverables: prospectivity heatmaps, high-potential zones with estimated location and depth ranges, geological interpretation (faults, alteration, host rock), and PDF plus georeferenced GIS files your consultant can load directly.
- Premium+: adds TargetMax™ drilling intelligence: drilling-angle recommendations and interactive 3D subsurface models of vein structures and mineral distribution.
- 📊 Economics: satellite screening can cut early-exploration timelines from months to days and lower early-exploration cost by up to 80–85%.
- ⚠ Limitation: satellite targets are exploration targets, not a resource estimate. Field sampling and drilling, designed by your consultant, confirm them.
See what a typical deliverable looks like in the satellite-driven 3D mineral prospectivity mapping overview. We have scanned 100,000+ hectares for 20+ mineral types across 25+ countries. If you want a quote for your area, use our mining query form.
Satellite screening involves no ground disturbance. On community land or near sensitive habitats, it lets you and your consultants understand an area before any vehicle, trench or drill pad touches it, and target surface work only where it is likely to be worthwhile.
Before you consult mining teams for fieldwork, map the targets.
Send us your licence boundary. We’ll return a satellite prospectivity read (ranked target zones, geology and next steps) that your consultant can use to plan sampling and drilling.
How to brief a consultant: the data pack that saves fees
The fastest way to lower a consulting bill is to hand over a complete, well-organised brief. The list barely changes between a mine plan from engineers and a first program from a geologist. Assemble it once and reuse it for every firm you approach.
- Licence details: licence numbers, holder, grant and expiry dates, and the boundary as KML or coordinates in a stated datum.
- Objectives: what decision the work must support: drill or drop, raise funds, sell, permit, or build.
- Historical data: previous reports, maps, sample and assay results, drill logs, and any geophysics, in digital form where possible.
- Remote-sensing and target maps: satellite prospectivity maps, alteration and structural interpretations, in GIS format.
- Access and constraints: roads, seasons, security, community agreements and any restricted zones.
- Budget and timeline: a ceiling and a deadline let firms propose a realistic scope rather than a wish list.
- Reporting standard: whether the output must comply with JORC, NI 43-101, S-K 1300, SAMREC or a local regulation.
Red flags when you consult mining firms
- Guaranteed results. No honest consultant promises a discovery or a specific grade before drilling.
- Undeclared interests. A reviewer who also advises the vendor, or who holds shares, is not independent.
- Wrong experience. A CP or QP whose five years are in a different commodity or deposit type.
- No written scope. Open-ended time-and-materials work without milestones or a cap.
- ⚠ Offers to handle licensing “through contacts”. Licences are granted by the authority through its official process; be wary of anyone implying otherwise.
The best consulting relationships are staged. Commission a small, well-defined first job, judge the quality, then expand. Scaling up a good firm is far easier than unwinding a large contract with the wrong one.
Frequently asked questions
What does it mean to consult mining professionals?
It means hiring independent specialists (geologists, mining engineers, metallurgists, geotechnical, environmental or tailings experts) for a defined scope of work, rather than employing them full time. Owners, juniors, investors and lenders all use mining consultancy services at different stages of a project.
What is the difference between a Competent Person and a Qualified Person?
They are similar roles under different codes. The JORC and SAMREC codes use “Competent Person”; NI 43-101 in Canada and S-K 1300 in the United States use “Qualified Person”. All four require at least five years of relevant experience and membership or registration with a recognised professional body.
How much do mining consultants cost?
Fees depend on scope, study level, data quality, site logistics and the seniority of the team, and are usually quoted per job. A desktop review is a small engagement; a feasibility study is a large, multi-discipline one. Ask several firms to quote on the same written scope, and reduce the area they must cover by screening the ground first.
What do mining study consultants deliver at each stage?
A scoping study or PEA tests whether a project could work, usually to about ±30–35% accuracy according to AusIMM. A pre-feasibility study selects the development option and, under JORC, is the minimum basis for Ore Reserves. A feasibility study supports the construction and financing decision; the Cook Islands S06 standard, for example, asks for ±10% accuracy at that stage.
Should I choose a global mining consultant or a local firm?
Global firms bring depth and names lenders recognise, which matters for feasibility studies and financing. Local firms, such as mining consultants in Perth, Toronto or South Africa, often bring regional knowledge and faster, cheaper mobilisation. Many projects use a local firm for exploration and a larger firm for later studies.
Do I need a mineral consultant or a mining engineer first?
On an early licence, a mineral consultant (usually an exploration geologist) comes first: they review past work, map and sample, and decide whether the ground deserves drilling. When you consult mining engineers too early, you pay for mine designs on a deposit that has not been defined. Bring engineers in once a resource exists.
When should I consult mining engineers rather than geologists?
Geologists lead during exploration and resource definition. Mining engineering consultants become central once there is a resource to design a mine around, from the scoping study onwards, and for mine planning, scheduling and cost estimates during operations.
Is Farmonaut a mining consultancy?
No. We don’t provide engineering, legal or licensing services and we don’t sign CP or QP reports. We provide satellite-based mineral detection: ranked target zones, alteration and structural interpretation, and GIS-ready deliverables that your consultants can use to plan fieldwork more efficiently.
