Assess a pre-production gold miner by examining two things separately: whether its project can be built and operated on credible technical and economic assumptions, and whether the company can fund that work without undermining shareholders’ returns. Start with the latest qualified-person technical report and current company filings, then test the assumptions for resources and reserves, recovery, costs, schedule, permits, infrastructure, cash and dilution. A large resource estimate or a bullish gold-price scenario does not by itself establish that a mine is economic—or that its shares are attractively valued.
Start by identifying the project’s actual stage
Exploration results, a mineral resource estimate, an initial assessment, a pre-feasibility study, a feasibility study and a reserve declaration are different kinds of evidence. Do not treat a promising drill result or an early economic study as equivalent to a detailed plan for construction.
For a U.S. SEC registrant, look for the qualified-person technical report summary supporting disclosures about material properties. The SEC’s 2018 final rule describes the report summary as a basis for resource, reserve and exploration-results disclosures intended to help investors assess a property. Required material topics include property and ownership, geology, exploration and operating status, resource and reserve estimates, capital and operating costs, permitting, and the qualified person’s conclusions and recommendations. This reporting framework applies to SEC registrants; other jurisdictions may use different disclosure rules.
Record the technical report’s effective date, authors and qualifications, study stage, key assumptions and any updates. Compare management presentations with the filed report, and check whether a presentation relies on a newer study or selectively emphasizes a more favorable case.

Know what the study labels mean
A pre-feasibility study (PFS) assesses a range of technical and economic options after identifying a preferred mining method or pit configuration, processing method and sales plan. A feasibility study (FS) examines a selected option in greater detail, including modifying factors and financial analysis. They are not interchangeable, and neither guarantees financing, permits, construction or profitable operations. The SEC filing that reproduces these definitions is available here; consult the current regulation for authoritative wording.
Test what the resource and reserve figures really say
A mineral resource estimate is not proof that the material can be mined economically. SEC rulemaking notes that resources typically carry greater uncertainty than reserves. Ask how much of the stated resource has been converted into reserves, what assumptions support that conversion, and how much material remains outside the reserve estimate.
- Check the estimate’s foundation: review drilling density, sampling and quality-control procedures, geological interpretation, classification and cut-off grade in the technical report.
- Follow the metal through the process: distinguish contained metal from metal expected to be recovered, and from saleable product. Recovery assumptions and processing performance affect the economic value of the deposit.
- Read the mine plan: examine the reserve-backed mine life, planned grade and throughput, mining method, and the timing of production. A resource figure alone does not describe what the proposed mine is expected to produce.
Ask whether important metallurgical assumptions are supported by testing at a scale relevant to the proposed operation. Where recovery, processing performance or scale-up remains uncertain, treat the expected output and economics accordingly.
Challenge the economic case, not just its headline return
Study results such as net present value (NPV) and internal rate of return (IRR) depend on assumptions. Review the model’s gold and by-product prices, exchange rates, recovery, throughput, grade, mine life, capital costs, operating costs, sustaining capital, royalties, taxes, closure costs and schedule. Then examine the sensitivity analysis and downside cases, rather than relying on a single headline NPV or IRR.
Price, cost and recovery assumptions can materially change project economics and the amount of material that meets economic thresholds. The CK Gold Project S-K 1300 Technical Report and the 2021 CK Gold Project report illustrate project-specific risk categories; their assumptions and conclusions should not be applied to another property as if projects were identical.
Do not assume a gold-price forecast settles the question. A project’s economics can be affected by costs, recovery, schedule and other assumptions as well as the realized price of gold. The 2021 CK Gold report states: “There is no guarantee that metal prices will continue to support adequate revenues to cover the cost of mining and processing.” That is a project report’s caution, not a prediction about every gold company.
Look for buildability, permits and operating constraints
A project can have an attractive modeled return and still face material execution hurdles. Review how mature the engineering is, what metallurgical work remains, and whether the capital estimate includes suitable contingency. Check the proposed arrangements for equipment and contractors as well as access to power, roads, water and a workforce.
Map the approvals and dependencies that could affect the schedule. Separate permits already secured from those still required, and consider environmental studies, appeals or litigation, land access, water rights, community agreements and reliance on public infrastructure. Ask what a delay would mean for both the timeline and the company’s cash requirements.

Water supply and management, tailings and waste facilities, environmental conditions and closure obligations can all affect costs and the ability to operate. Filed project reports identify permitting delays, legal challenges, environmental complications and closure among relevant risk categories. For examples of the project-specific issues covered in reports, see the 2026 Hycroft Mine Project technical report, the 2026 Stibnite Gold Project technical report summary and the 2026 Grassy Mountain Project feasibility report. These reports illustrate diligence topics, not the risks or likely outcome of a different project.

Assess whether the company can finance the remaining work
Project quality and company financial strength are related but distinct. Use the issuer’s latest financial statements and subsequent filings to examine cash, debt, working capital, debt covenants and any committed construction funding. Compare available funds with the remaining development capital and expected schedule; a funding shortfall can lead to delays, new borrowing or share issuance.
Review the fully diluted share count and potential claims on the project’s economics, including warrants, options, royalties, streams, offtake terms and related-party commitments. Consider how much of the project the company owns and which funding obligations it must meet. These details are company-specific, so a general checklist cannot establish a particular issuer’s cash runway or likely dilution.

| Comparison area | What to line up |
|---|---|
| Study and disclosure | Study stage, technical report date and effective date |
| Mine plan | Reserve-backed mine life and grade; recovery assumptions and supporting test work |
| Economics | Initial and sustaining capital, operating costs, price and exchange-rate assumptions, and NPV or IRR sensitivities |
| Execution | Remaining permits, schedule, infrastructure and water needs, tailings and closure plans |
| Shareholder exposure | Ownership, royalties and streams, remaining funding needs, company cash and debt, and dilution exposure |
Use the technical report and current filings to fill in those comparisons. If a value or assumption is not disclosed on a comparable basis, do not infer that the projects are equivalent.
Keep project risk separate from share-value risk
A technically feasible project is not automatically a good investment at any share price. Consider the company’s enterprise value, ownership interest, fully diluted shares, funding obligations and project-stage uncertainty alongside the project’s technical merits. Without a named issuer and current filings, it is not possible to determine whether a particular company is fairly valued, adequately funded or likely to reach production.
