A gold project is not close to production just because it has a feasibility study, a large resource estimate or a positive economic model. Look for a connected chain of evidence: a technically credible mine and processing plan, economically supportable reserves, a realistic path through permits and land access, adequate committed funding, and an executable construction and commissioning plan. Then distinguish first production from the company’s declaration of commercial production.
What stage has the project actually reached?
Start by identifying the latest completed milestone, not the most ambitious date in a presentation. Exploration, development, construction, operating production, closure and post-closure are different stages. An exploration target, initial assessment or economic study is not a construction decision, and construction is not proof that a mine has reached steady commercial operation.
The World Gold Council’s general lifecycle overview describes exploration as taking 1–10 years, development 1–5 years and operation 10–30 years. It also says a discovered deposit can typically take 10–20 years to reach production. These are broad, undated sector-level ranges, not a forecast for an individual project; location, project design and other circumstances affect timing.
What does the study label tell you?
Read the study name, its date and the disclosure rules the issuer says apply. Study labels have defined meanings under some reporting regimes, but they should not be treated as interchangeable marketing terms. The U.S. SEC’s Regulation S-K 1300 is one such framework; its definitions are U.S.-specific and are not universal legal rules.

- 12" POCKET SLUICE BOX WITH MINERS MOSS: A rubber riffle mat and miners moss trap heavy gold in a sluice small enough to carry anywhere. Use it to sample-test a gravel bar before hauling in big gear, clean up concentrates at home, or show kids how a sluice works.
- PATENTED SPIRAL RIFFLE GOLD PANS (US 12,582,996): Deep-walled 9" and 11" pans built like a classic prospector's pan, not a shallow dish. Aggressive riffles knock out light material fast, and the spiral riffles hold the fine flakes that flat-bottom pans wash away during finish panning.
- BLACK SAND MAGNET, SNUFFER BOTTLE & MAGNIFIER TWEEZERS: The separator magnet pulls black sand from your concentrates, the snuffer bottle vacuums gold flakes straight off the pan, and stainless magnifier tweezers let you spot and pick out flakes too small to grab by hand. Three glass gold vials hold the day's take.
- DESIGNED BY KEYESVILLE, CALIFORNIA PROSPECTORS: Sluice Fox kits are designed by prospectors who learned to pan in historic Keyesville, in California's Kern River gold country, and assembled in our own warehouses near the Sierra and Appalachian mountains. A gift that gets a family outdoors, from a brand that has been in the creek, not just a catalog.
Initial assessment
Under S-K 1300, an initial assessment is an early evaluation and cannot support disclosure of mineral reserves. A promising result at this stage is not equivalent to a demonstrated reserve or an investment-ready design.
Pre-feasibility study
A pre-feasibility study evaluates potential development options with less detail and confidence than a feasibility study. Under S-K 1300, it can support reserve determination only when the required demonstration and modifying-factor assessments are met; inferred resources cannot be used to demonstrate reserve economic viability under that framework.
Feasibility study
Under S-K 1300, a feasibility study is a comprehensive technical and economic assessment of a selected development option, with detailed consideration of applicable modifying factors and financial analysis. It may support a final proceed-or-finance decision. It does not establish that financing has closed, permits have been granted, construction has begun or the mine is operating.

Does the resource estimate support a reserve?
A mineral resource estimate describes material with geological evidence and confidence; a mineral reserve is the economically mineable part of measured or indicated resources after relevant modifying factors have been applied. Under S-K 1300, a proven reserve can come only from measured resources. Inferred resources carry too much geological uncertainty to support the specified reserve economic-viability demonstration and cannot be converted to reserves under this framework.
Check the qualified person’s assumptions and the bridge from resource to reserve, including mine design, dilution, mining losses and the factors that affect whether material can be extracted and sold. A reserve is not a guarantee that the mine will be built, and not every resource becomes a reserve. The applicable reporting code and definitions matter when comparing projects across jurisdictions.
Can the technical design produce saleable gold as modeled?
Trace the operating chain from ore in the ground to a product that can be sold. The study should connect the selected mine method and schedule to ore characteristics, metallurgical test work, process design, plant throughput, tailings and waste facilities, water, power, transport and supporting infrastructure. A break in that chain can undermine the production rate or cost assumptions even when the deposit itself is attractive.

- Execution: Does the study address engineering, construction schedules, production ramp-up and an execution plan at a level consistent with its stated maturity?
S-K 1300 calls for increasing rigor from pre-feasibility to feasibility. Its feasibility-study definition includes detailed assessments of applicable modifying factors; the study content addresses matters such as the selected mining method, schedules, process design, ramp-up, execution and permitting plans.
Do the economics survive less favorable assumptions?
Examine the assumptions behind the base case rather than relying on a headline net present value or internal rate of return. Review capital and operating costs, production, recovery, commodity prices, exchange rates, taxes, royalties, discount rate and financing requirements. Test how the economics change if costs rise, the schedule slips, recovery is lower or prices weaken.
Also ask whether there is a credible market for the planned product. Under S-K 1300, a feasibility study uses a reasonable commodity-price basis and detailed financial analysis. The regulation calls for market-study work in certain circumstances, including when a product lacks an established exchange-traded or other market and there is no sales contract. A positive modeled case is not a financing commitment or a guaranteed return.

Are permits, land and community matters on a credible path?
Make a project-specific list of approvals and rights required in its jurisdiction. Track each item’s status, conditions, dependencies, appeal or litigation exposure, and the party responsible for securing it. The list may include land access, water rights, environmental assessment, tailings approvals, closure obligations, consultation and agreements with local groups; the actual requirements depend on the project and local law.
The World Gold Council says companies must obtain appropriate permits and licences before construction. Under S-K 1300, pending permits do not automatically prevent reserve disclosure if a qualified person’s reasonable investigation finds no obstacle and timely approval is considered highly likely. That U.S. reserve criterion is not evidence that a particular project has its approvals, nor does it replace the local permitting process.
Is there a real construction and funding decision?
A feasibility study can inform an investment decision, but readiness requires evidence beyond the study. Look for a formal board or sponsor decision to proceed, committed and adequate financing, a funded plan for remaining work, and a credible owner and contractor team. Engineering and procurement maturity, delivery schedules, contingency, workforce and power availability, and commissioning and ramp-up plans help show whether the proposal can be executed rather than merely modeled.

- Decision: Has the sponsor explicitly approved construction, or is the project still seeking approval?
- Funding: Is financing committed and sufficient for the stated scope, including contingency and remaining development work?
- Delivery: Are engineering, procurement, contractors, schedule and owner responsibilities sufficiently defined?
- Start-up: Is there a practical commissioning and ramp-up plan, with production expectations that can be checked against actual results?
What does “commercial production” mean for costs?
First production and commercial production are not necessarily the same reporting milestone. Review the company’s stated operational criteria for declaring commercial production and identify what construction, ramp-up or other development work remains at that point.
World Gold Council all-in sustaining cost and all-in cost guidance says companies should decide at funding and execution approval which later development phases they will treat as non-sustaining after the commercial-production declaration, and disclose those phases clearly. As a result, reported AISC or AIC may not include every remaining project-development expenditure. Compare actual output, recovery and costs with the study’s assumptions as operations ramp up.
Are environmental, social and closure responsibilities built into the plan?
Assess environmental and social baselines, water and biodiversity management, tailings governance, worker safety, human rights, community engagement, closure funding, reclamation and post-closure monitoring. These are part of a project’s development and long-term obligations, not an optional afterthought to the production case.
The World Gold Council describes its Responsible Gold Mining Principles as a framework, while stating that it does not certify companies or assurance providers. A company’s statement that it aligns with the principles is therefore not, by itself, independent proof of conformance; where assurance is claimed, identify the provider and the scope. The WGC lifecycle overview says post-closure management typically continues for five to ten years or more, but actual obligations depend on applicable law and permits.

Compare projects on the same basis and under their stated reporting regimes. A more advanced-sounding label is not enough if the underlying assumptions, approvals or funding are less mature.
| Comparison area | What to check |
|---|---|
| Study maturity | Study type, date, selected option and applicable reporting code |
| Geology and reserves | Resource confidence, reserve support, assumptions, dilution and mining losses |
| Mine and process design | Design maturity, test work, recovery, throughput and product marketability |
| Site readiness | Infrastructure, water and power access, land rights and third-party dependencies |
| Approvals and relationships | Permit status and conditions, community agreements, consultation and dispute risks |
| Economics | Capital and operating assumptions, financing needs, and sensitivity to price, cost, schedule and recovery changes |
| Execution and funding | Construction decision, financing certainty, funding gap, delivery plan and ramp-up |
| Long-term obligations | Closure liabilities, post-closure obligations and disclosure of development spending after commercial production |
These comparison areas reflect factors addressed in S-K 1300 and the World Gold Council’s lifecycle and cost-disclosure guidance. Because the frameworks and approval systems vary, a real project should be assessed under its own jurisdiction’s reporting rules and permitting authorities.
