A resource estimate or positive study is only one link in that chain—not proof of a profitable mine, secured permits, or enough financing.
Start with the issuer, project and disclosure rules
Begin with the company’s latest annual report and material-change filings, then find the technical report for the specific project. Record the report’s effective date, the company’s ownership interest, and the disclosure regime: for example, the U.S. SEC’s S-K 1300 or Canada’s NI 43-101. The terms and methods used under different regimes may not be directly comparable. Agnico Eagle’s 2025 annual information form and management discussion, filed in 2026, notes that some Canadian issuers reporting through the SEC’s Multijurisdictional Disclosure System may continue to use NI 43-101 and that their resource and reserve information may differ from comparable disclosures by U.S. companies.
Do not compare headline tonnage or contained metal until you have checked the resource definitions, ownership basis, cut-off assumptions, report date and technical-report scope. For a materials company whose project is downstream from a mine, identify what the project actually depends on—such as a proposed mine, purchased feedstock or another supply arrangement—and whether the company has evidence that supply can be secured. A mining technical report does not, by itself, establish the economics of a separate processing or materials business.
What do exploration results, resources and reserves actually establish?
These terms describe different levels of evidence. Exploration results are not automatically a resource; a resource estimate is not a reserve; and a reserve estimate is not a promise of profitable production.

#1 Best Overall
| Disclosure | What it establishes | What it does not establish |
|---|---|---|
| Exploration results | Reported findings from exploration work; read the underlying disclosure to see what was sampled and how results are presented. | By themselves, they do not establish a mineral resource, reserve, or economic project. |
| Inferred resource | A mineral resource category with the lowest geological confidence among the categories described in the cited issuer disclosure. | It cannot be treated as a reserve or used to assume economic viability. The disclosure cautions against assuming inferred material exists as described or is economically or legally mineable. |
| Indicated resource | A resource category with greater confidence than inferred, but less confidence than measured. | It is not a reserve and does not guarantee conversion or economic extraction. |
| Measured resource | A resource category with greater geological confidence than indicated. | It is not automatically a reserve; conversion and realized production are not guaranteed. |
| Mineral reserve | A stronger project claim than a resource: it reflects applying modifying factors and demonstrating economic extraction within a study framework. | It remains an estimate based on assumptions, not a guarantee of actual production or profit. |
Paramount Gold Nevada’s SEC-filed 2026 Form 10-K states: “Mineral Resources that are not Mineral Reserves do not have demonstrated economic viability.” Treat that as company filing language, not a prediction about a particular investment. For a U.S. investor, check the issuer’s definitions against S-K 1300 and the project report itself; do not assume terms used across reporting regimes mean exactly the same thing.
An inferred resource cannot simply be counted as a reserve. Any later upgrade depends on further evidence and technical work, and even a higher-confidence resource category does not assure that conversion will occur.
How much weight should you give a technical study?
First identify the study’s label—an early assessment, pre-feasibility study or feasibility study—and whether a current technical report supports the public claims. A more advanced label does not remove uncertainty: a report models a project using a defined set of assumptions; it does not guarantee financing, construction, approvals or production.

Read beyond the headline net present value (NPV) or internal rate of return (IRR). Check the effective date, qualified-person sign-off, ownership interest, mine plan, metallurgy and recoveries, infrastructure, capital and operating costs, taxes and royalties, closure costs, and sensitivity analysis. Note whether the economics are pre-tax or post-tax and what discount rate is used. Look for parts of the plan that remain conceptual or depend on inferred material, and check whether the commodity prices and cost inputs are still relevant to the report date.

A positive base case is only as informative as the assumptions and downside cases that accompany it.
One project-specific example illustrates why estimate qualifiers matter: Paramount Gold Nevada’s 2026 Grassy Mountain technical report gives a feasibility-level capital-cost estimate with ±15% confidence and includes a 10% contingency. Those figures describe that estimate; they are not a universal accuracy range or contingency rule for other projects.
Can the company finance the next milestone?
A project can have an attractive modeled case and still fail to advance if its owner cannot pay for the intervening work. Compare current cash and liquid investments with corporate overhead, exploration commitments, engineering, permitting, land or option payments, debt service, and the cost and timing of the next major study or construction decision. Use the company’s stated schedule as a plan to test, not proof that it has the money or approvals to meet it.
Separate committed financing from management’s proposed or hoped-for financing. If an equity raise may be needed, model more than one issue price and calculate how the share count could change. If the plan relies on debt, a stream, royalty or joint venture, examine the security, covenants, offtake economics and project interest the company may give up. Public filings by issuers including i-80 Gold in its 2025 Form 10-K and Agnico Eagle in its 2025 annual information form and management discussion filed in 2026 identify capital requirements and access to financing among the risks to assess.
The key question is not just whether the company has cash today; it is whether funding appears sufficient to reach a clearly defined next milestone, with a credible allowance for delay and changed costs. The filings cited here do not establish a general average for shareholder dilution among pre-revenue miners, so do not treat any single company’s financing history as a sector-wide norm.
Rank #4
Which permits, rights and community issues remain?
Build a project-specific permit matrix from regulator records and the technical report. For each approval, record the responsible authority, current status, prerequisites, expiry or renewal terms, and how it affects the project schedule. A corporate timeline is not evidence that an approval has been granted.
- Land and title: Check mineral and surface rights, claims, options, royalties, access and water rights, including relevant expiry dates and obligations.
- Environmental and closure obligations: Look for baseline studies, environmental approvals, reclamation bonding, tailings plans and estimated closure liabilities.
- Community and Indigenous interests: Identify affected communities and Indigenous nations, their rights or interests, documented consultation status, agreements, unresolved objections and stated benefit-sharing commitments.
- Jurisdiction and operations: Review the applicable regulatory framework and risks tied to foreign operations, where relevant.
Paramount Gold Nevada’s 2026 Form 10-K and i-80 Gold’s 2025 Form 10-K identify permitting, environmental regulation, community protests—including those involving Indigenous groups—and conditions in foreign operations as material uncertainties. A company’s disclosure is a starting point; verify status against the relevant authority’s records and the project’s own report.

Headline contained metal is a poor shortcut for ranking pre-revenue projects. Use a consistent set of comparison points and verify that the figures have the same basis before drawing conclusions.

- It can be a gift option
- Comes with secure packaging
- Helpful in various ways
- Resource categories, reserve status and what material the study actually uses.
- Study stage, effective date, ownership interest and disclosure regime.
- Jurisdiction, permit pathway, infrastructure needs and community or Indigenous engagement.
- Metallurgy, recovery assumptions, throughput, mine life and cut-off assumptions.
- Capital intensity, operating-cost assumptions and sensitivity to prices, costs, currencies and schedule.
- Cash runway, financing commitments, obligations and fully diluted share count.
- Royalties, streams, offtake agreements, joint ventures and other claims on project value.
Ur-Energy’s 2022 annual-report discussion of S-K 1300 and NI 43-101 resource categories, alongside the later filings and reports cited above, is a reminder to check the definitions and reporting basis rather than treating similarly worded figures as interchangeable. Older reports also need scrutiny where important project inputs or plans have since changed.
Red flags to investigate before relying on the investment case
- Promotional material emphasizes inferred resources or contained metal but obscures study stage, cut-off assumptions, ownership or report date.
- A headline economic result depends on commodity-price or recovery assumptions without meaningful downside sensitivities.
- Available cash and committed funding do not appear to cover the next milestone, while company materials imply the path is fully funded.
- A permit schedule leaves out approvals, environmental work, consultation or dependencies on regulators.
- The technical report is old, important inputs have changed, or the issuer’s summary cannot be reconciled with the filed report.
These are prompts to investigate, not automatic proof that a project or company will fail. Resolve them against the underlying filings, technical report and regulator records rather than relying on promotional summaries.
What the available evidence cannot tell you
The cited material consists principally of issuer filings and project disclosures: Paramount Gold Nevada’s 2026 Form 10-K and Grassy Mountain technical report, i-80 Gold’s 2025 Form 10-K, Ur-Energy’s 2022 annual-report discussion, and Agnico Eagle’s 2025 annual information form and management discussion filed in 2026. These sources help explain disclosure and project-specific risks; they are not independent evidence of industry-wide investment outcomes.
They do not establish a general probability that a pre-revenue mining company will reach production, a typical level of shareholder dilution, or an average permitting duration. Do not substitute an anecdote or a single project’s timeline for those missing sector-wide measures. For an individual issuer, assess its newest filings, technical reports and jurisdictional permit records.
