Keep reported plans and forecasts distinct from regulatory decisions and completed work.
What does a feasibility study prove?
A feasibility study is an integrated case for a selected project design. It can show that a particular mine and processing plan appears technically and economically viable under stated assumptions; it does not prove that the assumptions will hold, that the project is fully permitted, or that construction can begin immediately. Study maturity matters: do not treat a preliminary or initial assessment as equivalent to a feasibility study or as a final construction decision.

Check the study’s identity and maturity
- Record the study type, reporting standard, effective date, publication or filing date, and the people responsible for the technical work.
- Note the project ownership and the proposed mining method and process route. For an in-situ recovery (ISR) project, focus on the wellfield assumptions and restoration obligations; for a conventional mine, examine mine design, processing, waste, and tailings assumptions.
- Identify which resource and reserve categories support the production plan and cash flow. Do not assume every reported resource category is included on the same basis in the economic case.
- Compare the study’s scope and design with the company’s current plan. Changes to mine layout, process route, infrastructure, schedule, or production assumptions can make headline study economics a poor proxy for the project now being advanced.
Follow the economics back to their assumptions
Trace the production schedule, grade or wellfield assumptions, recovery, uranium-price case, exchange rate, royalties and taxes, initial and sustaining capital, operating costs, and closure or reclamation costs. Check the contingency and reserves, the timing of cash flows, and the sensitivity cases. Read NPV and IRR as modeled results under a defined price, tax, and discount-rate case—not as promised returns. Determine whether the figures include inferred resources or entity-level tax benefits, and whether prices are constant or nominal.
Recommended Free Tools
Compare later cost updates with the original study on a like-for-like basis. A stated inflation adjustment, estimate class, currency, contingency, and scope are important: a revised headline amount without those details cannot tell you what changed or whether the estimates are comparable.

Which permits does a uranium project need before construction?
“Permitted” is not a universal yes-or-no status. Approvals differ by jurisdiction and by the activity they authorize. An environmental assessment decision may be separate from a licence to prepare a site or construct, land and water rights, pollution-control approvals, nuclear-material authorizations, or an eventual operating authorization. A construction licence does not, by itself, establish that a mine can begin operating.
Build an approval register
For every approval, record the regulator and legal authority, decision or application date, current status, conditions, expiry or renewal requirements, and the specific activities allowed. Mark whether it is granted, conditional, appealed, in force, or pending. Also note conditions precedent: requirements that must be met before the authorization can be used or a particular activity can begin.
Rank #2
- Separate environmental assessment decisions from construction and operating authorizations.
- Track provincial, state, national, and other applicable approvals individually rather than relying on a company’s summary label.
- Identify outstanding water, land, waste, closure, or other approvals relevant to the project’s method and location.
- Check the date of every status statement. A pending decision in one company release may be resolved in a later release.
As a dated example, Denison Mines reported Saskatchewan environmental approval for Phoenix in July 2025. In a February 19, 2026 release, the company said the Canadian Nuclear Safety Commission (CNSC) had approved the environmental assessment and issued a Licence to Prepare Site & Construct a Mine and Mill. Denison described these, along with other provincial approvals it said had already been received, as the final regulatory approvals required to commence construction. That is the issuer’s account of Phoenix’s approvals at that date; it does not establish later construction progress or operating authorization.
How do I know if a uranium mine is ready to build?
Construction readiness is a chain of dependencies, not a single engineering percentage or permit milestone. Compare the feasibility design with the present execution plan and look for evidence that the remaining work has been defined, assigned, funded, and scheduled.

Assess engineering and procurement
- Check what engineering is complete and what design packages have been issued for construction. A total-completion percentage and the share of primary deliverables issued for construction measure different things.
- Separate equipment that has been ordered or contractually committed from equipment the company merely plans to procure. For long-lead items, look for delivery dates and how they fit the schedule.
- Identify construction contracts already awarded, packages still pending, contractor interfaces, and who is responsible for managing them.
- Look for a task-level schedule, commissioning and ramp-up plans, project controls, and a clear owner for contingency and cost changes.
Check financing, decisions, and remaining dependencies
Determine whether the project has funding for the planned work and whether a final investment decision (FID) has been made. A project can have substantial engineering progress and regulatory approvals while still awaiting FID, contract awards, financing, or other conditions. Check whether the schedule depends on any of those events and whether the latest capital estimate reflects the current scope.
Execution review should also cover water management, tailings or ISR restoration and closure, community commitments, and any licence conditions that remain to be satisfied. A technically mature design does not remove these obligations.
What do the Phoenix and Roughrider examples show?
The two examples below illustrate why study maturity, approval status, and execution evidence must be read separately. Their figures are project-specific company disclosures, not universal thresholds or industry benchmarks.
| Project and dated source | Study or approvals evidence | Execution or economic evidence | How to interpret it |
|---|---|---|---|
| Roughrider; November 2024 initial assessment under S-K 1300 | The assessment recommended additional data collection toward pre-feasibility work, as well as continuing permitting and project planning. | The recommendation itself points to further work; it is not a final construction decision. | Treat it as an initial assessment with project-specific recommendations, not as a final feasibility case. Its recommendations and estimates may be superseded. |
| Phoenix; Denison release dated January 2, 2026 | The company reported approximately 87% of total engineering complete and 92% of primary engineering deliverables issued for construction. | Denison reported long-lead equipment procurement, construction-contract awards still pending, a detailed schedule expected after awards and onboarding, and a Class 2 post-FID capital estimate. | These are issuer-reported progress measures at that date. They are not industry readiness thresholds, and the pending work matters to the path from design to construction. |
| Phoenix; Denison release dated February 19, 2026 | The company reported CNSC environmental assessment approval and issuance of a Licence to Prepare Site & Construct a Mine and Mill, and described these as the final regulatory approvals required to commence construction. | The release said the project could proceed with site preparation and construction activities after FID. | Read the approval milestone and the FID condition together. The release does not establish that construction was subsequently completed or that forecast costs and schedule were achieved. |
How much of the project cost is estimated versus committed?
Cost estimates are not the same as money already spent, contracted, financed, or committed. For Phoenix, Denison’s January 2, 2026 release reported an updated post-FID initial capital estimate of approximately C$600 million, in Canadian dollars, at Class 2 estimate precision. The estimate included C$65 million in contingency and owners’ reserves, which the company described as approximately 12.5% of direct and indirect project costs. Denison said the estimate was 20% above the inflation-adjusted 2023 feasibility-study estimate.

The same release reported a projected adjusted post-tax NPV of C$1.57 billion at an 8% discount rate and a projected post-tax IRR of 73% under the updated base case. These are modeled company estimates using the release’s stated price and tax assumptions, not realized returns or independent validation. Assess the cost estimate, contingency, and modeled economics on their stated bases; do not infer that the full estimate is already contractually committed or funded.
How should you compare two uranium projects?
Use the same axes and date basis for every project. A comparison of headline NPVs alone hides differences in study confidence, approval scope, cost maturity, and execution risk.
- Study: type, effective date, reporting basis, resource and reserve confidence, mining method, process route, recovery, production ramp, and design maturity.
- Economics: capital estimate class and contingency, operating and closure costs, price and exchange-rate cases, taxes, discount rate, and sensitivity to material assumptions.
- Approvals: environmental, construction, land, water, waste, nuclear, and operating decisions; conditions, appeals, expiry dates, and remaining approvals.
- Execution: engineering status, procurement commitments, long-lead delivery, contract awards, schedule detail, commissioning plan, project controls, and funded cash flow.
- Site and stakeholders: infrastructure, water and waste management, tailings or ISR restoration, community and Indigenous engagement, and ownership or joint-venture decisions.
- Outcome: schedule to first production and sensitivity to uranium prices, stated as estimates with the source date and assumptions attached.
The available project disclosures support case-by-case evaluation, not a universal scoring standard or an industry-wide claim about how often uranium-project estimates overrun.

Attribute project progress, cost estimates, and forecasts to the company that reported them, and preserve the date. For example, Denison CEO David Cates said in the company’s February 19, 2026 release: “Denison has successfully demonstrated to the Commission’s satisfaction that Phoenix can be built in a manner that meets Canada’s stringent standards.” This is the CEO’s characterization of the Commission’s decision, not an independent conclusion about construction outcomes.
For each consequential claim, ask what kind of evidence it represents: a study assumption, a company-reported progress measure, a regulator’s decision, a signed procurement or construction commitment, or completed work. Those categories answer different questions and should not be collapsed into a single “ready” label.
