Denison Mines Corp’s U.S.-listed shares (DNN) ended Friday at $3.03, up 13.9%, after a company update on its flagship Phoenix uranium project. The stock traded between $2.74 and $3.07 and posted about 68.3 million shares of volume. Yahoo Finance
The move matters because Denison is trying to shift from years of engineering and permitting into a build phase. For a pre-production miner, the market often prices permit momentum more heavily than quarterly noise.
Cost discipline is also front and center for uranium developers as inflation pressure shows up in capital budgets. Friday’s reaction suggested investors were willing to look past a higher headline price tag if the schedule holds.
Denison said it is ready to make a final investment decision and begin construction of the proposed Phoenix in-situ recovery mine at its Wheeler River property, once it receives final regulatory approvals. The company said it is targeting mid-2028 first production, assuming approvals to commence construction arrive in the first quarter of 2026. SEC
A final investment decision is management’s formal go-ahead to commit major capital spending. In-situ recovery, or ISR, uses wells to circulate a solution through the ore zone and pump uranium-bearing fluids back to the surface, avoiding a conventional open-pit or underground mine.
Denison said Phoenix post‑FID initial capital costs are expected to be about $600 million, which it described as a construction “control budget,” and said the update reflects inflation adjustments, project refinements and tighter estimating as engineering and procurement advanced. It also said the project’s base-case adjusted after-tax net present value at an 8% discount rate was about $1.57 billion and the post-tax internal rate of return was 73% under its updated assumptions.

The company said it had more than $700 million of cash, physical uranium and investments as of Sept. 30, and that the procurement process for planned 2026 construction contracts was nearly complete, with awards expected in early 2026. SEC
“Phoenix … is now ready to become the first new large-scale uranium mine built in Canada since Cigar Lake,” President and CEO David Cates said. SEC
Uranium-linked stocks rallied broadly on Friday, helping lift Canada’s main index, Reuters reported, with Denison’s Toronto-listed shares up 13.7% and Energy Fuels gaining 15.4%. Uranium was around $81.65 a pound on Jan. 2, according to Trading Economics. Reuters
Before the next session, investors are watching for a decision from Canada’s nuclear regulator following a public hearing that Denison said concluded on Dec. 11, along with any clarity on when the company can move to a final investment decision. Denison has said the key swing factor is receiving final approvals in time to keep a mid-2028 first-production target intact. PR Newswire
Technically, DNN is sitting near the top of its Friday range ($2.74–$3.07) and below a 52‑week high of $3.42, according to Investing.com data. The $2.66 prior close is the nearest reference point if momentum cools. Investing
Macro events could also set the tone for risk appetite in the week ahead: the U.S. employment report for December is due Jan. 9 at 8:30 a.m. ET, followed by the Jan. 13 consumer price index, according to a Reuters Week Ahead preview and the Bureau of Labor Statistics schedule. Rate-sensitive swings can spill over into commodity-linked equities, including uranium miners. Reuters
