NEW YORK, January 1, 2026, 07:08 ET — Market closed.
- Denison Mines closed Wednesday up about 1% at $2.66, ahead of the New Year’s Day U.S. market holiday.
- Uranium ended Dec. 31 at $81.65 a pound; prices were up nearly 7% over the past month, Trading Economics data showed.
- Traders head into Friday’s reopening watching uranium prices, nuclear-fuel supply-chain headlines, and Denison’s next corporate update.
Denison Mines Corp shares rose about 1% to $2.66 in the last U.S. trading session of 2025, with markets closed on Thursday for New Year’s Day.
That modest move still matters in uranium-linked stocks because investors finished the year with the spot uranium price holding above $80 a pound, keeping the sector sensitive to commodity signals and nuclear policy headlines.
Denison is a developer rather than a producer, so its shares often act as a proxy for long-term uranium prices and project progress, not near-term cash flow.
Uranium ended Dec. 31 at $81.65 per pound, down 0.24% on the day but up 6.87% over the past month, Trading Economics data showed. The same source’s model implied uranium near $83.91 per pound by the end of the quarter.
In the futures market, the front-month UxC uranium contract was around $81.85 per pound, CME Group quotes showed.
Nuclear fuel-chain headlines were also in focus. Urenco USA said it completed an initial production run enriching uranium to 8.5% U-235 and plans to begin commercial production of LEU+ — uranium enriched between 5% and 10% — in mid-2026, while expanding capacity measured in SWU (separative work units) by 2027. “We are the only domestic supplier of enriched uranium,” said Jeremy Derryberry, Urenco USA’s director of communications.

Denison, based in Canada, focuses on uranium exploration and development in Saskatchewan’s Athabasca Basin. It holds a 95% interest in the Wheeler River project, which hosts the Phoenix and Gryphon deposits, and also owns stakes in the McClean Lake joint venture and other exploration assets, a Reuters company profile shows.
At Wheeler River, Denison has outlined plans for Phoenix using in-situ recovery (ISR), a method that circulates a mining solution through underground ore and pumps uranium-bearing fluid back to the surface for processing.
The setup leaves Denison’s stock especially reactive to uranium-price momentum, shifts in risk appetite for smaller miners, and signs that the nuclear build-out is translating into tighter fuel-cycle capacity and contracting.
Investors in the group also keep an eye on larger uranium names such as Cameco and other North American-focused miners for market signals on contracting activity, even when smaller developers have no fresh company-specific news.
Before the next session on Friday, chart watchers will likely key off the stock’s position within its 52-week range of $1.08 to $3.42, according to Investing.com data.
Denison’s investor calendar lists reporting dates through its third-quarter 2025 results and notes dates are subject to change; it does not yet show a reporting date for the next quarter.
