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. 1
- Uranium ended Dec. 31 at $81.65 a pound; prices were up nearly 7% over the past month, Trading Economics data showed. 2
- Traders head into Friday’s reopening watching uranium prices, nuclear-fuel supply-chain headlines, and Denison’s next corporate update. 3
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. 1
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. 2
In the futures market, the front-month UxC uranium contract was around $81.85 per pound, CME Group quotes showed. 4
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. 5
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. 6
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. 7
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. 8
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. 3
