Denison Mines Corp. reported its 2025 operational results and confirmed a final investment decision to build the Phoenix in-situ recovery uranium mine at its Wheeler River project. Construction is expected to start in March 2026 and take about two years, targeting first production by mid-2028.
The company received final federal regulatory approval from the Canadian Nuclear Safety Commission and awarded a construction management contract to Wood Canada Limited. An updated Class 2 initial capital estimate puts post-FID costs for Phoenix at approximately $600 million, supported in part by a completed US$345 million convertible senior notes offering due on September 15, 2031.
Denison also advanced other assets: the McClean North SABRE mine produced 648,558 pounds U3O8 in 2025 at operating cash costs near $36 per pound, and a preliminary economic assessment for the Midwest project outlined potential production of 37.4 million pounds U3O8 with an after-tax NPV of $965 million and IRR of 82.7%.
Denison Mines Corp. filed its annual consolidated financial statements, showing total assets rising to $1,106,074,000 at December 31, 2025 from $663,613,000 a year earlier, mainly driven by cash and investments in uranium and new financing.
Revenue from continuing operations increased modestly to $4,918,000, but the net loss widened sharply to $217,288,000 from $91,119,000, largely due to finance expense tied to new Convertible Senior Unsecured Notes. Cash and cash equivalents climbed to $465,918,000, and the company held physical uranium valued at $190,276,000 after selling 500,000 pounds during 2025. KPMG LLP issued unqualified opinions on both the financial statements and the effectiveness of internal control over financial reporting.
Denison Mines Corp. has filed a Form 6-K to share a press release announcing its Board’s Final Investment Decision to build the Phoenix in-situ recovery uranium mine at the Wheeler River project in Saskatchewan, with site preparation and construction planned to start in March 2026.
Construction is anticipated to take about two years, with an objective of achieving first uranium production from Phoenix by mid-2028. Phoenix is part of Wheeler River, described as the largest undeveloped uranium project in the eastern Athabasca Basin, where Denison holds a 90% operating interest alongside JCU’s 10% stake.
Denison Mines Corp. has scheduled its Annual General Meeting of security holders for May 12, 2026 in Toronto. The record date for notice of meeting, voting, and beneficial ownership determination is March 24, 2026, meaning holders on that date are entitled to receive materials and vote.
The company will use notice-and-access for both registered and beneficial holders, without stratification criteria. Proxy-related materials will not be sent directly to non-objecting beneficial owners, but Denison will pay for delivery to objecting beneficial owners. The meeting concerns holders of its common shares.
Denison Mines Corp. reports that the Canadian Nuclear Safety Commission has approved the Environmental Assessment and issued the Licence to Prepare Site & Construct a Mine and Mill for the Wheeler River Phoenix in-situ recovery (ISR) uranium project in Saskatchewan. With prior provincial approvals already in place, this represents the final regulatory clearance needed to start construction of the Phoenix uranium mine.
Phoenix is described as the first uranium mine in Canada approved for ISR mining and the first large-scale Canadian uranium mine approved for construction in more than 20 years. Denison targets an approximately 2-year construction period and indicates the project remains on track for first production by mid-2028, subject to a final investment decision. The company notes it has advanced pre-construction work so it can move quickly once that decision is made.
Denison Mines Corp. has awarded a construction management contract to Wood Canada Limited to oversee building the Phoenix in-situ recovery uranium mine at the Wheeler River project in Saskatchewan. The deal follows a competitive tender and deepens an existing engineering partnership between the companies.
The contract covers procurement and construction management for the processing plant, installation of key site infrastructure, and integrated project controls, safety oversight, and reporting. Denison expects an estimated 24‑month construction period and indicates it is prepared to make a final investment decision and start construction after securing remaining Federal permits.
Wheeler River, where Denison is operator with a 90% joint‑venture interest, hosts the high‑grade Phoenix and Gryphon deposits and is described as the largest undeveloped uranium project in the eastern Athabasca Basin. Provincial environmental assessment approval was received in July 2025, and a Canadian Nuclear Safety Commission public hearing on Federal approvals concluded in December 2025.
Denison Mines Corp. received an amended ownership report showing that Van Eck Associates Corporation beneficially owns 76,290,047 common shares, representing 8.51% of the class as of 12/31/2025. Van Eck reports sole voting and dispositive power over these shares.
