Rhea-AI Summary

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%.

Rhea-AI Summary

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.
