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.

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.
