Peter Ballantyne Cree Nation Withdraws Judicial Review and Confirms Support for the Wheeler River Project

Denison Mines Corp. (DML) announced that the Peter Ballantyne Cree Nation (PBCN) has withdrawn its judicial review application regarding the Environmental Assessment (EA) approval for the Phoenix In-Situ Recovery (ISR) uranium mine. In conjunction with this withdrawal, PBCN has formally provided consent and support for the development and operation of Denison's Wheeler River Project in northern Saskatchewan.
The Wheeler River project, a joint venture between Denison Mines (90% interest, operator) and JCU (Canada) Exploration Company Limited (10% interest), includes the high-grade Phoenix and Gryphon deposits. Site preparation and early works construction for Phoenix commenced in March 2026, with first production targeted for 2028. The project received EA approval from the Province of Saskatchewan in July 2025 and construction license approval from the Canadian Nuclear Safety Commission in February 2026.
The project is based on the August 2023 NI 43-101 Technical Report, which includes the Phoenix Feasibility Study and a cost update to the 2018 Pre-Feasibility Study for the Gryphon deposit. Both deposits are assessed as having the potential to be competitive with the lowest-cost uranium mining operations globally. An update to estimated Phoenix initial capital costs was disclosed in a press release dated January 2, 2026.
Regarding the community relationship, Denison stated: "As a result of further engagement with PBCN, Denison is also pleased to report that PBCN has now formally provided its consent to and support for the development and operation of Denison's Wheeler River Project ("Wheeler River") in northern Saskatchewan."
Beyond the Wheeler River project, Denison holds a 22.5% interest in the McClean Lake Joint Venture (MLJV), where mining at McClean North commenced in 2025, and a 25.17% interest in the Midwest Joint Venture. Denison also holds interests in the Millennium, Kiggavik, and Christie Lake projects through its 50% ownership of JCU.
