Denison Mines Moves Forward with Phoenix ISR Uranium Mine Construction Starting March 2026

Denison Mines Advances Phoenix ISR Uranium Mine Construction

Denison Mines Corp. has announced a pivotal development in its operations with the Final Investment Decision (FID) for the Phoenix In-Situ Recovery (ISR) uranium mine. This decision marks a significant milestone not only for Denison but also for the broader Canadian uranium mining sector. The company plans to initiate construction activities in March 2026, bolstering its position within a market that increasingly prioritizes sustainable and responsible uranium sourcing. David Cates, President and CEO of Denison, emphasizes that this decision is groundbreaking, representing years of dedicated effort to prepare the Phoenix project for development. The project has successfully navigated the complex landscape of obtaining both provincial and federal approvals, a crucial step that enhances its sustainability and regulatory compliance.

The Phoenix mine, strategically located within the Wheeler River Project in the eastern Athabasca Basin of Saskatchewan, is notable for being the largest undeveloped uranium project in the region. This mine, once operational, will position Denison among a select group of global uranium suppliers, capable of contributing significantly to the world’s uranium production by the end of the decade. The Phoenix site hosts high-grade uranium deposits, which Denison initially discovered in 2008, showcasing the company’s leading role within the industry. The construction phase is expected to last approximately two years, with production set to commence by mid-2028. Such timelines indicate Denison’s commitment to not only advancing its projects but also addressing growing demands in the nuclear energy sector.

Furthermore, Denison holds a 90% stake in the joint venture for the Wheler River Project, while JCU (Canada) Exploration Company Limited retains the remaining 10%. This strategic partnership allows Denison to maintain operational control while sharing resources and risks associated with one of the most promising uranium projects globally. Complementing the recent FID, Denison’s August 2023 technical report on the Phoenix mine feasibility study provides further insights into the operational and financial aspects of the project. These developments position Denison Mines as a proactive player, well-prepared to navigate the current landscape of uranium supply and demand.

In summary, Denison Mines’ decision to move forward with the construction of the Phoenix ISR uranium mine marks a crucial step toward establishing a significant source of uranium production in line with the growing global appetite for nuclear energy. With the framework already in place and construction imminent, Denison is poised to make its mark on the uranium industry, contributing to sustainable energy solutions for the future.
