About Denison Mines Corp.
Denison is a uranium mining, exploration and development company with interests focused in the Athabasca Basin region of northern Saskatchewan, Canada. The Company has an effective 95% interest in its flagship Wheeler River Uranium Project, which is the largest undeveloped uranium project in the infrastructure rich eastern portion of the Athabasca Basin region of northern Saskatchewan. In mid-2023, a feasibility study was completed for the Phoenix deposit as an in-situ recovery (âISRâ) mining operation, and an update to the previously prepared 2018 Pre-Feasibility Study was completed for Wheeler River’s Gryphon deposit as a conventional underground mining operation. Based on the respective studies, both deposits have the potential to be competitive with the lowest cost uranium mining operations in the world. Permitting efforts for the planned Phoenix ISR operation commenced in 2019 and several notable milestones were achieved in 2024 with the submission of federal licensing documents and the proposed final versions of the Environmental Impact Statement (âEISâ) to the Canadian Nuclear Safety Commission and the Province of Saskatchewan.
Denison’s interests in Saskatchewan also include a 22.5% ownership interest in the McClean Lake Joint Venture (âMLJVâ), which includes unmined uranium deposits (planned for extraction via the MLJV’s SABRE mining method starting in 2025) and the McClean Lake uranium mill (currently utilizing a portion of its licensed capacity to process the ore from the Cigar Lake mine under a toll milling agreement), plus a 25.17% interest in the MWJVâs Midwest Main and Midwest A deposits, and a 69.44% interest in the Tthe Heldeth TĂșĂ© (âTHTâ) and Huskie deposits on the Waterbury Lake Property. The Midwest Main, Midwest A, THT and Huskie deposits are located within 20 kilometres of the McClean Lake mill.
Additionally, through its 50% ownership of JCU (Canada) Exploration Company, Limited (âJCUâ), Denison holds additional interests in various uranium project joint ventures in Canada, including the Millennium project (JCU, 30.099%), the Kiggavik project (JCU, 33.8118%), and Christie Lake (JCU, 34.4508%).
Denisonâs exploration portfolio includes further interests in properties covering ~384,000 hectares in the Athabasca Basin region.
In 2024, Denison celebrated its 70th year in uranium mining, exploration, and development, which began in 1954 with Denisonâs first acquisition of mining claims in the Elliot Lake region of northern Ontario.
