About Denison
Denison is a uranium exploration and development company with interests focused in the Athabasca Basin
region of northern Saskatchewan, Canada. Denison has an effective 95% interest in its flagship Wheeler
River Uranium Project, which is the largest undeveloped ur anium project in the infrastructure rich eastern
portion of the Athabasca Basin region of northern Sa skatchewan. In mid-2023, a Feasibility Study was
completed for Wheeler River’s Phoenix deposit as an ISR mining operation, and an update to the previously
prepared PFS was completed for Wheeler River’s Gryphon deposit as a conventional underground mining
operation. Based on the respective studies, both deposits have the pot ential 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 have advanced significantly, with licensing in progress and a draft Environmental
Impact Statement (‘EIS’) submitted for regulator and public review October 2022.
Denison also has a large exploration portfolio and interests in various mining and development projects,
including a 22.5% ownership interest in the McClean Lake Joint Venture, which comprises several uranium
deposits and the McClean Lake uranium mill that is contracted to process the ore from the Cigar Lake mine
under a toll milling agreement, plus a 25.17% interest in the Midwest Main and Midwest A deposits and a
69.35% interest in the Tthe Heldeth Túé (“THT”) 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. Taken together, the Company has direct ownership interests in properties covering ~385,000 hectares
in the Athabasca Basin region.
Additionally, through its 50% ownership of JCU (Canada) Exploration Company, Ltd. (‘JCU’), Denison holds
further 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%).
