SASKATOON, SK, July 17, 2025 /PRNewswire/ - Orano Canada Inc. ("Orano Canada") and Denison Mines Corp. ("Denison") (TSX: DML) (NYSE American: DNN), as joint-venture partners in the McClean Lake Joint Venture ("MLJV"), are pleased to announce the successful start of uranium mining operations using the joint venture's patented Surface Access Borehole Resource Extraction ("SABRE") mining method. Orano Canada owns a 77.5% interest and is the operator of the MLJV and Denison owns a 22.5% interest. View PDF version.
SABRE mining of the McClean North uranium deposit ("McClean North") commenced in June with approximately 250 tonnes of high-grade ore (+10% U3O8) estimated to have been recovered from the first mining cavity. Orano Canada also reports that it has successfully backfilled the first cavity, advanced the SABRE rig to the planned second mining cavity, and commenced processing of the recovered ore at the McClean Lake mill.
Xavier Saint Martin Tillet, President of Orano Mining said: "The first commercial production of uranium with the SABRE technique marks a new chapter, allowing us to access and explore new territories. This innovation reinforces our commitment to delivering a reliable and responsible supply of natural uranium to nuclear power producers worldwide, supporting the generation of low-carbon electricity."
Jim Corman, Orano Canada's President and Chief Executive Officer, said, "Our long-term investment in R&D within Orano and the MLJV has culminated in the safe mining, milling and packaging of ore that in the past would have been deemed economically challenging to develop. We are pleased to be actively mining again at McClean Lake and I am so proud of the employees, contractors and partners, who have cohesively brought this mining method and project to life. It truly is an innovative and exciting time to be in the uranium industry."
David Cates, Denison's President and Chief Executive Officer, commented, "The successful commencement of SABRE mining at McClean North marks a significant milestone in the history of the MLJV, as the joint venture returns to active mining operations for the first time since 2008. Orano Canada is a world-class operator that has consistently demonstrated excellence in operation and innovation in Saskatchewan. We congratulate Orano on its leadership, long-term vision, and dedication to the development of the MLJV's SABRE mining method and ultimately the commercialization of the technology through the deployment at McClean North."
About SABRE
SABRE is the culmination of a mining equipment invention and development initiative that began in 2004 and concluded in 2021 with the completion of multi-year mining test program that successfully excavated approximately 1,500 tonnes of high-value ore. It is a non-entry, surface-based mining method that uses a high-pressure water jet placed at the bottom of a drill hole to excavate a mining cavity. The cuttings from the excavation process are then air lifted to surface, separated, and stockpiled. SABRE is viewed as an innovative mining method that has the potential to allow for access to relatively small high-grade orebodies in the Athabasca Basin that are either too small or too deep to be mined economically by conventional open-pit and/or underground mining methods.
SABRE is unique in that the mining method can be selective and scalable, which has the potential to provide superior flexibility when compared to conventional mining methods and is thus ideally suited to ever changing uranium market conditions – with an expected production ramp up of months instead of years. The SABRE method has environmental advantages when compared to conventional open pit or underground mining methods as a result of its less intrusive nature and smaller surface footprint. Reduced water usage and power consumption also contribute to important reductions in greenhouse gas emissions and improved sustainability. Additionally, as a non-entry mining method, radiological exposure for mine workers is minimized.

About Denison
Denison is a leading uranium mining, development, and exploration 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 uranium project in the infrastructure rich eastern portion of the Athabasca Basin region of northern Saskatchewan. In mid-2023, the Phoenix feasibility study was completed for the Phoenix deposit as an ISR mining operation, and an update to the previously prepared 2018 Pre-Feasibility Study ('PFS') 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 acceptance of the final form of the project's Environmental Impact Statement by the Province of Saskatchewan and the Canadian Nuclear Safety Commission.
Denison's interests in Saskatchewan also include a 22.5% ownership interest in the MLJV, which includes 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 Midwest Joint Venture Midwest Main and Midwest A deposits, and a 70.55% 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, Denison has direct ownership interests in properties covering ~384,000 hectares in the Athabasca Basin region. Additionally, through its 50% ownership of JCU (Canada) Exploration Company, Limited ('JCU'), Denison holds 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%).
In 2024, Denison celebrated its 70th year in uranium mining, exploration, and development, which began in 1954 with Denison's first acquisition of mining claims in the Elliot Lake region of northern Ontario.
