Exciting Uranium Discoveries at Denison's McClean South Zone
Denison Mines Corporation Unveils New Uranium Discoveries
Denison Mines Corp. is thrilled to announce the discovery of multiple high-grade uranium mineralization intercepts at McClean South, part of its 22.5%-owned McClean Lake Joint Venture. This remarkable exploration success will contribute significantly to the company's ongoing operations in uranium mining.
Details of the Exploration Program
The uranium exploration program at McClean South has been pivotal in confirming and expanding the mineralized footprint within this area. With a recent drilling program covering 6,400 meters, the results yielded several notable high-grade intersections, especially at the 8C mineralized pod. Significant findings include:
- MCS-77: 7.51% eU3O8 over 5.4 meters from 165.7 to 171.1 meters (including intervals of 10.88% eU3O8 over 3.7 meters).
- MCS-80: 3.5% eU3O8 over 11.2 meters from 156.7 to 167.9 meters.
- MCS-84: 1.72% eU3O8 over 20.6 meters from 150.6 to 170.7 meters.
A total of fourteen out of twenty-four drilled holes encountered significant uranium mineralization, further validating the continuity of resources in the 8C and 8W pods.
Importance of the McClean South Discovery
Located just 600 meters south of the McClean North deposit, which has commenced commercial mining recently, McClean South is illustrated as a promising area for future operations. The company’s exploration initiatives, operated to expand the footprint of high-grade mineralization in the 8C and 8W pods, have been fruitful.
Statements from Denison Leadership
Vice President of Technical Services and Project Evaluation, Chad Sorba, expressed enthusiasm about the exploration results, emphasizing collaboration with Orano Canada in further delineating high-grade intercepts, thereby extending the mineralized footprint. Denison's President & CEO, David Cates, congratulated Orano Canada on this success and highlighted the potential for McClean South to become an economic resource feeding the nearby McClean Lake mill.
Exploration Highlights for 2025
The 2025 exploration program aimed at expanding the known high-grade mineralization, with results demonstrating mineralization above 0.05% eU3O8 in numerous drill holes. The findings from the 8W pod, particularly, confirmed mineralization at shallow depths near the western edge. Drill holes MCS-61 and MCS-64 yielded promising results, showcasing a continuous resource, vital for future extraction.
Technical Details and Procedures
The drilling process at Denison involves radiometric logging with a slimline gamma probe, which accurately records radioactivity in the drilled holes. The correlation between gamma-log results and geochemical analyses allows for precise mineral evaluations. Sample collection follows stringent protocols, ensuring rigorous assessment of mineral quality and yield.
Exploration and Mining Development at McClean Lake
The McClean Lake Project hosts nine known uranium deposits, and Denison continues to hold a significant interest in operations through the MLJV with Orano Canada. This partnership is crucial for ongoing operations and upcoming mining endeavors at various deposits.
Denison Mines: A Leader in Uranium Production
Denison is a prominent player in uranium mining and exploration, particularly in the Athabasca Basin region. With a 22.5% share in the McClean Lake Joint Venture, the company is poised for substantial growth and contribution to the uranium market, especially with the promising developments at McClean South.
