Denison Mines (NYSE: DNN) has announced significant new discoveries of high-grade uranium mineralization at the McClean South zone, part of its 22.5%-owned McClean Lake Joint Venture in Saskatchewan. The 6,400-metre exploration program, conducted by majority owner Orano Canada (77.5%), revealed multiple high-grade intersections at the 8C pod, including:
- MCS-77: 7.51% eU3O8 over 5.4 metres
- MCS-80: 3.5% eU3O8 over 11.2 metres
- MCS-84: 1.72% eU3O8 over 20.6 metres
The program successfully expanded the mineralized footprint of the 8C and 8W pods, with 14 out of 24 drill holes encountering significant uranium mineralization. McClean South is located approximately 600 metres from the McClean North deposit, which recently began commercial production using the SABRE mining method.
Denison Mines (NYSE: DNN) and Orano Canada have successfully launched uranium mining operations using their patented Surface Access Borehole Resource Extraction (SABRE) method at the McClean Lake Joint Venture.

The joint venture, in which Orano Canada holds a 77.5% interest as operator and Denison owns 22.5%, has already completed backfilling of the first cavity and begun processing the recovered ore at the McClean Lake mill. This marks the first active mining operations at the site since 2008, representing a significant technological advancement in uranium mining capabilities.
