Denison Announces Additional High-Grade Uranium Mineralization Discovered at McClean South

Core Viewpoint - Denison Mines Corp. has announced significant new intercepts of high-grade uranium mineralization at the McClean South zone, part of the McClean Lake Joint Venture, indicating potential for economic development in the area [1][3][12]. Exploration Results - A total of 14 out of 24 completed drill holes encountered significant uranium mineralization, confirming and expanding the mineralized footprint of the 8C and 8W pods [2][4]. - The exploration program aimed to expand the existing footprint of high-grade mineralization, with uranium mineralization greater than 0.05% eU (0.06% eU3O8) intersected in 14 of the 24 drill holes [4]. Notable Drill Results - Drill hole MCS-77 intersected 7.51% eU3O8 over 5.4 meters, including 10.88% eU3O8 over 3.7 meters [6]. - Drill hole MCS-80 intersected 3.5% eU3O8 over 11.2 meters, including 5.81% eU3O8 over 6.5 meters [6]. - Drill hole MCS-84 intersected 1.72% eU3O8 over 20.6 meters, including 4.43% eU3O8 over 4.0 meters [6]. Project Context - The McClean South zone is located approximately 600 meters south of the McClean North deposit, which has recently commenced commercial mining using the SABRE mining method [2][12]. - Denison holds a 22.5% ownership interest in the McClean Lake Joint Venture, which includes one of the world's largest uranium processing facilities with a licensed annual production capacity of 24 million pounds U3O8 [12][15]. Future Potential - The successful exploration results at McClean South may position it as a new economic source of future feed to the McClean Lake mill, especially with advancements in the In-Situ Recovery (ISR) mining method [3][12].
