Full summary

NexGen Energy Ltd. announced the results from the early portion of 2026 summer drilling at the Patterson Corridor East (PCE), which expanded the high-grade subdomain both up and down dip. The vertical extent of the high-grade subdomain increased by 17% to 644 m. Hole RK-26-293 intersected cumulative 4.7 m of >10,000 cps, including 0.1 m of >61,000 cps at 930 m depth, significantly expanding the known mineralized footprint. Additionally, hole RK-26-290c1 intersected multiple stacked uranium veins across 40 m of the high-grade subdomain with cumulative 19.5 m of >10,000 cps, including 12.9 m of >10,000 cps surrounding 5.2 m of >61,000 cps. NexGen has added a fifth drill rig to continue advancing the discovery optimally.
