NexGen Energy said its Patterson Corridor East uranium deposit in northern Saskatchewan has expanded following recent drilling results, including two holes ranked among the best drilled so far in 2026.
Drill hole RK-26-290c1 intersected multiple stacked uranium veins over a 40-meter interval, including a cumulative 19.5 meters exceeding 10,000 counts per second. Within that zone, 12.9 meters contained a 5.2-meter section surpassing 61,000 counts per second, the highest-grade reading recorded at the site. A second hole, RK-26-294, encountered 6.9 meters above 10,000 counts per second, including 3.1 meters above 61,000 counts per second, located 27 meters along strike from a previously reported hole.
Vertical mineralization was extended by 94 meters to 644 meters in hole RK-26-293, intersecting uranium at a depth of 930 meters, a 17% increase. Lateral high-grade continuity was also expanded by 50 meters along strike in hole RK-26-296. The strike extent of the deposit remains at 210 meters, with mineralization open in most directions, the company said.
NexGen has added a fifth drill rig to its Patterson Corridor East program, which has now completed 20,138.7 meters of a planned 42,000-meter drilling campaign launched on May 28, 2026. The expanded drilling effort aims to further delineate the high-grade subdomain and assess deep-seated mineralization potential. Gamma radiation readings were measured using a Radiation Solutions RS-125 spectrometer, though the company noted these readings may not directly correlate with uranium grades.
