NexGen Energy Ltd. reported on Monday that its latest drilling campaign at the Patterson Corridor East uranium project in northern Saskatchewan has expanded high-grade mineralization by up to 94 meters vertically and 50 meters along strike.
The company’s drill hole RK-26-293 extended the vertical extent of the high-grade subdomain by 94 meters to 644 meters, intersecting uranium mineralization at a depth of 930 meters. Another hole, RK-26-290c1, intersected multiple stacked uranium veins across 40 meters, including a cumulative 19.5 meters grading over 10,000 counts per second. Within that interval, 12.9 meters contained 5.2 meters exceeding 61,000 counts per second, marking the strongest assay recorded at Patterson Corridor East to date.
A separate hole, RK-26-294, intersected 6.9 meters over 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. NexGen described both RK-26-290c1 and RK-26-294 as the two best holes drilled in 2026.
The company also reported that drill hole RK-26-296 expanded the up-dip high-grade subdomain by 50 meters along strike. The strike extent of the mineralized zone remains at 210 meters, with mineralization open in most directions, according to the company.
NexGen is accelerating exploration with the addition of a fifth drill rig to its 2026 program, which totals 42,000 meters and began on May 28, 2026. As of the latest update, 20,138.7 meters have been completed. Assays were measured using a Radiation Solutions Inc. RS-125 gamma spectrometer, though the company cautioned that total count gamma readings may not directly correlate to uranium grades.
