NexGen Energy Ltd. (TSX: NXE) announced a 33% increase in the vertical extent of its high-grade uranium subdomain at the Patterson Corridor East (PCE) discovery, following the completion of its 2026 winter drill program. The high-grade zone now extends to 550 meters vertically with a strike length of 210 meters, signaling a major expansion of the mineralized system.
"Today's results from the 2026 winter program confirm both the scale and growth of PCE continues to advance at pace," said Leigh Curyer, Chief Executive Officer of NexGen. "Increasing the vertical extent of the high-grade subdomain by 33% during the winter program, suggests substantial drilling is required going forward to fully understand the extent of this mineralized zone."
The expansion was driven by significant intercepts across multiple drill holes. Hole RK-26-280c1 extended the high-grade zone, intersecting a cumulative 4.2 meters of mineralization greater than 10,000 counts per second (cps), including 0.6 meters of "off-scale" radioactivity exceeding 61,000 cps. Hole RK-26-271c1 confirmed the continuity of intense mineralization, returning 12.6 meters of >10,000 cps, including 2.3 meters of off-scale material.
The results provide strong evidence for a growing, high-grade uranium system at PCE, located at the company's Rook I property in Saskatchewan, Canada. The Rook I project is slated to become one of the largest low-cost uranium mines globally. The continued success at PCE could materially add to the project's resource base, which is not far from Cameco Corp.'s Cigar Lake, one of the highest-grade uranium mines in the world.
The winter program completed 12,758.2 meters of a planned 42,000-meter drill program for 2026. Key results include:
Since its discovery in March 2024, 115 holes have been drilled at PCE, with 79 intersecting mineralization. Of those, 54 hit high-grade material and 21 encountered off-scale radioactivity.
NexGen plans to commence a summer drilling program of approximately 29,200 meters the week of May 25, 2026, to further delineate the expanding mineralized zone. All samples are being sent to the Saskatchewan Research Council Geoanalytical Laboratory for assay results.
