NexGen’s Final Batch of 2025 Assays Return Multiple High-Grade Intercepts
Press Release
Confirming Both Expansion and Continuity of Primary High-Grade Subdomain and Confirmation of New High-Grade Subdomain at Depth
Highlights:
- RK-25-239 returns 13.0 m at 5.2% U3O8, including 0.5 m at 30.2% U3O8 confirming expansion of the growing high-grade subdomain 33 m up dip of RK-25-232 (15.0 m at 15.9% U3O8)
- RK-25-240 returns 10.0 m at 3.95% U3O8, including 0.5 m at 33.3% U3O8 in the down dip portion of the high-grade subdomain 266 m below RK-25-232
- Assays from RK-25-230 (7.5 m at 5.3% U3O8 including 0.5 m at 35.9% U3O8), RK-25-233 (6.0 m at 2.4% U3O8 including 0.5 m at 23.4% U3O8), RK-25-236 (5.5 m at 2.3% U3O8 including 0.5 m at 13.3% U3O8) confirm continuity of high-grade subdomain; 47 m, 151 m, and 40 m respectively from RK-25-232
- Confirmed the new high-grade subdomain, at 850 m below surface with RK-25-257 returning 4.5 m at 4.8% U3O8 including 0.5 m at 33.3% U3O8 located 67 m up dip of RK-24-202 (0.5 m at 6.9% U3O8). Confirms significant growth potential.
Vancouver, British Columbia–( – May 7, 2026) – NexGen Energy Ltd. (TSX: NXE) (NYSE: NXE) (ASX: NXG) (“NexGen” or the “Company”) announces the final receipt of 2025 assay results that highlight the expansion and continuity of the high-grade subdomain at the Company’s 100% owned Patterson Corridor East (PCE) discovery located 3.5 km from the Arrow Deposit. The expansion of the high-grade subdomain is especially confirmed by RK-25-239 which returned 13.0 m at 5.2% U3O8, including 0.5 m at 30.2% U3O8, at 400 m below surface and RK-25-240 which returned 10.0 m at 3.95% U3O8, including 0.5 m at 33.3% U3O8, at 670 m below surface. Both of these holes share strong similarities with respect to their overall geological characteristics which span across 292 m of mineralized dip extent. (Figures 1-3, Table 1).
Results from RK-25-240 emphasize the potential extension of mineralization at depth where the system is open. Together with these results, the grades from RK-25-230 (Figure 4), RK-25-233, RK-25-236 have confirmed a strong core zone within the high-grade subdomain which remains open in most directions.
Within the overall mineralized footprint, a new secondary high-grade subdomain is now confirmed by RK-25-257 (Figures 1 and 5). This hole has several intercepts with the best being 4.5 m at 4.8% U3O8 including 0.5 m at 33.3% U3O8 located 67 m up dip of RK-24-202 (0.5 m at 6.9% U3O8). This new subdomain has high prospectivity for continued growth and is open in most directions.
Exploration drilling in 2026 has already driven further growth at PCE with the majority of the campaign (29,241.8 m of the planned 42,000 m) scheduled to recommence the week of May 25, 2026 (see news release April 22, 2026). All samples from 2026 drilling to date are submitted to the independent Saskatchewan Research Council Geoanalytical Laboratory (SRC), with results to follow.
Leigh Curyer, Founder & Chief Executive Officer, commented: “These assay results from 2025 drilling confirm high-grade mineralization and the expanding scale of PCE. The combination of high-grades, continuity, scale and geotechnical characteristics continue to highlight the similarities between PCE and the mighty Arrow Deposit. The opening up of a new high-grade subdomain emphasizes significant growth potential remains at PCE. With the structural supply deficit in the market widening, and the impacts of the industry wide underinvestment in the uranium supply chain for a generation, the urgency of finding and bringing online new, reliable uranium supply has never been greater. As the Rook I Project enters into major construction this summer, we continue to advance PCE to ensure that NexGen optimizes its unparalleled opportunity to become one of the world’s most important mining company in delivering energy fuel for the current and future generations.”
