Vancouver, British Columbia–( – April 22, 2026) – NexGen Energy Ltd. (TSX: NXE) (NYSE: NXE) (ASX: NXG) (“NexGen” or the “Company”) announces results from the 2026 winter drill program at Patterson Corridor East (“PCE”) that recently concluded, highlighting significant vertical growth and strong internal continuity of high-grade mineralization.
Within the mineralized zone of PCE, the high-grade subdomain has now grown to 550 m in vertical extent, a 33% increase, with a strike length of 210 m. This expansion was primarily driven by hole RK-26-280c1 which returned cumulative 4.2m of >10,000 cps including 0.6m of >61,000 cps at 834m below surface (Figures 1-3). The hole successfully intersected mineralization 230m down plunge along a high-grade shoot interpreted to connect with RK-26-271c1 (Figure 4).
Holes RK-26-271c1, RK-26-276, and RK-26-285 returned strong mineralized intercepts between 600 to 700m below surface, where the system remains open for expansion (Figures 1 and 2, Table 1). Results from RK-26-271c1 include cumulative 12.6m of >10,000 cps including 2.3m of >61,000 cps 80m down plunge of RK-25-256 (5.5m at 21.4% U3O8) indicating continuity of intense high-grade mineralization (Figure 3). Further, the intersections from RK-26-276 (cumulative 11.2m of >10,000 cps including 0.6m of >61,000 cps) and RK-26-285 (cumulative 9.0m of >10,000 cps including 0.7m of >61,000 cps) add progressive high-grade continuity to the base of this growing subdomain.
Drilling 600m to the southeast of PCE along a separate parallel trend, prospective structure and alteration features are vectoring the Company toward potential repetition of mineralization within the overall PCE system (Figure 5).
Summer drilling of ~29,200m is schedule to commence the week of May 25, 2026. All samples from 2026 drilling are submitted to the independent Saskatchewan Research Council Geoanalytical Laboratory (SRC), with results to follow.
Leigh Curyer, Founder & Chief Executive Officer, commented: “Today’s results from the 2026 winter program confirm both the scale and growth of PCE continues to advance at pace. 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. In parallel, drilling focused on vectoring into additional zones of mineralization will be incorporated into the summer program based on these winter results.
“With the Rook I Project commencing construction this summer and the significance of PCE materializing rapidly, we look forward to future drilling and evaluation of PCE and its potential position in the long-term profile of NexGen’s uranium portfolio. NexGen is positioned to meet the strong demand for Canadian uranium for many decades into the future, whilst setting a new industry standard in the safe, efficient and reliable delivery of offtake to utility customers around the world.”
A total of 12,758.2m of the planned 42,000m has been completed in 2026, focusing on high-grade growth and expansion of mineralization. Thirteen drill holes totalling 9,131.7m were dedicated to advancing the mineralization at PCE and six drill holes totalling 3,626.5m tested the parallel trend. Since discovery (see news release date March 11, 2024), 115 drillholes totalling 72,464.7m targeted PCE mineralization (Figure 4) with 79 of the 115 drill holes being mineralized, including 54 intersecting high-grade (>10,000 cps) and 21 intersecting off-scale (>61,000 cps).
