[{"type":"text","content":"NexGen Announces New Significant High Grade Assay Results at Patterson Corridor EastVancouver, British Columbia--(Newsfile Corp. - November 12, 2025) - NexGen Energy Ltd. (TSX: NXE) (NYSE: NXE) (ASX: NXG) (\"NexGen\" or the \"Company\") is excited to announce significant geochemical assay results from NexGen's 100%-owned Patterson Corridor East (\"PCE\") discovery. Drillhole RK-25-254 returned 10.5 meters (\"m\") at 11.3% U3O8 including 4.0m at 29.4% U3O8 and 0.5m at 56.2% U3O8 (Figures 1 and 2, Table 1). Notably, mineralization in RK-25-254 is 55m up dip from hole RK-25-232 which intersected 15.0m at 15.9% U3O8 including 3.0m at 47.8% U3O8, 1.5m at 29.4% U3O8 and an intercept of 0.5m at 68.8% U3O8 (see May 27, 2025 news release).Drillhole RK-25-244, 19m down dip of RK-25-232, returned equally strong results, 17.0m at 7.6% U3O8 including 6.0m at 21.1% U3O8 and 0.5m at 58.1% U3O8 (Figures 1 and 3, Table 1). Additional assay results contained in this release, confirm strong continuity of the high-grade subdomain (Figure 1, Table 1) over 330m in vertical extent from RK-25-246 to RK-25-231. Further, RK-25-231 (8.0m at 1.4% U3O8) and -241 (8.5m at 1.3% U3O8) demonstrate the continuity of the subdomain and add breadth while indicating extended high-grade potential. A secondary high-grade subdomain is currently interpreted from results in RK-25-234, with 0.5m at 8.3% U3O8 that lies along a potential new high-grade shoot. Note, additional assay results from drillhole RK-25-256, which intersected intense high-grade mineralization 128m down dip of RK-25-232 and 179m from RK-25-254, are pending and will be released with further assays as they are received back from the independent lab.PCE drilling has delivered significant advancements of a discovery that is characteristic of the southwest Athabasca Basin district, of which NexGen holds a 190,000 hectare land package. This setting has an identical technical advantage as the nearby Arrow deposit, 3.5 kilometers (\"km\") west of PCE, as mineralization is fully hosted in competent basement rock with dimensions that are expanding rapidly since initial discovery in February 2024. The overall mineralized footprint is currently defined as 600m along strike and 600m of vertical extent, with a high-grade subdomain of 210m in strike and 335m in vertical extent.
