NexGen Energy Ltd. (“NexGen” or the “Company”) (TSX: NXE) (NYSE: NXE) (ASX: NXG) is excited to announce the commencement of a 43,000 meter (m) exploration drill program to continue to test the extents and growth of mineralization discovered in early 2024 at Patterson Corridor East (PCE) located 3.5 km east of the world-class Arrow Deposit. This systematic program represents an increase of 9,000 m from the 2024 program and is expected to be one of the largest drill programs in the Athabasca Basin, Saskatchewan in 2025. The initial results at PCE revealed vein-type uranium mineralization intersected within the competent basement rock, highly analogous to Arrow. Since discovery, the mineralized footprint at PCE has rapidly grown to 600 m along strike and 600 m of vertical extent (see November 12, 2024 news release). read more

NexGen Announces Best Hole to Date (RK-24-222) and High-Grade Expansion at Patterson Corridor East Concluding a Successful 2024 Drilling Program

NexGen’s 2024 exploration campaign delivered a new discovery on Rook I at Patterson Corridor East (“PCE”) 3.5km east of Arrow. Subsequent drilling has materially expanded the mineralized zone to 600 m strike length and 600 m vertical extent with 19 of 30 holes intersecting mineralization including 10 holes with multiple intervals >10,000 cps. Today’s announcement highlights the best hole to date at PCE (RK-24-222) returns 17.0 m wide vein with multiple high intensity (>61,000 cps) occurrences. In 2024, PCE is the largest drill program in the Athabasca Basin by any Company at 34,000 meters (m).

NexGen Energy Ltd. (“NexGen” or the “Company”) (TSX: NXE) (NYSE: NXE) (ASX: NXG) is proud to announce the completion of its 2024 drilling campaign at Patterson Corridor East (PCE) that included more than 34,000 m across a total of 46 drillholes. Upon initial discovery of intense uranium mineralization at PCE (see March 11 News Release), the Company directed all drilling activity to focus exclusively on PCE, whereby 19 of 30 holes intersected mineralization. Bold and systematic spacing of drillhole intercepts have quickly grown the discovery from a single hole to a broad and continuous new uranium discovery. Real-time evaluation of results throughout the duration of the program focused on determining the overall outer extents of the mineralized zone and in parallel, precisely targeting high-grade sub-domains (Figures 1 and 2, Table 1). read more
