NexGen Announces Expansion of High-Grade Subdomain at Patterson Corridor East (PCE) and Commencement of 2026 Exploration Program Totalling 45,500 Meters

Core Insights - NexGen Energy Ltd. has reported significant expansion of mineralization at the PCE site, with a vertical extent increase of 23% from 335 m to 412 m and a strike length of 210 m [1][3]. - The overall mineralized footprint has expanded to 700 m in vertical extent and 620 m in strike length, indicating ongoing growth potential [1][4]. - The 2026 drilling program will involve 42,000 meters of diamond drilling, marking the largest program to date at the PCE discovery [1][12]. PCE Expansion - The vertical extent of the high-grade subdomain has increased by 23% from 335 m to 412 m, with a strike length of 210 m [1][3]. - The mineralized footprint has expanded to 700 m vertical extent (up from 600 m) and 620 m strike length (up from 600 m) [1][4]. - Additional high-grade subdomain development is noted at 850 m below the surface, indicating further growth potential [1]. 2025 Drilling Program Results - The final drill holes of the 2025 PCE program showed continued expansion of mineralization, with the primary high-grade subdomain growing to 412 m in vertical extent and a strike length of 210 m [3][6]. - A total of 35,366.2 m of drilling was completed in 2025, the largest reported in the Athabasca Basin for that year [6]. - Of the 102 drill holes completed since discovery, 67 are mineralized, with 45 intersecting high-grade (>10,000 cps) and 17 intersecting off-scale (>61,000 cps) [6]. 2026 Exploration Program - The 2026 program will focus on high-grade growth and the continued expansion of the mineralized footprint, with at least eight 200 m spaced tests planned [12]. - Inaugural drilling at NexGen's 100% owned SW3 property will involve 3,500 m to advance high-priority targets [2][14]. - The 2026 program aims to systematically advance PCE while also exploring for repetition of mineralization within the same hydrothermal system [17][18]. Management Commentary - The CEO of NexGen expressed satisfaction with the 2025 outcomes, highlighting the systematic outline of mineralization and the growth potential of the PCE discovery [17]. - The Vice President of Exploration noted that the successful 2025 program positions NexGen to enter 2026 with a deeper understanding of the high-grade system and numerous targets remaining to be tested [18].
