NexGen has reported a 23% increase in the vertical extent of its primary high-grade subdomain at Patterson Corridor East, growing from 335 meters to 412 meters, with a 210-meter strike length confirmed by the concluding holes of its 2025 program. The overall mineralized footprint has expanded to 700 meters vertically (up from 600 meters) and 620 meters along strike (up from 600 meters), remaining open in multiple directions. Notably, hole RK-25-271 intercepted 5.8 meters of cumulative high-grade scintillometer readings exceeding 10,000 counts per second (cps) and 0.8 meters of off-scale readings over 61,000 cps in competent basement rock, located 65 meters down-dip of a previous 21.4% U₃O₈ intersection from hole RK-25-256. Since discovery, NexGen has completed 102 drill holes totalling 69,042.2 meters at Patterson Corridor East, with 67 holes intersecting mineralization, including 45 that surpassed 10,000 cps and 17 that were off-scale.

NexGen will undertake its largest drilling campaign to date at Patterson Corridor East in 2026, targeting 42,000 meters of diamond drilling focused on high-grade growth and further extension of the mineralized footprint. The program will include at least eight 200-meter-spaced step-out tests approximately 600 meters southeast of the current discovery to evaluate potential repetitions of basement-hosted mineralization. In parallel, the company will conduct its inaugural drilling at the 100%-owned SW3 property, allocating 3,500 meters to greenfield testing of high-priority targets identified by geophysical surveys. This dual-track approach builds on the rapid advancement achieved in 2025 and positions NexGen to delineate new high-grade domains while probing the broader Athabasca Basin system for additional discoveries.
