NexGen Announces New Off-Scale Mineralization Intersected at Patterson Corridor East (PCE) and Continued Expansion of High-Grade Sub Domain

Executive Summary

• NexGen’s summer 2025 drill program at the PCE project intersected multiple high‑grade uranium shoots, including two off‑scale (>61,000 cps) intervals (RK‑25‑254 and RK‑25‑256) located 51 m up‑dip and 119 m down‑dip from the benchmark hole RK‑25‑232.
• New step‑out holes (RK‑25‑246, RK‑25‑247, RK‑25‑251, RK‑25‑254, RK‑25‑256) delivered broad mineralized intercepts (>500 cps), with several >10,000 cps and two >61,000 cps sections, confirming the repeatable high‑grade shoots spaced ~70 m apart.
• To date, 21,969 m of the planned 43,000 m program have been drilled in 2025; overall 79 holes (53,089 m) since discovery, with 48 mineralized—including 34 >10,000 cps and 14 off‑scale (>61,000 cps).

Key Details

• RK‑25‑254 & RK‑25‑256:
• Intersected 2.0 m (RK‑25‑254) and 2.1 m (RK‑25‑256) of off‑scale (>61,000 cps) uranium at depths ~454 m, the shallowest massive‑uranium hits recorded by NexGen.
• New Broad Intercepts (>500 cps):
• RK‑25‑246 – 20.5 m total, including 2.5 m >10,000 cps.
• RK‑25‑247 – 18.0 m total, including 2.5 m >10,000 cps.
• RK‑25‑251 – 9.5 m total (>500 cps).
• RK‑25‑254 – 19.5 m total, including 5.0 m >10,000 cps and 2.0 m >61,000 cps.
• RK‑25‑256 – 10.0 m total, including 3.3 m >10,000 cps and 2.1 m >61,000 cps.
• High‑Grade Shoot Continuity:
• The high‑grade zone now extends a minimum of 200 m from RK‑25‑254 to RK‑24‑222, indicating an emerging pattern of shoots spaced ~70 m apart (Figures 2‑3).
• Program Progress:
• 21,969 m drilled in 2025 (≈51% of the year’s target).
• Cumulative drilling since discovery: 79 holes, 53,089 m.
• Mineralized holes: 48/79; high‑grade (>10,000 cps): 34; off‑scale (>61,000 cps): 14.
• Geological Context:
• Intercepts occur in competent basement rock consistent with the Arrow deposit model—shallow depth (454 m) and open 300 m up‑dip, fully contained laterally.
• Management Comments:
• CEO Leigh Curyer highlighted the results as evidence of a “generational uranium discovery” with world‑class potential.
• VP Exploration Jason Craven noted the shallow, intense high‑grade hits rival those at Arrow (3.5 km away).

Notable Quotes

• Leigh Curyer, CEO: “PCE is evolving in real time into a world‑class system…continuity of high‑grade mineralization and growth potential.”
• Jason Craven, VP Exploration: “Early summer drilling results are building on emerging interpretations that include systematic repetition of high‑grade shoots within the overall mineralized footprint.”
