Latest Development: High-Grade Subdomain Expansion at PCE

In an announcement dated 24 August 2026, NexGen reported results from the early portion of its 2026 summer drilling at Patterson Corridor East (PCE). The company stated that the high-grade subdomain was expanded both up dip and down dip.

Hole RK-26-293 intersected a cumulative 4.7 m of greater than 10,000 counts per second (cps), including 0.1 m of greater than 61,000 cps at 930 m depth. The company said this lifted the vertical extent of the high-grade subdomain by 94 m, a 17% increase, to 644 m. The strike extent remained at 210 m, as recent tests focused mainly on confirming deep-seated interpretations.

Latest Development: Best 2026 Holes and Continuity Results

The company reported that down-plunge test hole RK-26-290c1 intersected multiple stacked uranium veins across 40 m of the high-grade subdomain. The cumulative result was 19.5 m of greater than 10,000 cps, including 12.9 m of greater than 10,000 cps surrounding 5.2 m of greater than 61,000 cps. NexGen said it ranks as the best hole at PCE since discovery on a cumulative greater than 61,000 cps basis.

Hole RK-26-294 intersected a cumulative 6.9 m of greater than 10,000 cps, including 3.1 m of greater than 61,000 cps, located 27 m from RK-24-222, which previously returned 17.0 m at 3.85% U3O8. The company ranked it third best at PCE on the same basis.

  • RK-26-296 returned a cumulative 3.5 m of greater than 10,000 cps, including 0.4 m of greater than 61,000 cps.
  • The company said this hole expanded the shallowest portion of PCE by 50 m along strike.
  • NexGen stated that the bulk of high-grade subdomain mineralization at PCE is 70 m shallower than the A2 High-Grade Zone.

Latest Development: Fifth Drill Rig and Program Progress

Following the results, NexGen said it is adding a fifth drill rig for the remainder of the 2026 program. Drilling at PCE recommenced on 28 May 2026, and 20,138.7 m has been completed so far in 2026 out of a planned 42,000 m, focused on high-grade growth and expansion of mineralization. Eleven holes drilled this summer, totalling 7,425.2 m, have tested PCE.

Jason Craven, Vice President of Exploration, said mineralization remains open in most directions. Leigh Curyer, Chief Executive Officer, said the team is delivering on multiple fronts alongside construction of the Rook I Project. Samples from 2026 drilling are being sent to the independent Saskatchewan Research Council Geoanalytical Laboratory, with further results to follow.

Risks and Catalysts on Watch

The announcement points to the following items:

  • Additional tests of the parallel trend at PCE are planned for the remainder of summer drilling.
  • Results from samples submitted to the Saskatchewan Research Council laboratory are still to follow.
  • The 2026 program has completed 20,138.7 m of a planned 42,000 m.
  • The release states that results are from a handheld spectrometer, and that true thicknesses are yet to be determined.
  • The release notes that resource modelling with an updated mineral resource estimate is required before true thicknesses can be determined.
  • The company cautions that forward-looking statements are subject to risks, including the receipt of approvals and First Nations matters.

Final Word

NexGen's 24 August 2026 update described deeper and shallower extensions to the PCE high-grade subdomain, two of the best holes of the year, and the addition of a fifth drill rig. The company said further drilling and laboratory results are to come.
