NexGen Energy (TSX: NXE) this morning is reporting that they have encountered the highest grade drill results to date at the Patterson Corridor East deposit. Those results come from hole RK-25-256, which intersected mineralization down-dip of prior drilling.
Highlights from the results include:
- RK-25-256: 21.4% U3O8 over 5.5 metres from a depth of 590.0 metres
- Including 46.1% U3O8 over 2.5 metres
- Including 74.8% U3O8 over 0.5 metres
- And 5.28% U3O8 over 1.5 metres from a depth of 596.0 metres
Hole RK-25-256 is said to be found 119 metres down-dip of hole RK-25-232, which previously intersected 15.9% U3O8 over 15.0 metres, and 51 metres down-dip of hole RK-25-254, which drilled 11.3% U3O8 over 10.5 metres.

Following these latest results, high grade mineralization has been identified over 215 metres from hole RK-25-254 through hole RK-24-222. The deposit as a whole was previously said to have been defined along 600 metres of strike and 600 metres of vertical extent.

“RK-25-256 high-grade assay results, consisting of ultra-high grade 0.5 m 74.8% U3O8 takes PCE into a rare mineralized category on a world scale for uranium deposits. This type of basement-hosted mineralization is synonymous with Arrow, only 3.5 km to the west. It is clear, the frequency of this ultra-high grade category of intercepts at Arrow and now PCE, is evidence of a very significant mineralizing event occurring at Rook I and in the surrounding region of the southwest Athabasca Basin in Saskatchewan,” commented NexGen CEO Leigh Curyer on the results.
