NexGen expands Sask uranium drilling: key takeaways for mine planners and engineers

30 Second Briefing
NexGen Energy is expanding drilling at the Patterson Corridor East discovery in Saskatchewan’s Athabasca Basin, adding a fifth rig after gamma probe results showed continuous high-grade uranium, including hole RK-26-293 with 4.7 metres above 10,000 cps and a 0.1-metre interval over 61,000 cps. Additional holes RK-26-290c1 and RK-26-294 returned 19.5 metres and 6.9 metres respectively above 10,000 cps, with 3.1 metres in RK-26-294 exceeding 61,000 cps, and mineralisation remains open in most directions. The company has drilled 20,138.7 metres of a planned 42,000 metres while concurrently building the nearby Rook I project at the Arrow deposit, 3.5 km west.
Technical Brief
- Continuous core samples are dispatched to the Saskatchewan Research Council Geoanalytical Laboratory for independent uranium assay.
- PCE lies in the Athabasca Basin, over 600 km southeast of Saskatoon, implying remote logistics.
- Mineralisation remaining open in most directions suggests additional drilling along strike and down-dip is likely.
- Similar Athabasca projects often transition from gamma-guided exploration to resource definition drilling once SRC assays confirm grade continuity.
Our Take
Canada’s new national uranium strategy, which highlights Athabasca Basin projects including NexGen’s, means any additional high‑grade discoveries near the Arrow deposit could quickly gain strategic importance for meeting the country’s 2035 export‑doubling ambitions.
NexGen’s repeated appearance in our uranium‑tagged coverage, alongside Cameco and Denison Mines, indicates it is now consistently grouped with established Canadian producers in policy and market discussions rather than being viewed purely as a single‑asset developer.
