NexGen Energy Makes New High Grade Discovery At Rook I Project
NexGen Energy (TSX: NXE) has made a new discovery at its Rook I property in the Athabasca Basin of Saskatchewan. The discovery follows drill testing, which has led to its best hole to date drilled within the discovery-phase of exploration across its portfolio.
Highlights from the results include:
- RK-25-232: 3.9 metres of >61,000 cps, from a depth of 457.5 metres
The major intercept is said to have been included within a 13.8 metre interval of rich uranium concentration that began at a depth of 452.2 metres. Four other holes meanwhile intercepted grades containing in excess of 61,000 cps, with those holes all at least 50 metres from the discovery hole.
The new zone, which marks one of the shallowest high-grade intersections at the Patterson Corridor East area to date, currently has a strike length of 210 metres, and is known to contain a vertical extent of 335 metres.

“This intercept from RK-25-232 is geologically exceptional and represents a transformational moment taking PCE into a category to rival Arrow at the same stage of drilling. Discovering mineralization of this intensity so early in our 2025 program outpaces the success pattern experienced at the Arrow Deposit. [..] To put this into context, the width of high-grade intense mineralization in RK-25-232 at PCE was first encountered at Arrow well into the delineation phase of resource definition,” commented Leigh Curyer, CEO of NexGen Energy.
Ongoing drilling is now set to focus on growing and defining the new high grade zone.
NexGen Energy last traded at $7.06 on the TSX.
