ASX 200 uranium stock slips despite strong drill intercepts
NexGen shares are slipping despite the company reporting on a promising final batch of assay results from its 2025 drill campaign.
The ASX 200 uranium stock said the results from its Patterson Corridor East (PCE) discovery near the proven Arrow Deposit and within NexGen's broader Rook I project in Canada highlight the "expansion and continuity of the high-grade subdomain" at PCE.
Among the top results, one drill hole returned 13.0 metres at 5.2% uranium concentrate (U3O8), including 0.5 metres at 30.2% uranium concentrate at 400 metres below surface.
NexGen also highlighted a second drill hole, which returned 10.0 metres at 3.95% uranium concentrate, including 0.5 metres at 33.3% uranium concentrate at 670 metres below surface.
The company said the strong results indicate the potential extension of mineralisation at depth, where the system is open. The miner added that the assays have also now confirmed a new secondary high-grade subdomain at the project.
What did NexGen management say?
Commenting on the drill results that have yet to lift the ASX 200 uranium stock today, NexGen founder and CEO Leigh Curyer said, "These assay results from 2025 drilling confirm high-grade mineralisation and the expanding scale of PCE."
Curyer added:
The combination of high-grades, continuity, scale and geotechnical characteristics continue to highlight the similarities between PCE and the mighty Arrow Deposit. The opening up of a new high-grade subdomain emphasises significant growth potential remains at PCE.
As for the broader uranium market, Curyer noted:
With the structural supply deficit in the market widening, and the impacts of the industry wide underinvestment in the uranium supply chain for a generation, the urgency of finding and bringing online new, reliable uranium supply has never been greater.
Looking to what's ahead for NexGen, Curyer concluded:
As the Rook I Project enters into major construction this summer, we continue to advance PCE to ensure that NexGen optimises its unparalleled opportunity to become one of the world's most important mining company in delivering energy fuel for the current and future generations.
