NexGen Boosts Patterson Corridor East High-Grade Zone by 33 Percent
NexGen Energy has expanded the vertical reach of its high-grade uranium zone at Patterson Corridor East by a third, underpinning the ongoing growth of its flagship Rook I Project as construction nears.
- High-grade subdomain vertical extent increased to 550m
- Multiple drill holes confirm strong continuity of mineralization
- Winter program completed 12,758m of drilling with summer drilling imminent
- Parallel trend shows potential for additional mineralization
- Rook I Project construction set to start summer 2026
Significant Vertical Growth at Patterson Corridor East
NexGen Energy (ASX:NXG) has reported a 33% increase in the vertical extent of the high-grade uranium subdomain at its Patterson Corridor East (PCE) deposit, now stretching 550 metres with a strike length of 210 metres. This expansion was driven by drill hole RK-26-280c1, which intercepted a cumulative 4.2 metres of mineralization above 10,000 counts per second (cps), including a 0.6-metre section exceeding 61,000 cps at 834 metres below surface.
The results underscore the robust internal continuity of high-grade mineralization at PCE, with holes RK-26-271c1, RK-26-276, and RK-26-285 delivering substantial intercepts between 600 and 700 metres depth. Notably, RK-26-271c1 recorded 12.6 metres above 10,000 cps, including 2.3 metres of off-scale readings, reinforcing the down-plunge continuity of the mineralized shoot.
Expanding the Mineralized Footprint and Parallel Trends
Alongside the main PCE zone, NexGen’s drilling 600 metres to the southeast targeted a parallel geological trend showing prospective structures and alteration features. These early indications suggest potential repetitions of mineralization within the broader PCE system, offering further upside for resource growth.
Since the initial discovery in March 2024, NexGen has completed 115 drill holes totalling over 72,000 metres at PCE, with 79 holes intersecting mineralization and 54 confirming high-grade uranium above 10,000 cps. The winter program alone contributed 12,758 metres of drilling, focusing on expanding the high-grade footprint ahead of a planned 29,200-metre summer campaign commencing in late May.
Positioning for Construction and Future Growth
Leigh Curyer, NexGen’s CEO, highlighted the rapid pace of growth at PCE and the need for continued drilling to fully delineate the zone’s extent. With construction of the Rook I Project scheduled to begin this summer, the company is simultaneously advancing exploration to identify additional mineralized zones that could enhance the project’s long-term profile.
The Rook I Project, poised to become the world’s largest low-cost uranium mine, recently secured its final federal approval to proceed, as detailed in NexGen’s earlier update on the final federal approval. This milestone sets the stage for a four-year construction timeline, aiming to meet growing global demand for Canadian uranium with high environmental and social governance standards.
While gamma spectrometer readings provide promising preliminary indications, NexGen cautions that true thicknesses of mineralized zones remain to be confirmed through resource modelling and assay results. The company’s forward-looking statements acknowledge inherent uncertainties, including market conditions and operational risks, but the current drilling success reinforces NexGen’s strategic position in uranium exploration and development.
Bottom Line?
NexGen’s winter drilling success at Patterson Corridor East cements its growth trajectory, but upcoming summer results and resource updates will be critical to gauge the full scale of this uranium asset.
Questions in the middle?
- How will summer drilling refine the size and grade continuity of the Patterson Corridor East zone?
- What impact might expanded mineralization at PCE have on the Rook I Project’s feasibility and production profile?
- Could the parallel trend southeast of PCE unlock new high-grade zones to extend NexGen’s resource base?
