Greenvale’s uranium footprint at Oasis grows with fresh gamma results

Epiroc was re-engaged to complete the downhole program, with the new spectral gamma data continuing to map high-grade zones that line up with structures defined in the close-spaced magnetics.

Standout results include 1m at 1,277ppm and 1m at 1,608ppm eU₃O₈ in hole 25GRV008, 1m at 1,386ppm in 25GRV009 and 1.5m at 1,426ppm from 25GRV010.

Importantly, holes 25GRV011 and 25GRV012 point to a second north–south oriented structure west of the main Oasis shear, suggesting a parallel high-grade position that has not been previously modelled.

Greenvale CEO Alex Cheeseman said these exciting downhole spectral gamma logging results, combined with initial assay results from our recent drilling, reinforce the quality of Oasis as a high-grade uranium project with scale potential.

“This includes clear opportunities to extend high-grade mineralisation both along strike and down-plunge and to make significant new discoveries within the broader tenement,” he said. 

“The results also demonstrate the emergence of consistent patterns within our different geoscientific datasets – from the Sentinel-2 gas anomalies that coincide with structural features seen in the ground magnetics, and their respective correlation with our high-grade drilling results. 

“These patterns allow us to build a comprehensive, system-style approach to our exploration strategy that we will then apply to regional targets surrounding the Oasis deposit,” Cheeseman added. 

“The design of our pending trenching program has also been determined by these patterns, with each trench strategically positioned over a zone of structural and mineralogical interest.”

Covering about 90km2 in north QLD, 300km west of Townsville, the Oasis project sits entirely within the Lynd Station pastoral lease. 

Greenvale kicked off its maiden drill program between July and September to validate historical results, test for extensions down-plunge and along strike and tighten the geological model of the deposit. 

That work is intended not only to refine Oasis itself, but to inform the approach to other targets across the broader EPM 27565 tenement.

All diamond core from the remaining six holes have now been processed, with samples submitted to the laboratory for chemical assay and results expected during Q4 CY2025.
