Greenvale Energy Uncovers High-Grade Uranium Extensions at Oasis Project
Greenvale Energy’s recent spectral gamma logging at the Oasis Uranium Project reveals significant high-grade uranium extensions, reinforcing the deposit’s scale potential and prompting a new trenching program.
- Five of six recent drill holes show high-grade uranium intercepts exceeding 1,000ppm eU3O8
- Spectral gamma results align with structural data from ground magnetics surveys
- Potential discovery of a second north-south high-grade shear zone adjacent to main deposit
- Diamond core assays pending, expected in Q4 2025
- Trenching program underway to test new structural targets informed by integrated geoscientific data
Spectral Gamma Logging Confirms High-Grade Extensions
Greenvale Energy Limited (ASX, GRV) has announced compelling results from downhole spectral gamma logging at its Oasis Uranium Project in Queensland. The logging of six recently completed drill holes has identified multiple high-grade uranium intercepts, with five holes returning grades exceeding 1,000 parts per million equivalent uranium oxide (ppm eU3O8). Notably, intercepts such as 1m at 1,608ppm eU3O8 and 1.5m at 1,426ppm eU3O8 underscore the deposit’s robust mineralisation potential.
The spectral gamma data correlates strongly with structural features delineated by recent close-spaced ground magnetics surveys, reinforcing the geological model and suggesting extensions of mineralisation both along strike and at depth. This integrated approach enhances confidence in the continuity and scale of the deposit.
Emergence of a Second High-Grade Structure
Intriguingly, drillholes 25GRV011 and 25GRV012 indicate the presence of a second, parallel north-south oriented shear zone west of the main Oasis Shear. If confirmed, this could represent a significant new mineralised structure, potentially expanding the resource footprint. The company plans to test this hypothesis through a strategically designed trenching program, which commenced in late October 2025.
Greenvale’s CEO, Alex Cheeseman, highlighted the importance of these findings, noting the consistent patterns emerging across multiple datasets; from spectral gamma logs and ground magnetics to Sentinel-2 gas anomaly mapping. This system-style exploration strategy aims to unlock further discoveries within the broader tenement area.
Next Steps, Assays and Trenching
While spectral gamma logging provides rapid and reliable uranium estimates, final confirmation awaits chemical assay results from diamond drill core samples. These assays, submitted to Intertek, are expected in the fourth quarter of 2025 and will be critical to validating the spectral data and refining the geological model.
The ongoing trenching program, informed by the integrated geoscientific insights, is designed to target zones of structural and mineralogical interest. This work will further delineate mineralisation controls and potentially identify new high-grade zones, setting the stage for subsequent drilling campaigns.
Strategic Implications for Greenvale Energy
The Oasis Uranium Project, covering 90 square kilometres in North Queensland, represents a cornerstone asset for Greenvale Energy’s portfolio. The recent drilling and spectral gamma results not only validate historical exploration but also demonstrate the project’s growth potential. The company’s methodical approach; leveraging advanced geophysical techniques and multi-disciplinary data integration; positions it well to advance Oasis toward resource definition and eventual development.
As the uranium market remains sensitive to supply-demand dynamics amid the global energy transition, Greenvale’s progress at Oasis could attract increased investor attention. The pending assay results and trenching outcomes will be key milestones to watch in the coming months.
Bottom Line?
Greenvale’s Oasis project is shaping up as a high-grade uranium contender, with upcoming assays and trenching poised to unlock further value.
Questions in the middle?
- Will the pending chemical assays confirm the high-grade spectral gamma results?
- How extensive is the newly identified second shear zone, and what impact could it have on resource estimates?
- What are the implications of these findings for Greenvale’s broader regional exploration strategy?
