Greenvale’s 42 km Magnetic Survey Reveals Complex Faults Driving Uranium Mineralisation

Exploration Momentum Builds at Oasis

Greenvale Energy Limited (ASX, GRV) is accelerating its exploration efforts at the Oasis Uranium Project in Queensland, following a successful maiden drilling campaign that uncovered multiple high-grade uranium intercepts. The company has now completed a close-spaced ground magnetics survey spanning 42 line-kilometres, alongside the acquisition of Sentinel-2 multi-spectral satellite data, both of which have unveiled new structural features and geochemical anomalies that could signal further uranium mineralisation beyond previously known zones.

Decoding Structural Complexity

The high-resolution magnetic survey has revealed a network of cross-cutting faults oriented northwest-southeast and northeast-southwest, adding layers of structural complexity to the Oasis shear zone. These newly identified fault systems appear to control the distribution of uranium mineralisation, a critical insight that refines Greenvale’s geological model. Complementing this, the Sentinel-2 data has detected anomalies in helium, hydrogen, and radon gases, known pathfinders for uranium deposits, that correlate closely with the magnetic structures and high-grade drill results.

Strategic Trenching to Guide Next Drilling Phase

Building on these findings, Greenvale is preparing to commence a trenching and sampling program designed to test the strike and lateral extent of the Oasis shear. Nine trenches, each approximately 150 metres long and 1-2 metres wide and deep, will be excavated to collect geological and structural data. This cost-effective approach aims to sharpen the focus for upcoming drilling campaigns, potentially unlocking new uranium zones within the project area.

Implications for Regional Exploration

Beyond the immediate Oasis deposit, the correlation between geological structures, geophysical data, and gas anomalies offers a promising framework for regional target generation across Greenvale’s exploration permit. The company is actively developing these regional targets, which could expand the project’s resource base and enhance its strategic positioning in the uranium sector.

Looking Ahead

While final assay results from the recent drilling are pending, the integration of multi-disciplinary datasets underscores Greenvale’s methodical approach to exploration. By focusing on structural controls and leveraging cutting-edge geophysical and satellite technologies, the company is well-positioned to advance its understanding of the Oasis mineral system and pursue new discoveries in a market increasingly attentive to uranium’s role in a low-carbon future.
