Greenvale Energy Advances 9km Uranium Paleochannel Target at Thunderball Project

Expanded Uranium Target at Thunderball Project

Greenvale Energy Limited (ASX:GRV) has bolstered its exploration narrative with updated geochemical data from its Powers Prospect within the Thunderball Uranium Project in the Northern Territory. The company has extended the known strike length of this paleochannel uranium target to approximately 9 kilometres, with widths up to 400 metres, significantly enhancing the scale and exploration potential of the area.

Ground-based surveys using RS-125 scintillometers and portable XRF devices have returned uranium readings consistently 3-4 times above natural background levels, reinforcing the airborne radiometric anomalies initially identified. These qualitative spot measurements, while not definitive assays, provide a compelling indication of uranium mineralisation, particularly calcrete-hosted deposits at the top of a paleochannel system.

Geological Insights and Exploration Techniques

The geological setting at Powers Prospect features Tindal Limestone formations overlain by calcrete and other evaporitic sediments, creating a favourable environment for uranium accumulation. The discovery of structural features aligned with the regional Hayes Creek Fault system suggests multiple pathways for uranium-bearing fluids, enhancing the prospectivity of the area.

Greenvale's systematic approach combines remote sensing, airborne radiometrics, and detailed ground mapping to refine targets ahead of drilling. The company plans to undertake a close-spaced Airborne Electromagnetic (AEM) survey to map the base of paleochannel systems more precisely, a method proven effective in similar uranium provinces.

Permitting and Next Steps

Permitting processes are underway for exploratory aircore drilling at Powers Prospect, with applications for an Environmental Mining Licence in progress. This marks a critical step toward testing the target's depth and grade potential. Concurrently, Greenvale is reviewing historical exploration data across its project areas and advancing its strategic acquisition of the Pine Creek Uranium Project to consolidate a district-scale landholding.

Managing Director Alex Cheeseman highlighted the rapid progress, noting the prospect's identification less than six months after EL34157 was granted. The company’s integrated exploration strategy is positioning it to make a meaningful uranium discovery in a region with relatively limited modern exploration.

Cautionary Notes on Assay Data

While the RS-125 and portable XRF readings provide encouraging signals, Greenvale emphasises these are qualitative spot measurements subject to variability and not substitutes for laboratory assays. Definitive results from independent laboratory chemical analyses are pending, which will be critical for confirming uranium grades and informing resource estimation.
