Prospectivity analysis combining recent airborne magnetics/radiometric surveys and project-wide Sentinel-2 multispectral imagery identified 21 targets from multiple coincident geophysical anomalies, structural controls, geological setting and potentially uranium-related gas anomalies.
Greenvale Energy’s (ASX:GRV) fieldwork will involve the ground-truthing of each anomaly using ground-based scintillometer (radiometric) and portable XRF surveys, followed by geological mapping in areas of high prospectivity.
The field-based aspects of the program, which started on August 27, will run for 10-14 days with subsequent data analytics and geochemical testing expected to continue through to Q4 2025.
“This is the first on-ground field work Greenvale has undertaken on our NT projects, and so is an exciting step forward. The Henbury project is located in the Amadeus Basin, which hosts a number of world-class uranium deposits.
“The team has diligently prepared the field plan by layering and fusing multiple sources of data to identify three high-priority areas, with 21 individual points of interest highlighted for ground-based radiometrics, portable XRF surveys and geological reconnaissance.”
Henbury consists of the EL33637 and EL33638 exploration licences that host multiple anomalies defined from historical geophysical surveys which have never been properly tested.
It is prospective for sandstone-hosted uranium mineralisation, akin to proven deposits such as Core Lithium’s 8.03Mlbs U3O8 Napperby deposit.
Recent airborne magnetics/radiometrics acquired on a close 100m spacing identified three large areas of anomalism while project-wide Sentinel-2 multispectral imagery was acquired, assessed and correlated with the company’s survey data and publicly available information.
Geologically, the coincident radiometric and Sentinel-2 anomalies coincide with mapped Hermannsburg Sandstone and Ljlltera Member, which are both stratigraphically situated below the Brewer Conglomerate.
This latter formation hosts the Undandita Member sub-arkoses, sandstones, siltstones and carbonates which, in turn, hosts the Angela uranium deposit.
