Greenvale Energy (ASX: GRV) has defined new extensional opportunities at the Oasis uranium project in North Queensland after completing its latest trenching program.
The program uncovered geological, structural, and radiometric patterns that appear to support the presence of a second mineralised structure.
Chief executive officer Alex Cheeseman said the results would play a central role in shaping the company’s expanded geological model for 2026.
Six Trenches Completed
Greenvale Energy completed six trenches totalling about 775 metres at Oasis between 28 October and 10 November, with each trench measuring 1.2m wide and up to 2.5m deep .
Preliminary scintillometer readings were consistently low in the western area but increased sharply towards the main shear zone, with some zones returning surface responses of more than 2,000 counts per second.
The elevated readings prompted the field team to refine trench placement during the program, allowing it to focus on areas of greatest prospectivity.
This process led to the identification of a second structure that correlates with zones mapped during earlier magnetic and geological work, prompting the addition of one trench and reassignment of another.
Both of these returned internal radiometric responses exceeding 700 counts per second, correlating with megacrystic granite and biotite-chlorite schists that also host mineralisation at the main Oasis structure.
Rehabilitation and Field Completion
All six trenches and all twelve drill sites have now been backfilled, scarified and rehabilitated, with field personnel and equipment fully demobilised from the project area following completion of rehabilitation works, including restoration of older trenches first excavated in the 1970s .
Samples from the 449 trench intervals have been submitted to Intertek for geochemical analysis, with assay results expected over the next one to two months.
The company will also receive the final assays from six remaining drill holes from its recent program in early December, allowing all datasets to be compiled into a deposit-wide model.
Mr Cheeseman said the emerging patterns across geological, geophysical, geochemical, and structural datasets “create an excellent exploration blueprint for us to target exciting regional opportunities surrounding Oasis,” which will be the company’s priority entering the New Year.
