Great Dirt Resources has completed a systematic soil sampling program at its Pilbara lithium project in Western Australia, collecting 805 samples across tenement E45/6863 to refine priority exploration targets.

The 67-square-kilometre tenement sits approximately 43 kilometres from Pilbara Minerals' Pilgangoora deposit and adjacent to ground held by Wildcat Resources and Sayona Mining. Wildcat Resources reported positive metallurgy testwork results from its Bolt Cutter Central lithium discovery within the surrounding district in July 2026, demonstrating an average spodumene recovery of 82.5%.

The sampling program tested newly defined geophysical and geochemical targets across the K1 to K10 target zones, covering areas associated with potassium radiometric anomalies and interpreted fertile granite margins. Historical rock chip sampling at the project has returned up to 708 ppm Li2O alongside elevated pathfinder elements including caesium, beryllium and niobium.

Completion of the 805-sample soil program is an important step in advancing Great Dirt's Pilbara exploration strategy. The program builds on the Company's recent geophysical interpretation and field mapping and provides a strong platform for incoming assay results to assist in refining and prioritising future exploration targets across the project.

All samples have been submitted to the laboratory for multi-element analysis, with assay results anticipated during the September quarter. Great Dirt will integrate the incoming data with existing geophysical datasets to refine and prioritise future exploration targets across tenement E45/6863.
