King River Resources Limited has advanced exploration activities at its Mindoolah Gold Project in Western Australia’s Murchison Province by commissioning an expanded high-resolution aeromagnetic survey and scheduling a systematic soil sampling program.

The work follows King River Resources entering into an acquisition agreement for the project in February 2026 before exercising an option to acquire 100% ownership in March. Historical records indicate past production of approximately 5,726 ounces at an average grade of 19.02 g/t gold from the historically mined area.

A systematic soil sampling program comprising approximately 418 samples is scheduled to begin on 30 August 2026 across priority target areas. Samples will be processed using Ultrafine+™ analysis to define geochemical responses associated with recently identified structural targets.

In addition to surface sampling, the company has commissioned an expanded airborne magnetic survey covering approximately 260 square kilometres across the broader area, spanning 5,939 total line-kilometres. Field mobilisation is expected in approximately three weeks.

Jarahfire Drilling has been secured as the preferred reverse circulation drill contractor, with site mobilisation targeted for early October 2026.

“Mindoolah is entering a very exciting and active phase of exploration, driven by the rollout of our Ultrafine+™ soil sampling program and a major 260 km² high-resolution aeromagnetic survey.”

“Importantly, securing our preferred RC drill contractor ensures a seamless transition into drill testing once this targeting phase is complete. By integrating these new surface datasets alongside our pending Phase 1 assay results, we will refine and rank our highest-conviction structural targets ahead of our Phase 2 RC drilling campaign in October.”

— Graham Gadsby, Managing Director

The upcoming programs combine geochemical and geophysical datasets with existing geological models and pending Phase 1 drill assay results to refine structural targets ahead of the October drilling campaign.
