GreenTech Metals Limited has commenced a heritage survey at the Munni Munni PGE-Cu-Ni Project in Western Australia’s West Pilbara region, working alongside the Ngarluma Traditional Owners to clear proposed new drill locations and access tracks across the mineralised footprint and high-priority basal zone target areas.

The survey is designed to pave the way for systematic step-out drilling targeting basal copper and platinum group element targets highlighted in recent technical reviews.

“Commencing this heritage survey is a key step in unlocking the broader potential of the Munni Munni system. By commencing drilling at Whundo and retaining the option to drill from existing pads at Munni Munni, we expect to maximise drill rig utilisation ahead of heritage survey completion.”

— James Rattenbury, Chief Executive Officer

Drilling is currently underway at the Whundo project in parallel, maintaining continuous activity and keeping rig utilisation high while the Munni Munni survey is completed.

The current field work runs alongside an 8,300-metre drill programme across the Munni Munni and Whundo projects. Subsequent catalysts include the completion of the 8-day heritage survey which commenced on 10 August 2026, the receipt of upcoming assay results, the planned mobilisation of a second drill rig following further heritage clearances, and the eventual delivery of an updated Mineral Resource Estimate and Scoping Study for Munni Munni.
