Great Western completes Oval drilling as multi-target copper-gold campaign ramps up

An announcement from Great Western Exploration Limited ( (AU:GTE) ) is now available.

Great Western Exploration has completed a diamond drill hole at the Oval Copper-Gold Target in Western Australia’s Yerrida North Project, successfully intersecting the targeted gravity anomaly and a potential volcanic-hosted massive sulphide horizon between 650 and 750 metres depth. The hole encountered interbedded volcanic and siltstone rocks with a mafic intrusive and only trace visible chalcopyrite, which the company does not expect to yield significant copper, though assay results due in June–July 2026 will clarify any gold potential.

The company interprets the mafic intrusive as the source of the gravity high and considers the volcanic-sedimentary sequence a suitable setting for VHMS mineralisation, reinforcing its geological model at Oval despite modest visible mineralisation. Oval forms part of Great Western’s broader plan to test nine copper-gold targets between April and September 2026, with drilling to commence next at the Diorama target, then six targets at the Juggernaut Project and the Baroo target, alongside advancing additional regional copper-gold prospects to drill-ready status, underpinned by its solid cash position.
