The explorer’s drilling at Oval is testing a coincident gravity anomaly and modelled prospective volcanic-hosted massive sulphide (VHMS) horizon.

Great Western’s managing director, Shane Pike, this morning told shareholders drilling at Oval is examining an interpreted core of a potentially large VHMS copper-gold mineralisation system.

Oval is located adjacent to the DeGrussa and Monty copper-gold VHMS deposits within the  Yerrida North project. The geology of the Yerrida Basin is relatively similar in lithology and age to the adjacent Bryah Basin.

Drilling at Oval will comprise a diamond drill-hole to test the extensive gravity anomaly, designed to a total depth of 750 metres. A previously reported drill-defined horizon is hosted by a siltstone unit, Great Western has flagged, with pathfinder drill assay results already returning a strong VHMS signature.

The horizon was interpreted to be at a distal position from an undersea volcanic vent that can host copper-gold enrichment, similar to the DeGrussa deposit.

“Commencement of this program marks the beginning of an aggressive exploration campaign by Great Western, where the company plans to drill test nine individual targets over the next six months,” Mr Pike said.

Following completion of drilling at Oval, Great Western will then move onto the Diorama copper-gold target, followed by drilling of six individual copper-gold targets at the nearby Juggernaut project, then drilling of the Baroo copper-gold target.

The company also plans to advance exploration on several copper-gold targets within the Yerrida Basin and, concurrent with the drilling campaigns, has the aim of progressing these targets to drill-ready status.

“Great Western is in a strong financial position, with a cash balance of $4.3 million as at end of March 2026,” Mr Pike added in his Monday update.

GTE will open at 1.7¢. Mkt cap $13.19M.
