Diablo Resources Ltd has commenced a maiden diamond drilling program at the North Star Prospect, providing the first subsurface test of priority targets at its 100% owned Star Range Project in Utah.

The initial campaign comprises approximately 1,000 metres across five diamond holes designed to test induced polarisation geophysical anomalies and evaluate the scale, continuity, and geometry of the polymetallic mineralised system at depth. Existing regulatory approvals provide flexibility for up to 27 holes from 12 pads to allow follow-up testing as ongoing technical interpretation warrants.

Surface work across the prospect has previously returned high-grade rock-chip results reaching up to 3,043 grams per tonne silver and 1.37 grams per tonne gold, alongside antimony and copper values. The company acquired full ownership of Star Range following a $2.0 million capital raise completed in September 2025.

“Our U.S. exploration team is excited to have drilling underway at North Star. Star Range continues to demonstrate strong potential across multiple target zones, and this program will provide important subsurface data to guide the next phase of exploration.”

— Lyle Thorne, CEO

Diablo will complete the initial five-hole program and subsequently release assay results from the diamond drilling to refine its geological model and guide ongoing target generation across the wider project area.
