Star Range is the site of intense historical mining activity until the mid-1960s producing lead, zinc, copper, gold and silver.

Diablo Resources (ASX:DBO) has identified a silver-antimony anomaly over one kilometre long at the Star Range project in Utah, and the Australian explorer now plans to move quickly on exploration follow-ups.

Naiden soil sampling, high-grade rock samples and historical workings have highlighted the potential for multiple mineralised zones at the Utah prospect, which the company says “continues to build confidence in the potential.”

‘At South Star, the silver–antimony anomaly now extends for more than one km and remains open to the northeast,” said CEO Lyle Thorne today. “This, combined with several historic workings and high-grade rock samples, reinforces our view that the project hosts multiple mineralised zones.”

Ground geophysics has been completed; further plans include extensional soil sampling to the northeast. The use of ground- based IP will also be investigated.

“We look forward to receiving the results to further refine our drill targets across the identified high-grade silver-antimony-gold surface anomalies. Geochemical sampling is also underway across several additional targets, with assays pending,” Mr Thorne told Diablo shareholders on Monday morning.

“The coming months promise to be both busy and exciting as we advance toward our maiden drilling program at North Star in Q2 2026.”

The U.S. project lies within the Star Range in southwestern Utah, a site of intense historical mining activity until the mid-1960s, producing lead, zinc, copper, gold, and silver. The area hosts numerous old workings, the majority of which were exploited in the late 1800s for base and precious metals.

Recent mapping located several old workings with silver to 231 grams per tonne (g/t) and 0.1% antimony. Historical soil results from South Star increase the overall length of the prospective trend to more than 2,500m.

DBO has been down -4%, to 2.4c. Mkt cap $5.896M.
