Diablo Resources confirms antimony upside within high-grade critical minerals footprint at Horn

• Multiple high-grade silver targets continue to emerge across project
• Grab sampling from historical dumps identifies antimony associated with silver
• Project hosts Horn silver mine, one of Utah’s former premier silver producers
• Results highlight potential for polymetallic mineralisation across multiple targets

Diablo Resources (ASX: DBO) has confirmed high-value antimony potential in ongoing regional exploration within the Horn project in Utah, USA.

A program of 65 reconnaissance rock samples has returned silver assays of up to 1,580 grams per tonne (g/t )at the Gossan prospect, while sampling at the historic Horn silver mine has identified antimony associated with silver-bearing material.

CEO, Lyle Thorne, just back from a visit to the site, said additional silver and gold results from the Drum prospect further support the company’s ongoing evaluation of multiple mineralised structures across Horn.

“The latest regional sampling results continue to expand our understanding of the polymetallic footprint of the Horn project, identifying additional silver mineralised zones across areas that have seen little to no historical drilling,” he said.

“These results reinforce the exceptional exploration potential of the district and provide multiple opportunities for follow-up evaluation.”

Mr Thorne told shareholders the company has now established a growing pipeline of high-priority drill targets across several prospective mineralised structures.

Target ranking is underway to ensure proposed drilling is directed towards the most compelling opportunities, with planning and logistics progressing ahead of an anticipated Q1 2027 drilling program.

“Having spent the past two weeks on site, I am incredibly excited by the opportunity before us. The historic Horn silver mine was once one of Utah’s significant silver producers, and our focus is now on systematically exploring the project to better understand its potential.

“It would be immensely rewarding to see the historic Horn silver mine returned to its former glory in the highly supportive mining jurisdiction of Utah, USA.”

Diablo will now integrate recent sampling results into regional target rankings and complete follow-up mapping and sampling on priority silver-antimony targets.

This work will help advance drill target generation across the project as the company finalises permitting in the lead-up to commencing the maiden drilling program.

DBO was steady at 0.8¢ with a Mkt cap of $4.328M prior to markets opening.
