Diablo Resources Limited has completed earthworks at the North Star Prospect within its Star Range Project in Utah, establishing vehicular access and drill pads for an upcoming maiden diamond drilling program.

The initial campaign will comprise five holes for approximately 1,000 metres of drilling, designed to test subsurface mineralised breccia-vein systems beneath high-grade surface sampling results that include up to 3,043 g/t silver and 1.37 g/t gold. Geological mapping and soil sampling continue across broader structural trends to refine target ranking for subsequent phases.

The Star Range operations run in parallel with ongoing work at the Horn Silver Project, located approximately 15 kilometres away in Utah's Frisco mining district. Diablo Resources holds an exclusive option over 101 patented claims and an 80% interest in 101 unpatented lode claims at Horn Silver, with the option exercise scheduled for completion in September 2026. Reconnaissance mapping and regional sampling have commenced across the unpatented claims while historical datasets are integrated to finalise a maiden drill program targeting extensions to the historic Horn Silver Mine.

“The completion of earthworks at Star Range and the progress made at Horn Silver mark important steps in advancing our district-scale critical minerals strategy in Utah. We now have drill-ready access at Star Range and a clear pathway to define our maiden drill program at Horn Silver as initial reconnaissance and data integration continue. With both projects moving forward in parallel, the Company is well positioned to begin testing high-priority targets across two highly prospective mineralised system in coming months.” 

— Lyle Thorne, CEO

Field teams are also advancing reconnaissance across other Star Range targets, including South Star, East Star, and gold anomalies within the Utah Trust Lands Administration lease, as the company prepares to mobilise rigs for the North Star drilling phase.
