Diablo Identifies Silver–Antimony Drill Targets in Utah as Copper Mineralization Confirmed at Phoenix Project

Why It Matters

The discoveries position Diablo to develop a diversified silver‑antimony‑copper resource in a Tier‑1 US copper district, enhancing its growth prospects and contributing to domestic critical‑metal supply chains.

Key Takeaways

• DDIP survey targets STAR‑01 anomaly for precise drilling
• Rock samples show >3,000 g/t silver, 1.37 g/t gold
• Phoenix intercepts up to 12.2 m @ 0.35% copper
• Flying Diamond Fault extends >1,000 m strike
• Further drilling slated to define mineralisation geometry

Pulse Analysis

Utah’s mineral‑rich terrain is gaining attention as the United States seeks domestic sources of copper and other critical metals. Diablo Resources’ recent focus on the Star Range and Phoenix projects underscores a strategic shift toward multi‑metal deposits that can deliver both precious and base metals. By leveraging a Dipole‑Dipole Induced Polarisation (DDIP) survey, the company aims to refine target selection, reducing exploration risk while capitalising on the region’s historic skarn and carbonate‑replacement systems.

The technical data emerging from the field are compelling. Surface sampling at the North Star prospect revealed silver concentrations exceeding 3,000 g/t alongside notable gold and antimony values, indicating a robust epithermal system. Concurrently, the Phoenix Copper Project’s eight reverse‑circulation holes intersected copper‑silver mineralisation over a 300‑metre strike length, with the most significant intercept measuring 12.2 m at 0.35% Cu and 13 g/t Ag. These results validate Diablo’s geological model that the Flying Diamond Fault, a structurally controlled conduit for mineralising fluids, continues eastward, offering over a kilometre of prospective strike for future drilling.

From an investment perspective, the convergence of high‑grade silver‑antimony targets and expanding copper mineralisation enhances Diablo’s asset portfolio and aligns with broader market trends favouring diversified, low‑carbon resource projects. The planned expansion of drilling campaigns will not only delineate resource boundaries but also provide the data needed for potential JORC‑compliant resource estimates. As demand for copper in renewable‑energy infrastructure accelerates, projects like Phoenix could become pivotal contributors to the domestic supply chain, positioning Diablo as a notable player in the evolving US mining landscape.
