How Will Diablo’s New Utah Land Boost Its Silver-Antimony Ambitions?

Strategic Expansion of Star Range Project

Diablo Resources Limited has announced a key expansion of its Star Range Silver-Antimony Project in southwestern Utah, USA, through the acquisition of an additional 646.5 acres of land. This new tenure, secured via a Utah Trust Lands Administration lease, sits directly adjacent to the high-priority South Star Prospect, effectively consolidating the company’s control over a geologically prospective area. The total project size now stands at approximately 5,242 acres, or 21.2 square kilometres, marking a significant step in scaling up the project’s potential.

Geological Continuity and High-Grade Mineralisation

The newly acquired ground aligns with known mineralised zones, extending the structural trends and historic workings associated with silver and antimony mineralisation. Previous exploration at South Star has identified a substantial soil anomaly exceeding one kilometre in length, with rock samples returning impressive grades including 8,760 grams per tonne silver and over 1% antimony, alongside notable gold values. Despite this, the area has seen limited recorded exploration, underscoring the opportunity for discovery as Diablo Resources advances its work.

Exploration Activities Underway

Fieldwork has commenced on the new lease area, with geological mapping and sampling forming part of the ongoing program. Additionally, an induced polarization (IP) survey has been completed over the STAR 01 anomaly at the nearby North Star Prospect, with data currently being processed. These activities are designed to refine target zones ahead of a maiden drilling campaign anticipated in the second quarter of 2026, which will be a critical milestone in testing the project’s resource potential.

Strategic Location and Infrastructure

The Star Range Project benefits from its proximity to historical mining centres such as the Horn Silver Mine and Milford Copper Mine, both within a 15-kilometre radius. The Horn Silver Mine was historically one of the largest silver producers in the United States. Access to the project is facilitated by maintained gravel roads, nearby power lines, gas pipelines, and the Union Pacific Railway, all of which support efficient exploration and potential future development.

Looking Ahead

CEO Lyle Thorne highlighted the strategic importance of the acquisition, noting that the Utah Trust Lands Administration lease consolidates tenure over geology similar to that at South Star and aligns with the company’s ambition to contribute to domestic critical mineral supplies in the US. As Diablo Resources continues to integrate new data and prepare for drilling, the project is positioned to attract further attention in the critical minerals sector, which is increasingly vital for clean energy and technology supply chains.
