Diablo Resources has identified a large, kilometre-scale silver–antimony geochemical anomaly at its 100 per cent-owned Star Range Project in southwestern Utah, USA.
The anomaly was defined following first-pass soil sampling at the South Star Prospect, confirming a coherent silver–antimony trend extending for more than one kilometre and remaining open to the northeast.
The discovery is supported by high-grade rock samples and a series of historical workings, reinforcing geological interpretations that the Star Range Project hosts multiple mineralised vein and breccia systems.
High-grade historical rock samples from the broader Star Range area have previously returned values of up to 8,760 grams per tonne (g/t) silver and greater than 1 per cent antimony.
Recent sampling by Diablo has substantiated these results, confirming zones of elevated silver, antimony, and gold across multiple surface locations.
The company highlighted that the strong spatial correlation between anomalous soil geochemistry and observed surface mineralisation provides a robust vector for continued exploration and target development.
Chief Executive Officer Lyle Thorne said the first-pass results significantly enhanced promise in the company’s geological model and broader exploration potential.
“The results from our first-pass soil sampling continue to build confidence in the potential of the Star Range project,” Thorne said.
“At South Star, the silver–antimony anomaly now extends for more than one kilometre and remains open to the northeast.
“This, combined with several historic workings and high-grade rock samples, reinforces our view that the project hosts multiple mineralised zones.”
Located in a well-established mining district in southwestern Utah, the Star Range Project sits close to areas of historic silver production and near operating copper mines, providing ready access to key infrastructure and a region with a proven mining pedigree.
Diablo maintains a 100 per cent interest in the project, which forms part of the company’s broader strategy to advance exploration and development of US critical minerals projects, including those supplying the growing electric vehicle and renewable energy sectors.
While exploration efforts at South Star continue, the company has also completed ground geophysics at the North Star Prospect, with data processing now underway to refine additional drill targets.
In conjunction with the geophysical program, further geochemical sampling and field mapping are being conducted across several emerging targets within the wider Star Range area.
These parallel work programs are expected to culminate in the final definition of priority drill targets, paving the way for Diablo’s maiden drilling program, which is anticipated to commence in the June 2026 quarter, subject to final target selection and regulatory approvals.
