Diablo Resources Limited has identified a large, kilometer-scale silver–antimony geochemical anomaly at its 100 %-owned Star Range Project in Utah, USA, following first-pass soil sampling at the South Star Prospect.
The program has confirmed a silver–antimony soil anomaly extending for more than 1 kilometer, which remains open to the northeast, and is supported by high-grade rock samples and historical workings. Results reinforce the interpretation that the project hosts multiple mineralized vein and breccia systems.
High-grade historical rock samples from the area returned values of up to 8,760 g/t silver and greater than 1 % antimony, while recent sampling by Diablo has confirmed elevated silver, antimony and gold values across multiple locations. The strong spatial correlation between anomalous soil geochemistry and surface mineralization is considered a positive indicator for further exploration.
The Star Range Project is located in a well-established mining district in southwestern Utah, close to historic silver production and currently operating copper mines. Diablo holds a 100 % interest in the project, which is being advanced as part of the Company’s broader strategy targeting U.S. critical minerals.
Diablo’s Chief Executive Officer, Lyle Thorne, said the results significantly enhance confidence in the project’s potential.
“The results from our first-pass soil sampling continue to build confidence in the potential of the Star Range project. At South Star, the silver–antimony anomaly now extends for more than 1 km 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 mineralized zones.”
In parallel, ground geophysics at the North Star Prospect has been completed, with data currently being processed to further refine drill targets. Additional geochemical sampling and field mapping are underway across several priority targets.
Diablo is progressing toward its maiden drilling program, which is anticipated in the June 2026 quarter, subject to final target definition.
