Perth, Australia | 14 January 2026 – Diablo Resources Limited (ASX:DBO; OTCQB:DBORF) has reported further high-grade surface assay results from its 100%-owned Star Range Critical Minerals Project in Utah, USA, confirming multiple polymetallic systems prospective for silver, antimony, copper and gold and strengthening the case for maiden drilling.
The latest reconnaissance rock sampling has returned standout results including silver grades of up to 880 g/t, copper up to 7.4%, gold up to 9.3 g/t, and antimony up to 0.6%, extending known mineralised trends and identifying several new prospect areas across the project.
Results confirm multiple high-grade mineralised systems across Star Range, with the North Star Prospect emerging as a priority drill target. Surface sampling has now defined mineralised breccia and vein trends over more than 3,000 metres, which remain open along strike.
New prospect areas identified include East Star, where skarn-style mineralisation has returned peak results of 7.4% copper, 300 g/t silver and 1.4 g/t gold, and West Star, which has delivered silver grades of up to 692 g/t. Sampling has also extended mineralisation at the Silver Gulch Prospect, where a mineralised trend now exceeds 900 metres in length.
Diablo Chief Executive Officer Lyle Thorne said the results marked a significant milestone for the project.
“These latest results represent a pivotal step forward for the Star Range Project. We have successfully extended mineralisation at our key prospects and, importantly, identified entirely new zones such as East Star, West Star and Silver Gulch, confirming the project hosts multiple polymetallic systems prospective for silver, copper, and antimony.
North Star is rapidly taking shape as an incredibly exciting drill target. The combination of highgrade surface results, extensive strike continuity and multiple mineralised styles gives us confidence in the scale potential of the system.
With geophysical interpretation nearing completion and further results pending from ongoing fieldwork, we are progressing steadily toward our maiden drilling program.”
The Star Range Project is located approximately 6 kilometres west of Milford, Utah, within a historically productive mining district that hosts numerous past-producing silver and copper operations, including the Horn Silver Mine. The project benefits from excellent infrastructure access and is situated in a Tier-1 mining jurisdiction.
Drill targeting is now well advanced, with interpretation of airborne magnetic data nearing completion and the permitting process for first-pass drilling underway. Diablo expects to integrate geophysical results with surface geochemistry and mapping to prioritise drill-ready targets, with North Star a key focus.
The Company noted a supportive market backdrop for the targeted commodities, with strong demand fundamentals and supply constraints driving recent price strength in silver, copper and antimony.
Further results from additional rock samples currently at the laboratory are expected to assist with ongoing target refinement as Diablo advances the project toward maiden drilling.
