Diablo Resources Advances Utah Drilling Preparations at Star Range and Horn Silver
Diablo Resources has completed earthworks at its Star Range Project in Utah, setting the stage for a maiden diamond drilling program targeting high-grade silver and polymetallic mineralisation. Concurrently, the company is progressing its acquisition and exploration activities at the historic Horn Silver Project, with drilling plans advancing.
- Star Range earthworks complete for diamond drilling
- Initial program targets high-grade silver-antimony zones
- Horn Silver acquisition 80% complete with option on patented claims
- Reconnaissance and data integration ongoing at Horn Silver
- Maiden drill programs planned for both Utah projects
Star Range Drilling Ready After Earthworks
Diablo Resources Ltd (ASX:DBO) has finished earthworks at its North Star Prospect within the Star Range Project in Utah, establishing vehicle access and drill pads ahead of a planned diamond drilling campaign. The initial program will comprise five holes totaling approximately 1,000 metres, designed to test multiple polymetallic targets beneath surface anomalies that have yielded spectacular silver grades up to 3,043 g/t (97.8 oz/t) and gold alongside antimony.
This drilling aims to define the scale and continuity of mineralised breccia-vein systems, following extensive surface sampling and coincident geophysical anomalies. The company has already advanced regional exploration with systematic mapping and soil sampling to refine target prioritisation across the district-scale Star Range project.
Horn Silver Acquisition Progresses Towards Drilling
Meanwhile, Diablo has secured an 80% interest in 101 unpatented lode claims at the historic Horn Silver Project and holds an exclusive option over 101 patented claims, with exercise scheduled for completion in September. The project hosts the Horn Silver Mine, a prolific historic producer of approximately 17 million ounces of silver at an average grade of 604 g/t mined from the late 1800s to the 1950s.
Reconnaissance activities have commenced across the unpatented claims, including geological mapping and regional sampling to validate historic workings and refine structural interpretations. Early fieldwork confirms widespread polymetallic mineralisation consistent with a district-scale carbonate-replacement system, featuring silver, antimony, copper, and gold.
Diablo is integrating extensive historical datasets to prioritise near-mine extensions and regional targets such as the Gossan, Drum, and Buckhorn prospects. These targets are supported by geophysical data and historical workings, forming the foundation for the company's maiden drill program at Horn Silver.
Strategic Parallel Advancement of Utah Projects
CEO Lyle Thorne emphasised the significance of advancing both projects simultaneously, noting that with drill-ready access at Star Range and a clear path to finalising Horn Silver’s maiden drill program, Diablo is well positioned to test high-priority targets across two highly prospective mineralised systems. This dual approach underscores the company’s district-scale critical minerals strategy in Utah, aiming to unlock value from both silver-rich projects.
The next steps include commencing drilling at North Star to obtain subsurface geological data beneath high-grade surface samples and geophysical anomalies, while continuing reconnaissance and data compilation across broader Star Range targets. At Horn Silver, the focus remains on completing the option exercise, ongoing regional exploration, and finalising the maiden drilling plan through comprehensive data integration.
Bottom Line?
Diablo’s coordinated push to drill high-grade targets at Star Range and Horn Silver sets the stage for potentially transformative exploration results in Utah’s critical minerals sector.
Questions in the middle?
- Will initial drilling at North Star confirm the continuity of the exceptional surface silver grades?
- How will integration of historic and new data influence drilling priorities at Horn Silver?
- What timeline can investors expect for first assay results from both projects?
