Diablo Resources Limited (ASX:DBO) has identified high-priority drill targets at its 100% owned Star Range Silver-Antimony Project in Utah, following completion of an Induced Polarisation (IP) survey at the North Star Prospect.
The survey has outlined multiple chargeability and conductivity anomalies that coincide with known high-grade surface mineralisation and favourable geological structures, supporting the Company’s plans for a maiden drilling program in Q2 2026.
The newly defined targets align with the STAR-01 magnetic anomaly and are located proximal to an intrusive–sediment contact, a setting recognised as highly prospective for mineralisation.
Surface sampling at North Star has previously returned high-grade results including up to 3,043 g/t silver and 0.7% antimony, reinforcing the prospectivity of the system.
Importantly, the target area remains untested by drilling, presenting a first-mover opportunity to evaluate the scale and continuity of the mineralised system.
The IP program, comprising approximately 9 line-kilometres of surveying, has defined three priority drill areas targeting chargeability and conductivity anomalies interpreted to be associated with sulphide mineralisation at depth.
Planned drilling will also test high-grade veins and breccia zones identified at surface, forming the foundation of Diablo’s maiden drill campaign.
CEO Lyle Thorne commented:
“We are very encouraged by the results of the IP survey completed at North Star. The survey has outlined clear anomalies of interest that coincide with known mineralisation and highly prospective geological settings, further reinforcing our view that the North Star Prospect represents a priority drill target.
The addition of these new geophysical targets provides valuable flexibility in shaping our exploration strategy as we progress toward our maiden drill program.
Silver is increasingly recognised both as a precious and strategic metal, with growing demand from defence systems, electric vehicles, solar panels, AI data centres, and 5G infrastructure. We are committed to participating in the United States’ domestic efforts to secure reliable supplies of critical minerals.”
The Star Range Project is located in Beaver County, Utah, approximately 6km from the town of Milford and near historical and operating mining centres, including the Horn Silver Mine and Milford Copper Mine.
The region has a long history of base and precious metals production and hosts favourable geology including structurally controlled mineralisation and intrusive-related systems.
Next steps include finalising drill program design and logistics, submitting permitting applications, and continuing regional geochemical exploration across the broader project area.
