Diablo Resources

What Diablo Resources does

Diablo Resources Limited is an Australian-domiciled, ASX-listed (DBO) and OTCQB-listed (DBORF) mineral exploration company focused on copper, gold, silver, and antimony projects in the United States. The company was incorporated and listed in 2021 and is headquartered in West Perth, Australia, with all exploration assets located in Utah and Idaho. Diablo holds three 100%--owned projects: the Phoenix Copper Project and Star Range Silver-Antimony Project, both in Utah, and the King Solomon Gold Project in Idaho. Phoenix Copper sits along strike from the operating Lisbon Valley Copper Mine (270 Mlb resource), while King Solomon lies 10 km west of the Beartrack Mine (+1 Moz gold) in Lemhi County.

The company's core technology is conventional mineral exploration: HQ3 diamond drilling, reverse circulation drilling, stream, soil and rock geochemical sampling, geological mapping, and alteration zone identification targeting sediment-hosted copper, gold-quartz vein, and manto/breccia silver-antimony deposit styles. It has no proprietary software platform; rather, its technical edge is the combination of district-scale land tenure (approximately 8,960 acres of unpatented lode claims), historical high-grade surface samples (up to 8,760 g/t Ag and 65.6 g/t Au), and proximity to operating mines that provide geological analogues. Recent operating activity includes a 646 m maiden drill program at Phoenix Copper in late 2025 and the November 2025 commencement of maiden drilling at the Fair Dinkum Prospect following copper's addition to the U.S. Critical Minerals List.

Diablo's business model is pre-revenue equity-funded exploration. It generates no operating cash flow; capital is raised through periodic ASX equity issuances to fund drilling, assaying and corporate overhead. There are no products sold, no offtake agreements, no streaming arrangements, and no resource estimates disclosed. The go-to-market is investor relations targeted at Australian retail and institutional investors via the ASX platform and, more recently, at US investors via the OTCQB listing. End customers, in the eventual commercial sense, would be copper, silver, antimony and gold offtakers or downstream producers, but the company is several years and multiple drilling/resource milestones away from that stage.

Core offering

Diablo Resources is a pre-revenue mineral exploration company that discovers and advances copper, gold, silver, and antimony deposits in the western United States. It operates three 100% owned projects — the Phoenix Copper Project in Utah, the King Solomon Gold Project in Idaho, and the Star Range Silver-Antimony Project in Utah — using diamond drilling, RC drilling, geochemical sampling, and geological mapping. The company funds exploration through periodic equity capital raisings on the ASX and OTCQB markets.

Product overview

Diablo Resources Limited is a mining exploration company focused on the discovery and development of major copper and gold deposits in North America. The company operates three 100% owned projects: the Phoenix Copper Project (copper exploration in Utah), the King Solomon Gold Project (gold exploration in Idaho), and the Star Range Silver-Antimony Project (silver and antimony exploration in Utah). These projects span the exploration pipeline from early-stage targets to advanced drilling programs at prospects like Philadelphia and Fair Dinkum.

Products and services

• Phoenix Copper Project A copper exploration project in Utah located along strike and within the same geological sequence as the operating Lisbon Valley Copper Mine (270 Mlb copper resource, the second largest copper mine in Utah). The project is prospective for sediment-hosted copper deposits (Lisbon Valley-style) and includes the Philadelphia and Fair Dinkum prospects, with mineralisation associated with the regionally significant Philadelphia Fault and the Flying Diamond Fault system.
• King Solomon Gold Project A gold exploration project located 10 km west of Salmon in Lemhi County, Idaho, in a prolific gold mining district that hosts the Beartrack Mine (+1 Moz). The project hosts precious metal occurrences including the Lone Pine Vein Zone and King Solomon Prospect, with mineralisation in highly altered quartz veined zones in both metasediment and intrusive rocks spatially related to the Eocene age Trans-Challis Fault System. Historical intercepts include 52m @ 2.6 g/t Au and high-grade results including 65.6 g/t Au.
• Star Range Silver-Antimony Project A silver-antimony exploration project in Utah covering approximately 2,100 acres, consisting of the North Star and South Star Prospects. Historical rock sampling includes bonanza silver grades up to 8,760 g/t Ag (309 oz/t) and antimony >1% Sb at surface, with historical soil programs delineating large silver anomalies of 1.5 km at North Star and 400 m at South Star. Manto-replacement and breccia vein system exploration targets high-grade silver and antimony mineralization.

Quantifiable outcome

• Drilling intercept: 10.5m @ 1.02% Cu from 36.5m including 1.5m @ 3.99% Cu at Philadelphia Prospect

Broad incumbents

• Cobalt Blue Holdings: ASX-listed (ASX:COB) company focused on cobalt and critical minerals with an established project portfolio. Larger and more advanced than Diablo, but operates within the same critical minerals policy-driven investment thesis that benefits domestic critical mineral development.
• Freeport-McMoRan: Major US-headquartered copper producer (NYSE:FCX) with significant Arizona copper operations. Provides context for the broader US copper industry and represents a potential acquirer of advanced-stage copper projects like those Diablo is exploring in Utah.
