Diablo’s U.S. Expansion Faces Crucial Test as Key Assay Results Await

Exploration Momentum at Star Range

Diablo Resources has made a striking entrance into the U.S. critical minerals arena with its Star Range Silver-Antimony Project in Utah. Since acquiring the project in October 2025, the company has rapidly expanded its footprint from 104 to 186 lode claims, covering approximately 14.5 square kilometres. Early reconnaissance rock sampling has yielded exceptional silver grades, with assays reaching up to 3,043 grams per tonne at the North Star prospect and bonanza silver grades of 8,760 g/t previously recorded at South Star. Antimony, a critical mineral often overlooked in historical data, has been confirmed at significant levels exceeding 1% in some samples, highlighting the project's polymetallic potential.

Complementing the sampling, a drone aeromagnetic survey was completed, promising to refine targeting and reveal new mineralised zones. The integration of high-resolution magnetic data with geological mapping is expected to sharpen exploration focus in the coming months, with further rock sample results pending.

Encouraging Copper Results at Phoenix

At the Phoenix Copper Project, also in Utah, Diablo has reported promising drill results from its maiden reverse circulation program. Notably, drill hole PHIL25-10 at the Philadelphia prospect intersected 10.5 metres grading 1.02% copper, including a high-grade 1.5-metre interval at 3.99% copper. These results validate the prospectivity of the fault-controlled mineralisation and set the stage for ongoing drilling at both Philadelphia and the nearby Fair Dinkum prospect, where assays from 10 holes drilled late in 2025 are awaited.

Surface sampling at Fair Dinkum has already returned strong copper and silver grades, with several rock grabs exceeding 1% copper. The project benefits from proximity to known mineralised structures and historical workings, underscoring its potential as a significant copper discovery.

Corporate Developments and Market Access

Supporting its aggressive exploration agenda, Diablo successfully raised $2 million through a placement to professional and sophisticated investors. This capital injection is earmarked to accelerate activities across its U.S. projects and explore additional critical minerals opportunities. The company also commenced trading on the OTCQB market under the symbol DBORF, enhancing liquidity and accessibility for U.S. investors by enabling trading in U.S. dollars during American market hours.

Corporate governance has been bolstered with the appointment of Matthew Blumberg as a Non-Executive Director. Blumberg brings valuable investment and resource sector expertise, particularly with his U.S.-based perspective, which aligns well with Diablo’s expanding American footprint. Meanwhile, investor relations efforts have been strengthened by the addition of Ellis Martin, a seasoned U.S. media and communications advisor, aiming to raise the company’s profile across North American markets.

Looking Ahead

With high-grade silver-antimony assays confirming the Star Range project's potential and copper drilling at Phoenix delivering encouraging early results, Diablo Resources is positioning itself as a notable player in the U.S. critical minerals sector. The pending assay results from ongoing drilling and the interpretation of the aeromagnetic survey will be pivotal in defining the next phase of exploration and potential development.
