Olympio Metals Expands US Critical Minerals Footprint with High-Grade Silver and Antimony Acquisition

Olympio Targets US Critical Minerals with High-Grade Assets

Olympio Metals Limited (ASX:OLY) has completed due diligence and moved to acquire two promising mineral projects in the United States: the Raven Silver Project in Montana and the Sawtooth Antimony Project in Idaho. These acquisitions mark a strategic pivot into critical minerals, notably silver and antimony, which feature prominently on the 2025 US Geological Survey’s Critical Minerals List and are central to the US Government’s US$12 billion strategic stockpile initiative.

Raven Project’s Exceptional Historical Grades Highlight Potential

The Raven Silver Project, comprising 27 mineral claims in Montana’s Thompson River mining district, boasts historical production grades that are nothing short of spectacular. The Raven Mine yielded an average silver grade of 2,084 grams per tonne (67 ounces per tonne) alongside 19.51% copper, while the nearby Silver King Mine averaged 996 grams per tonne silver with notable base metals. Mining activity ceased in the 1950s, and crucially, no modern exploration or drilling has been documented since, leaving a vast opportunity for discovery using contemporary techniques.

Located just 45 kilometres from United States Antimony Corporation’s operational smelter and processing facilities in Thompson Falls, the Raven Project benefits from accessible infrastructure, which could facilitate future development. Olympio plans to initiate surface exploration campaigns at Raven to generate new drilling targets, aiming to unlock value from these historically high-grade veins.

Sawtooth Project Offers Untapped Antimony Prospects

The Sawtooth Antimony Project in Idaho encompasses three silver-antimony prospects, Glory Group, Even Chance, and Lone Trail, spread across 80 mineral claims near the historic Sawtooth City mining camp. While historical sampling has identified silver and antimony mineralisation, the absence of documented sampling methodologies and precise assay locations limits immediate resource confidence under modern reporting standards.

Each prospect features geological settings conducive to antimony mineralisation, such as massive sulphide veins and shear zones, but none have undergone modern exploration. This gap presents Olympio with a ground-floor opportunity to apply current exploration methods in a region with known but underexplored critical mineral occurrences.

Consideration and Strategic Implications

Olympio will issue 12.5 million fully paid ordinary shares to Lia Energy Holdings LLC or its nominees as upfront consideration for the acquisition of Idaho Stibnite Corp, the holder of the mining claims. This share issuance reflects a reduction from earlier terms following the removal of two Sawtooth prospects from the deal, signalling a calibrated approach to the acquisition.

Managing Director Sean Delaney emphasised the diversification benefits and geological prospectivity these projects bring to Olympio’s portfolio. The company’s focus on critical minerals aligns with broader geopolitical trends and government incentives aimed at securing domestic sources of strategic materials.

Next Steps in Exploration and Market Watch

Olympio is collaborating with Scout Discoveries Corp to conduct ground reconnaissance mapping and sampling, prioritising the Raven and Silver King mines. The market can expect updates as surface exploration progresses and new drilling targets are defined. Given Olympio’s recent momentum in gold-focused drilling programs, this critical minerals expansion represents a notable diversification of its exploration pipeline.
