SPOKANE: Omnia Metals Group Ltd. has entered the U.S. critical minerals sector through a binding agreement to acquire an antimony and silver project in Montana and the direct staking of a rare earth element and gallium project in the same state, the company announced Monday.
The Australian firm (ASX: OM1) said it signed a heads of agreement to acquire a 100% interest in the Stibnite Ridge project in Sanders County, which sits directly adjacent to U.S. Antimony Corp.’s Thompson Falls smelter — the only U.S. Department of Defense-approved, fully integrated antimony mining and processing operation in North America.
Omnia also said it has staked 80 lode mining claims covering approximately 3,024 acres in Ravalli County, naming the project Radix. The claims are adjacent to U.S. Critical Minerals Corp.’s Sheep Creek deposit, which the company called the highest-grade rare earth element and gallium deposit in the United States, with reported grades up to 20.1% total rare earth elements and gallium concentrations reaching 1,370 parts per million.
“These projects mark a transformational entry for Omnia Metals into the USA critical minerals sector,” Executive Director Patrick Glovac said in a statement. “We believe this portfolio provides Omnia with a powerful platform to pursue high-impact exploration and position the company as a participant in the rapidly emerging critical minerals supply chain.”
Gallium, designated a U.S. critical mineral under Executive Order 13817, is essential for semiconductors, radar systems and 5G infrastructure. The United States currently has no domestic primary gallium production and relies entirely on imports, according to the announcement. China, which controls approximately 90% of global gallium supply, imposed export controls on gallium in July 2023.
U.S. Antimony Corp. resumed mining at its adjacent Stibnite Hill deposit in October 2025 using a cut-and-cover method. The company reported that approximately 800 tonnes of visually identified antimony-bearing ore were transported from the site over roughly 45 days ending in late November 2025. Assay results have not yet been released.
Omnia said it has received firm commitments to raise $1.5 million through a share placement to professional and sophisticated investors at $0.02 per share. Directors also indicated they would subscribe for an additional $82,500 in shares.
The company said it plans to begin data compilation, systematic rock chip sampling and drill permitting immediately. The Stibnite Ridge acquisition remains conditional on shareholder approval, with a notice of meeting expected in coming weeks. The Radix project was staked at no acquisition cost and requires no shareholder approval.
Omnia said it is continuing discussions to acquire a third advanced critical minerals project in the United States.
