Critical minerals developer Red Mountain Mining has been approved to list on the US OTCQB market, with trading in the company’s RMXFF code scheduled to begin at 9:30 New York time on Monday.
The company said that it had satisfied all requirements and regulatory approvals for the listing, supported by its newly appointed US-based markets advisory team. The move follows strong pre-listing interest, with RMXFF recently trading as high as A$0.40 and recording a volume-weighted average price of A$0.042 since its November 5 update.
Red Mountain noted that last year more than $478-billion in liquidity and volume flowed through the OTC Markets Group’s exchanges, offering increased access to US retail and institutional investors as well as greater visibility within the US critical minerals sector.
Red Mountain holds multiple antimony assets in Tier-1 US mining jurisdictions. Its Yellow Pine antimony project lies less than 2 km from Perpetua Resources’ Stibnite project in Idaho, while the nearby Silver Dollar antimony project hosts historic high-grade antimony results of 17.7% stibnite. The company also pointed to the strategic position of United States Antimony’s antimony and precious metals smelter to the north.
In Utah, the company’s project sits adjacent to Trigg Minerals’ Antimony Canyon project.
In Australia, Red Mountain continues exploration at its Armidale antimony/gold project in New South Wales, where drilling has returned high-grade antimony results of up to 39.3% stibnite. The project is situated west of Larvotto Resources’ Hillgrove project, Australia’s largest antimony deposit.
The company said its board viewed its portfolio as highly strategic, and that Red Mountain was in active discussions with prospective partners to accelerate project development and leverage expertise in navigating US government critical minerals funding.
These discussions are occurring as the US steps up support for domestic supply. The Department of Energy has announced an additional $355-million in funding for critical minerals, aligning with President Trump’s Executive Orders Unleashing American Energy and Immediate Measures to Increase American Mineral Production. In October, the US and Australian governments also signed a Critical Minerals Framework agreement committing each to spending at least $1-billion over the next six months on project investment.
Red Mountain said resolving the US federal government shutdown last week provided renewed clarity for its expansion strategy.
