Red Mountain Mining, an exploration and development company focused on gold and critical minerals, has announced the acquisition of 87 claims in the Utah Antimony Project in the US.

Located 11km east of Antimony, Utah, the project was secured through direct staking with the US Bureau of Land Management.

The acquisition, totalling A$138,000 ($91,212.2), was fully funded from the company's internal cash reserves.

The company's initial exploration programme aims to map the undercover extensions of north-south structures associated with antimony mineralisation at Antimony Canyon and Dry Wash Canyon, which extend into Red Mountain's claims.

A desktop study is already in progress, assessing available magnetic and topographic data.

This study will be initially reviewed and potentially augmented by high-resolution drone magnetics and surface reconnaissance mapping to confirm the locations of sub-cropping structures.

The preliminary work will help define areas for more intensive follow-up studies including ground electromagnetics, a method that could directly detect sulphide mineralisation beneath shallow cover.

The company is also considering the use of shallow trenching, auger and rotary air blast drilling to effectively test for antimony through the transported cover.

Red Mountain managing director Lincoln Liu said: “The Utah Antimony Project aligns with the US Government’s urgent push to secure its critical mineral supply chains by rapidly building domestic supply.

“Our project lies adjacent to Trigg Minerals’ Antimony Canyon Project, which is leading the way to becoming one of the first significant modern domestic producers of antimony for the US market. We are proud to have an established and highly experienced US-based technical team placing RMX and our shareholders in a tremendous position to rapidly advance our Utah Antimony Project.”
