US Antimony Taps Canadian Tungsten to Tackle Global Shortages
US Antimony stakes its claim in Ontario’s tungsten-rich terrain, igniting a North American push to reclaim control of critical mineral supply chains amid rising geopolitical tensions and Chinese export restrictions.

In a move that underscores the rising urgency for secure critical mineral supply chains across North America, United States Antimony Corporation has officially announced its acquisition of the Fostung Tungsten Property in Ontario, Canada. The Dallas-based company, trading under the NYSE American ticker UAMY, secured 100 percent ownership of the mineral-rich property near Espanola, west-southwest of Sudbury. With a $5 million price tag and a minor royalty arrangement, the acquisition positions USAC at the center of a resurging tungsten market that has grown increasingly constrained by geopolitics and tightening Chinese exports.
The Fostung property, located in one of Canada’s most prolific mining belts, spans fifty single-cell claims across more than 1,100 hectares of terrain. For a company that has historically focused on antimony, zeolites, and precious metals, this marks a pivotal strategic expansion into the tungsten space. According to Executive Vice President and Chief Mining Engineer Joseph Bardswich, the acquisition meets all criteria for fast-track development, citing strong local infrastructure, ease of access, and proximity to power and skilled labor. The site is flanked by the Sagamok and Whitefish First Nations, and sits less than 100 kilometers from Sudbury’s mining hub.
But it’s not just about the ground game. It’s about the metal. Tungsten isn’t your average industrial mineral. With the highest melting point of all elements, coupled with exceptional hardness and density, tungsten has become indispensable to industries spanning aerospace, defense, electronics, energy, manufacturing, and medical technology. From kinetic energy penetrators and tank counterweights to semiconductors and radiation shielding, the metal’s unique profile makes it impossible to substitute in high-stress applications. And therein lies the opportunity, and the risk.
