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.
For years, China has dominated global tungsten supply, controlling more than 80 percent of both mining output and downstream processing. It also consumes the lion’s share of its own production, effectively bottlenecking availability for Western markets. That stranglehold has tightened in recent months with Beijing’s February 2025 export restrictions, which sent shockwaves through critical mineral markets. Since 2016, no commercial tungsten concentrate has been produced in either the U.S. or Canada. Today, North American demand exceeds $1 billion annually, with prices continuing to rise as global supply chains fragment.
USAC isn’t stepping into this space blindly. The company has cited prior data from SRK Consulting which confirms an inferred resource of 12.4 million tonnes of ore grading 0.213 percent tungsten trioxide at the Fostung site. Those numbers were compiled under Canadian NI 43-101 standards. A new report compliant with U.S. SEC SK-1300 regulations is now in the works and will incorporate drill results from more recent exploration programs conducted by previous property holders.
What makes the play even more compelling is the potential for on-site beneficiation. USAC plans to evaluate advanced ore sorting technologies based on tungsten’s distinct fluorescent and physical properties, with the aim of producing a higher-grade concentrate directly at the property. If successful, that concentrate could be trucked to existing Canadian or U.S. mills for final processing. Conventional flotation milling near the site remains a fallback option, but the push is clearly toward innovative low-footprint solutions that can be deployed quickly.
The geology of the region aligns with USAC’s broader critical mineral strategy. The Fostung deposit sits within the Espanola Formation, part of the ancient Huronian meta-sedimentary belt, similar to the company’s Iron Mask cobalt property northwest of Sudbury. This geological continuity provides a layer of technical confidence and hints at broader resource synergies. The company is betting that Fostung can become a cornerstone asset in its critical mineral portfolio, supporting both strategic and commercial objectives in a world that increasingly values domestic resilience over global dependency.
The acquisition also highlights USAC’s broader operational footprint. Beyond antimony and precious metals recovery at facilities in Montana and Mexico, the company operates Bear River Zeolite in Idaho, a facility central to U.S. environmental remediation and agricultural industries. These diversified assets underscore a key principle behind the Fostung move: critical minerals are no longer just a commodity—they’re a matter of national interest. And the market knows it.
Price trends have only reinforced that urgency. USAC’s internal data analysis—backed by Argus Media, compared Chinese tungsten bar prices delivered to the U.S. with Rotterdam-based ingot prices over the last four years. The result is a pattern of relentless volatility, with Chinese prices consistently elevated due to logistics challenges, tariffs, and export controls. Even European pricing has felt the shockwaves, illustrating just how interlinked and fragile the supply web has become. In such an environment, securing a domestic or allied source of tungsten isn’t just smart, it’s essential.
The structure of the acquisition itself is telling. In addition to the $5 million upfront payment, a small Net Smelter Return royalty was retained by the sellers, Transition Metals Corp and 1930153 ON Ltd. Transition, a publicly traded Canadian exploration firm known for its geoscientific depth and early-stage project pipeline, shares the royalty with the privately held Sudbury-based firm. The shared royalty suggests both confidence in the deposit’s economic viability and a spirit of collaboration that bodes well for future development.
As the critical mineral race accelerates, USAC’s move is likely to resonate far beyond Ontario. Tungsten may not have the pop-culture cachet of lithium or the tech magnetism of rare earths, but its role in national defense, high-performance manufacturing, and strategic technology cannot be overstated. The Fostung acquisition is not just a bet on a deposit, it’s a declaration of intent. It signals that U.S. Antimony is ready to play a leading role in the North American critical minerals resurgence, one strategic acquisition at a time.
Conclusion
United States Antimony’s acquisition of the Fostung Tungsten Property in Ontario is more than just a corporate milestone. It’s a strategic move that speaks volumes about where the world, and particularly North America, is heading when it comes to resource security. In a world increasingly divided by geopolitical lines and fractured supply chains, tungsten has emerged as a quiet giant. With prices climbing, Chinese exports tightening, and no domestic production to speak of, USAC’s entry into the tungsten sector feels less like a pivot and more like a long-overdue correction. Backed by robust geological data, local infrastructure, and the promise of innovative processing, Fostung may soon go from inferred resource to critical national asset. The stakes are high, but so is the upside.
