Congratulations to Garfield County and Iron County! Trigg Minerals, LLC (DBA American Tungsten and Antimony Ltd, or “ATAA”), a next-generation critical minerals company, has announced plans for new mining operations in Antimony Canyon, Garfield County, alongside a high-tech, clean refining facility planned in Iron County. The project marks a major milestone as Trigg Minerals moves to become the first U.S. producer and supplier of antimony, a critical mineral used in fire retardants, lead-based batteries, and ammunition. Trigg Minerals plans to add 400 new jobs and invest $287 million in Utah, supporting long-term economic growth across rural communities.

“This project represents a significant opportunity for Garfield County and rural Utah as a whole,” said Kaden Figgins, Garfield County director of planning & economic development. “The development of domestic antimony production in Antimony Canyon highlights the strategic importance of our region’s natural resources while creating meaningful economic opportunities for local residents. We appreciate ATAA’s commitment to investing in rural communities and advancing responsible resource development that supports long-term economic resilience, job creation, and national supply chain security.”

“This is a game-changer for our local economy and the future of our residents,” said David Johnson, economic development director of Cedar City and Iron County. “The arrival of Trigg Minerals represents a generational shift for our workforce that will provide hundreds of families with stable, high-paying jobs. We are grateful for this opportunity that ensures a more prosperous and resilient future for all of rural Utah.”

Trigg Minerals is advancing a vertically integrated critical minerals initiative in southern Utah, opening Antimony Canyon in Garfield County to new mining operations while developing a high-tech, clean refining facility in Iron County. This dual-site approach enables in-state extraction and processing, positioning ATAA to become the first domestic producer and supplier of antimony—a material essential to applications such as fire retardants, lead-based batteries, and ammunition.

“EDCUtah is honored to support ATAA as it addresses a critical gap in the U.S. domestic supply chain,” said Ryan Starks, executive director of EDCUtah. “Utah is uniquely positioned to play a meaningful role in the production of critical minerals, and ATAA is helping lead the responsible development of antimony resources. We commend ATAA’s efforts to create high-quality jobs in rural Utah and to advance materials refining through clean, resource-conscious practices.”

“This recognition from the State of Utah represents a major milestone for American Tungsten and Antimony and reinforces the strategic importance of establishing a secure, domestic supply chain for critical minerals in the United States,” said Andre Booyzen, CEO of American Tungsten & Antimony Ltd. “Our planned antimony tertiary refining facility and integrated mining and processing strategy are designed to support America’s growing demand for materials essential to defence, energy, and advanced manufacturing. We are proud to be investing in rural Utah, creating high-quality jobs, and contributing to the long-term economic strength of Iron and Garfield Counties and the wider region. This project reflects our commitment to responsible development, industrial innovation, and helping position the United States as a leader in critical minerals independence at a time when supply chain security has never been more important.”

The Utah Governor’s Office of Economic Opportunity (GOED) assisted the project by approving Trigg Minerals for a Rural Economic Development Tax Increment Financing (REDTIF) incentive.

“Trigg Minerals’ expansion into Garfield and Iron Counties is a monumental win for Utah that perfectly captures the essence of our strategic economic vision,” said Jefferson Moss, commissioner of GOED. “By establishing the nation’s first modern antimony tertiary refining facility right here in our state, we are doing more than just creating 400 jobs in a rural Utah community; we are securing Utah’s position as a critical hub in the global supply chain for defense, renewable energy, and technology. This project exemplifies our commitment to diversifying rural economies and ensuring that Utah leads the way in domestic mineral security and industrial innovation.”

This project was supported by key partners across the state, including GOED, the Utah Inland Port Authority (UIPA), Iron County, the Southern Utah Economic Alliance (So.Utah), BZI, and ARCO Design/Build.
