The agreement, finalized on July 28, 2026, involves a mix of cash and stock to bring the Del Sol facility under company control. CEO Casper Adson identified the refinery as a rare, permitted asset in a market currently lacking domestic antimony processing capabilities. The company plans to leverage the site’s existing hydromet infrastructure to produce antimony metal flake, with a secondary phase focused on expanding into tungsten APT production.

American Tungsten & Antimony Targets Domestic Supply Chain Independence
With a dual acquisition in Nevada and Arizona, American Tungsten & Antimony is moving to secure domestic processing for two critical minerals. By purchasing the Del Sol Refinery and the White Spar Antimony Mine, the company aims to bypass foreign reliance for components essential to U.S. defense and advanced manufacturing.

Executive chair Tim Morrison emphasized that the strategy is designed to create a "mine-to-metal" American supply chain, contrasting the firm’s approach with peers who rely on imported ore. This move aligns with recent federal mandates requiring the defense industry to prioritize domestic sources for critical minerals. In addition to these new assets, the company continues to develop its flagship Antimony Canyon Project in Utah and several tungsten sites across Nevada and Utah, positioning itself as a key supplier for U.S. national security interests.
