American Tungsten and Antimony to Acquire Permitted Critical Metals Refinery in Nevada and White Spar Antimony Mine in Arizona

American Tungsten & Antimony Limited has announced the execution of a Share and Purchase Agreement to acquire the Del Sol Refinery in Nevada and the White Spar Antimony Mine in Arizona. The deal, which is structured as a combination of cash and stock, aims to enhance American Tungsten's capabilities in the production of tungsten and antimony products, although the specific financial details of the transaction remain undisclosed. This acquisition was officially announced on July 28, 2026, marking a significant step in the company's strategy to establish a vertically integrated domestic supply chain for these critical minerals.

The Del Sol Refinery is a constructed and permitted facility that is poised to address the limited domestic refining capabilities for antimony in the United States. The White Spar Antimony Mine is expected to provide initial feedstock, enabling American Tungsten to produce antimony metal flake and potentially expand into military-grade antimony products. This move is particularly strategic given the increasing demand for domestic sourcing of critical metals, as emphasized by recent U.S. government initiatives aimed at reducing reliance on foreign supply chains.

The acquisition aligns with broader industry trends that highlight the growing importance of securing domestic sources of critical minerals. Antimony and tungsten are both designated as essential for U.S. national security and advanced manufacturing, and the ongoing geopolitical tensions have underscored the necessity for a reliable domestic supply. By integrating the Del Sol Refinery and White Spar Mine into its operations, American Tungsten is positioning itself to capitalize on these trends and meet the demands of both the defense industry and commercial markets.

American Tungsten's CEO, Casper Adson, noted that the company's plans include leveraging the existing hydromet infrastructure at Del Sol to expand into tungsten APT production. This expansion is seen as crucial for reducing U.S. dependence on foreign entities for these critical materials. The strategic rationale behind this acquisition is further supported by the company's existing portfolio, which includes various antimony and tungsten projects in Utah and Nevada, positioning it as a key player in the domestic supply chain.

As the U.S. government continues to prioritize the development of domestic critical mineral supply chains, American Tungsten's acquisition of the Del Sol Refinery and White Spar Antimony Mine could have significant implications for the mining sector. The company's hub-and-spoke processing and refining strategy not only aligns with government initiatives but also enhances its competitive edge against peers that rely heavily on imported materials. This transaction underscores the ongoing shift towards domestic production capabilities, which is likely to shape the future landscape of the mining industry in the United States.
