NEW YORK, July 28, 2026 /PRNewswire/ -- American Tungsten & Antimony Limited (ASX: AT4; OTCQB: ATALF) 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 agreement consists of a combination of cash and stock.

"The Del Sol Refinery is a constructed and permitted antimony refinery in a market with minimal domestic capability," said Casper Adson, AT4 CEO. He noted that the mine, with initial feedstock from White Spar and Antimony Canyon can provide At4 with the ability to produce antimony metal flake and a roadmap into military specification antimony products domestically in the U.S. "Based on Del Sol's hydromet infrastructure, we are immediately planning for expansion into tungsten APT production with an aim of reducing U.S. reliance on this critical metal from Foreign Entities of Concern."
Tim Morrison, executive chair of At4 noted: "Our closest US-listed peer, United States Antimony Corp., relies substantially on ore sourced from outside the U.S. We believe that Del Sol has the ability to deliver to us a pathway to similar refining capability, with feed sourced from U.S. domestic sources, thereby allowing us to develop a true mine-to-metal American supply chain." He added that this comes at a time when Presidential Executive Order has mandated the defense industry to procure antimony, tungsten and other critical minerals, to shift their procurements to domestic suppliers where possible.
American Tungsten & Antimony (https://www.ataa.com) continues to advance a portfolio of antimony and tungsten projects in Utah and Nevada. Both minerals are designated as critical to U.S. national security, defense and advanced manufacturing. The company's portfolio includes the flagship Antimony Canyon Project in Utah, together with a portfolio of tungsten projects across Utah and Nevada, including Tennessee Mountain, Fraction Lode, Nightengale, Sage Hen and Dutch Mountain. The company is pursuing a U.S.-based hub-and-spoke processing and refining strategy aligned with U.S. government priorities for the security of domestic critical minerals supply chains.
