American Tungsten and Antimony (OTCQX: ATALF) has engaged Metso Finland Oy to complete a FEL1-level Scoping Study for an ammonium paratungstate (APT) production circuit at the Del Sol Refinery in Amargosa Valley, Nevada. The study is based on a proposed Phase 1 design capacity of 2,500 tons per annum of tungsten APT and will outline a potential Phase 2 modular expansion to 5,000 tons per annum.
According to American Tungsten and Antimony, installing an APT circuit within the existing, constructed and permitted Del Sol hydrometallurgical antimony plant could lower capital needs and shorten the timeline to domestic tungsten production. The company has announced a Share and Purchase Agreement to acquire 100% of the Del Sol Refinery and the White Spar Antimony Mine, complementing its antimony and tungsten project portfolio across Utah, Nevada and Arizona, and aligning with July 2026 U.S. Executive Order 14415 favoring domestic sourcing of critical minerals.
American Tungsten & Antimony (OTCQB: ATALF) reported that its wholly owned US subsidiary, Trigg Minerals (USA), has been selected by the U.S. Department of Energy to begin negotiations on the scope and terms of a potential award of up to US$18 million for the ASCEND-Sb antimony smelting project. The project is one of nine chosen under a broader US$162 million DOE program administered by the Advanced Mining and Mineral Production Technologies Office. According to the company, this marks an initial step toward securing grant funding to support a mine-to-metal American antimony supply chain. The company also highlights its portfolio of antimony and tungsten projects in Utah and Nevada and a July Share and Purchase Agreement to acquire 100% of the Del Sol Refinery in Nevada and the White Spar Antimony Mine in Arizona.
American Tungsten & Antimony (OTCQB: ATALF, ASX: AT4) has executed a Share and Purchase Agreement to acquire the Del Sol Refinery in Nevada and the White Spar Antimony Mine in Arizona, using a combination of cash and stock.
According to American Tungsten & Antimony, Del Sol is a constructed and permitted antimony refinery in a U.S. market with limited domestic refining capability. Initial feedstock is expected from White Spar and the company’s Antimony Canyon project, enabling production of antimony metal flake and a pathway to military-specification antimony products within the U.S.
The company also plans to expand Del Sol’s hydrometallurgical infrastructure into tungsten APT production to reduce U.S. reliance on foreign sources. Management highlights this as supporting a mine-to-metal American supply chain amid U.S. government directives favoring domestic sourcing of critical minerals, complementing its existing antimony and tungsten projects in Utah and Nevada.
American Tungsten & Antimony (OTCQB: ATALF) appointed former U.S. Secretary of the Interior David Bernhardt as Chairman of its Strategic Advisory Board on May 7, 2026.

Bernhardt served as Secretary of the Interior overseeing federal land and permitting frameworks relevant to U.S. mining and critical-minerals supply chains.
