Nova Minerals announced late Tuesday that it has received final approvals from the Alaska Department of Natural Resources for the plan of operations and reclamation plan for its Department of War-funded antimony project, completing the project's permitting process and clearing the way for construction and development activities. "Securing our final permits is a major milestone for Nova, moving our Alaska antimony project from development planning toward construction and targeted production in 2027."
In 2025, Nova secured a land use permit for its proposed antimony refinery in Alaska. The Australia-based company said the land use permit would allow it to establish downstream antimony processing and refining operations in Alaska's Mat-Su Borough, an area with ready infrastructure for rapid development. The refinery site at Port Mac is strategically aligned with the fast-progressing West Susitna Access Road and other regional development projects currently underway, it said.
Nova said it has secured all required permits within approximately three months of submission and can proceed with Phase 1 of its Alaska antimony development, advancing the establishment of the first modern, fully integrated U.S. domestic antimony supply chain in decades.
The proposed refinery represents the next phase of Nova's strategy of onshoring U.S. antimony production by building a fully integrated, mine-to-processing production hub in Alaska. Its Port Mac facility is expected to produce a full range of antimony products, including antimony trisulfide, antimony trioxide and antimony metal, used by both the U.S. military and in industrial applications.
Anchoring this strategy is the company's district-scale, 10-million-oz. Estelle gold project. Historically, antimony mining in Alaska has been associated with its large gold deposits. The Estelle project is located within the Tintina gold belt, known to host significant antimony deposits in the past and once a supply of the mineral to the North American market.
