The U.S. Department of Agriculture’s Forest Service today issued the final record of decision for the Hermosa Critical Mineral Project, marking a major accomplishment in the agency’s effort to strengthen domestic mineral production. The decision, completed in record time as a FAST 41project, supports President Trump’s goal of increasing mineral independence and bolstering the nation’s energy and economic resilience.
South32 Hermosa Inc., an Australia-based mining and metals company, is proposing a $2.16 billion mining and processing operation in a historic mining district in Santa Cruz County, Arizona, near the U.S.–Mexico border. The project is expected to create up to 900 direct jobs and thousands more through indirect economic activity, with a goal of hiring 80 percent of its workforce locally.
“President Trump has launched an all of government mandate to strengthen and secure America’s critical minerals supply chains. The Hermosa Critical Minerals Project shows how increasing domestic production can reduce our dependence on vulnerable foreign sources, and power modern industries, advanced technologies, and essential infrastructure,” said Secretary Brooke L. Rollins. “With one of the world’s largest undeveloped zinc resources and key minerals such as zinc and manganese, it’s a strategic investment in America’s energy and manufacturing future. This project will support nearly a thousand American jobs and bring billions to the local community. We will continue to move at Trump speed responsibly approving these projects to support economic stability, and enhance national security.”
The Hermosa project represents a major economic and strategic opportunity for the United States. As home to one of the world’s largest undeveloped zinc resources—and minerals essential for steel production and large‑capacity batteries—it is a critical investment in the nation’s energy and manufacturing future.
At a time when the United States remains heavily dependent on mineral imports that are vulnerable to long‑term disruptions, the Hermosa Project strengthens national security, supports economic stability, and improves supply chain resilience.
The project advances Executive Orders 14154 (Unleashing American Energy), 14156 (Declaring a National Energy Emergency), and 14241 (Immediate Measures to Increase American Mineral Production), by increasing domestic mineral production, reinforcing critical infrastructure, and ensuring reliable access to minerals needed for defense readiness and modern industry.
“The Coronado National Forest has successfully met all FAST-41 Act milestones. Issuance of the record of decision signals the conclusion of the National Environmental Policy Act process,” said Coronado National Forest Supervisor Kerwin S. Dewberry. “The next steps for South32 Hermosa include submitting the financial assurance and the final Mine Plan of Operations. The final authorization is scheduled to be issued on Friday, Sept. 4, 2026.”
The final environmental impact statement, final record of decision, and other related documents are available online on the Hermosa Critical Minerals Project webpage.
