Investment aims to revive domestic production of the critical metal for a decade.
The Department of Defense awarded $6.2 million to Golden Metal Resources on July 22, 2025, to fund a pre-feasibility study for a tungsten mine at Pilot Mountain, southeast of Hawthorne, Nevada.
The funding, drawn from the 2022 Additional Ukraine Supplemental Appropriations Act, supports a March 2025 executive order prioritizing domestic mineral production.
Tungsten, vital for aerospace, vehicles, and munitions, hasn’t been mined in the U.S. for nearly a decade, leaving defense and commercial supply chains vulnerable.
The investment will support metallurgical tests, engineering studies, and environmental assessments to evaluate the site’s viability.
Golden Metal Resources, a subsidiary of Guardian Metal Resources PLC, is one of three tungsten projects backed by the Pentagon since 2024.
“This is a step toward commercial-scale tungsten production,” said Acting Director William Davis, highlighting its role in strengthening national security and industrial resilience.
