GAO Audit Reveals Widespread Oversight Gaps in U.S. Hardrock Mining Claims
A new Government Accountability Office audit reveals that the Bureau of Land Management fails to collect or verify citizenship data for hardrock mining claimants on federal lands, creating significant national security and supply chain vulnerabilities for critical minerals.
The Bureau of Land Management (BLM) is failing to enforce statutory U.S. citizenship requirements for hardrock mining claims on federal lands, exposing national security mineral supply chains to unvetted foreign involvement. According to a new report from the Government Accountability Office (GAO), the BLM regularly issues exclusive mineral extraction rights without documenting, collecting, or verifying the citizenship status of individuals or corporate entities holding those claims. In a targeted sample of 15 business entity claimants, GAO auditors found no public evidence of U.S. incorporation for seven entities, a regulatory gap the BLM was unable to resolve due to an institutional lack of baseline ownership data.
Critical minerals—including rare earth elements, cobalt, lithium, and nickel—form the foundation of advanced defense acquisitions, weapons platforms, microelectronics, and tactical energy storage systems. While federal mining laws prohibit foreign entities from directly holding claims, current BLM regulations permit foreign parent companies to establish U.S. subsidiaries without disclosing foreign control, beneficial ownership, or foreign direct investment capital. Consequently, state-owned enterprises or adversary-aligned entities can exploit U.S. public lands to secure mineral assets crucial to the Department of Defense (DoD) supply chain, entirely undetected by federal land managers.
The GAO highlighted stark contrasts between U.S. oversight and the rigorous frameworks deployed by allied nations. Top mineral-producing partners, such as Australia and Canada, systematically track foreign investment in domestic resource extraction. Both nations maintain legal authority to restrict, condition, or block foreign state-owned enterprises and adversarial capital from obtaining controlling interests in critical mineral projects. In contrast, the BLM's failure to capture basic ownership data leaves federal acquisition leaders, defense contractors, and policy makers blind to foreign influence across domestic mineral reserves.
To safeguard federal lands and bolster defense industrial base resilience, GAO recommended that BLM immediately establish mandates requiring staff to collect, document, and verify citizenship and corporate incorporation data for all mining claimants. For defense, government, and aerospace leaders seeking to onshore critical mineral supply chains, this administrative weakness represents an urgent operational vulnerability. Until the Interior Department institutes strict verification protocols, industrial base planners cannot guarantee that U.S.-sourced critical minerals remain free from adversary influence or potential supply chain disruption.
