Markup | Full Committee Hearing

The House Committee on Natural Resources GOP held a full committee markup on September 17, 2025, focusing primarily on legislation to enhance domestic mining and mineral resource development. Key bills considered included H.R. 4090, the Critical Mineral Dominance Act, which codifies aspects of previous executive orders to streamline mining on federal lands, expedite priority projects, and reduce reliance on foreign adversaries for critical minerals. The committee debated amendments addressing environmental safeguards, tribal consultation, and foreign investment restrictions. Another significant bill, H.R. 1366, the Mining Regulatory Clarity Act of 2025, aimed to restore regulatory certainty following the Rosemont court decision by codifying mining support activities and creating an abandoned hardrock mine fund. Both bills were amended and favorably reported out of committee after recorded votes. Additionally, the committee approved a package of six bipartisan bills related to tribal land claims, mineral leasing, and reauthorization of programs supporting fisheries and coastal data. The markup featured extensive discussion on balancing mineral development with environmental protection and community input, as well as concerns about foreign influence in U.S. mining projects.
