Bill overview
The Critical Mineral Dominance Act aims to strengthen the United States’ ability to produce hardrock minerals, including rare earth elements, by accelerating mining operations on federal lands. It directs the Department of the Interior to identify and expedite projects, review existing regulations that may hinder mining, and assess the economic impact of relying on mineral imports. The bill also mandates a review of state and local laws that could impede domestic mining development and prioritizes expanding geologic mapping efforts to locate new mineral deposits.
