MP Materials Corporation operates as a vertically integrated producer of rare earth materials in North America. The company owns and manages the Mountain Pass Rare Earth Mine and Processing Facility in California, the only commercially viable rare earth mining and processing site in the United States. MP Materials extracts, separates and refines critical rare earth elements—such as neodymium, praseodymium, and cerium—which are essential inputs for permanent magnets used in electric vehicles, wind turbines, and various defense applications.
The Mountain Pass mine first began commercial rare earth production in the 1950s and was later operated by Molycorp until its bankruptcy in 2015. In 2017, MP Materials acquired the site and rapidly resumed full-scale operations. Since then, the company has invested in expanding its separation and refining capacity, aiming to rebuild a domestic supply chain for rare earth magnets and reduce reliance on foreign sources for these strategic elements.
MP Materials serves customers across North America and exports to global markets, targeting sectors with high growth potential in clean technology and national security. The company is actively developing partnerships to advance downstream processing, including plans for permanent magnet manufacturing in the United States. Through these efforts, MP Materials seeks to strengthen the resilience of critical material supplies and support domestic manufacturing of precision components.
Headquartered in Las Vegas, Nevada, MP Materials is led by a management team with extensive experience in mining, materials processing, and capital markets. Chief Executive Officer James Litinsky, a co-founder of the company, guides strategic initiatives to scale production, optimize operations and expand the company’s value chain. MP Materials continues to invest in operational excellence, environmental stewardship and community engagement as it advances its mission to secure a reliable supply of rare earth materials for the modern economy.
