MP Materials

Owner and operator of Mountain Pass mine, the only Rare Earth mining and processing site in North America

Rare Earths power the modern economy. They are essential components in a wide range of industrial, clean energy and information technology applications. Mountain Pass’ bastnaesite ore is one of the world’s highest quality Rare Earth deposits. The mine started production in 1952, and, from the 1960s through the mid-1980s, it was the dominant source of Rare Earth minerals in the world. More recently, Chinese Rare Earth production has grown to account for 85% of the global supply, and Rare Earths mining and processing stopped in the United States. MP Materials is re-emerging as a best-in-class, globally competitive Rare Earths producer aiming to be a reliable and trusted partner in America’s next generation manufacturing supply chain.
