MP Materials

In 2015, Molycorp, the previous owners of the Mountain Pass mine, filed for bankruptcy. At the time, it was the only U.S. producer of rare earth elements. While in bankruptcy, Secure Natural Resources , a company owned by Molycorp's creditors, including JHL Capital Group, gained control of the mine's mineral rights. In June 2017, the Mountain Pass mine was purchased at auction for $20.5 million by a new entity called MP Mine Operations LLC . MPMO was a consortium formed principally by JHL Capital Group, a Chicago-based investment firm led by James Litinsky, along with QVT Financial LP and Shenghe Resources. Shenghe, a Sichuan China rare earth company, held a minority, non-voting interest. At the time, Mountain Pass was in a state of "care and maintenance" and had only eight employees according to Litinsky.Following the asset acquisitions and formation of the entities that became MP Materials, the company restarted operations at Mountain Pass. On July 15, 2020, the company announced a reverse takeover whereby MPMO and SNR would be merged with Fortress Value Acquisition Corporation to become a public company under the name MP Materials Corp. The transaction, which closed on November 17, 2020, raised $545 million. On November 18, 2020, MP Materials began trading on the New York Stock Exchange under the symbol "MP".

In December 2021, MP Materials signed a long-term agreement with General Motors to provide neodymium-iron-boron magnets for use in GM's electric vehicle motors. As part of the contract, MP Materials also agreed to provide alloy and finished magnets to GM for its electric vehicles and to open a new factory located in Fort Worth, Texas to produce the magnets.As of December 2021, JHL Capital Group, QVT Financial, and CEO James Litinsky were the company's three largest shareholders, and about 7.7% of the company was owned by Shenghe Resources, a Chinese company. Apart from institutions, other investors own 18%.

Mountain Pass mine

Discovered in 1949 in San Bernardino County, California, Mountain Pass mine consists of a bastnäsite ore-body with significant concentrations of rare earth elements. The mine once supplied most of the world's rare earth elements. Mountain Pass is the only operational rare earth mining and processing facility in the United States. The expected Mountain Pass mine life is approximately 24 years.MP Materials produced 28,000 tonnes of rare-earth oxide equivalent from Mountain Pass in 2019, and 38,500 tonnes in 2020, or more than 15% of global production. As of late 2020, Shenghe Resources was the sole purchaser of MP Material's rare earth concentrate.
