  • The issue poses a vulnerability for U.S. supply chains and is a potential national security risk.
  • Mountain Pass (M.P.) Materials, the largest rare earth mine in the U.S., is building a rare earth refinement facility.
  • The U.S. Defense Department awarded M.P. Materials a $35m contract in February 2022 to process heavy rare earth elements.
