DOD issued the award under the Defense Production Act Title III program that aims to ensure the domestic availability of resources essential to national security, the department said Monday.
Military and commercial entities use LREEs for a wide range of applications such as glass additives, vehicle drivetrain motors and petroleum refining.
The future facility would add to Lynas' existing plant operations in Malaysia and Australia. With the new facility, the company's operations would make up a quarter of the globe's rare earth element oxide supply.
The investment is part of Pentagon efforts in support of supply stability and defense supply chain strength.
DOD issued three DPA Title III awards in November 2020 for rare earth element resources.
Other department actions include studying the potential of restarting domestic neodymium-iron-boron magnet production and increasing reliance on non-Chinese providers for rare earth element magnet requirements.
