Once operational, feedstock for the facility will be sourced from the Lynas Mt Weld rare earths deposit and Kalgoorlie Rare Earths Processing Facility in Western Australia. Mt Weld is recognised as a world-class source of light and heavy rare earth minerals. The US facility will be able to process feedstock from other sources if and when they become available and are qualified.“We are delighted to work with the U.S. DoD to deliver our US heavy rare earths separation plant in Texas, which is a key pillar of Lynas’s growth strategy,” said Amanda Lacaze, CEO and Managing Director, Lynas Rare Earths. “This further support by the DoD demonstrates the priority being given to developing robust and resilient rare earth supply chains.

If Halleck Creek proves to be substantial for the supply of heavy rare earths in the future we will be on the radar for additional feedstock IMO
