Summary
Meteoric Resources NL has reported exceptional results from its continuous piloting test work on the Caldeira Rare Earth Ionic Clay Project using ANSTO's facilities. The project, located in Minas Gerais, Brazil, has confirmed high-quality mixed rare earth carbonate (MREC) production with total recoveries of 60% Total Rare Earth Oxide (TREO) and less than 2% impurities. The piloting involved 480 hours of continuous testing over four separate five-day campaigns, validating the process flowsheet for commercial scalability. This collaboration with ANSTO has de-risked the flowsheet using an environmentally friendly ammonium sulfate wash and successfully handled spent clays, which are non-hazardous. This progress supports the ongoing construction of a Brazilian pilot plant set to use these test results and further pilot rare earth oxide separation in collaboration with Metallium Limited and Ucore Rare Metals Inc.
