• IMC Rare Earths released University of Brighton testwork backing in-situ recovery at its Itarantim rare earths project in Brazil.
• Lab work recovered 73% of total rare earth elements tested, excluding cerium, using acidified magnesium sulphate.
• Terbium recovery reached 71.4%; dysprosium recovery reached 70.5%, supporting potential magnet rare earth production.
• Column leaching generated 4,000-8,000 mg/L total rare earth solutions; downstream work recovered up to 86.6% into mixed carbonate.
• Results support a lower-capital development concept using wells instead of excavation; uranium and thorium stayed below detection limits.
