IMC Rare Earths Ltd announced a new shallow, terbium-rich ionic clay discovery at Block H, outside its existing 1.1 billion tonne Mineral Resource. Hole AD-00555 intersected 7.0 meters of continuous mineralization from 2.0 to 9.0 meters below surface; the included 3.0-meter interval averaged 52 ppm Tb4O7, and a 1-meter sample returned 58 ppm. Initial testing recovered 64% to 83% of terbium from the upper three meters of the enriched zone.
At Block D, hole AD-00403 intersected 20.0 meters of continuous mineralization, including 9.0 meters averaging 24 ppm Tb4O7 with 72% average terbium extraction. IMC plans diamond drilling to test the zone at greater depth. The potential quantity and grade at Blocks H and D are conceptual, and exploration is insufficient to estimate a mineral resource in either area; no economic study has been completed on Block H.
IMC Rare Earths Ltd (IMC) reported metallurgical test results from the University of Brighton indicating that rare earths from its Itarantim Project in Brazil may be amenable to in-situ recovery (ISR), a concept that could reduce excavation, tailings and capital intensity if confirmed at field scale.
Laboratory work using acidified magnesium sulphate recovered 73% of total rare earth elements tested (excluding cerium), including 71.4% terbium and 70.5% dysprosium, and generated rare-earth-bearing solutions of 4,000–8,000 mg/L. Downstream processing recovered up to 86.6% of rare earths from solution to produce a mixed rare earth carbonate, then a mixed rare earth oxide containing about 41% total rare earths. Uranium and thorium remained below detection limits in leach solutions under tested conditions. IMC plans hydrogeological, pilot injection and recovery testing and further engineering studies to evaluate ISR at Itarantim, which hosts an approximately 1.1 billion tonne Inferred Mineral Resource of rare earth-bearing ionic adsorption clay.
IMC Rare Earths Ltd (IMC) reports laboratory-scale metallurgical testwork results from its Itarantim ionic adsorption clay rare earth project in Brazil, highlighting terbium recoveries of up to 95.2% and the successful production of a mixed rare earth carbonate using an optimized hydrometallurgical route.
The project hosts approximately 1.1 billion tonnes of Inferred Mineral Resource containing all four principal magnet rare earth elements, with material in a 105.8 million tonne inferred domain averaging 8 ppm terbium. Average recoveries for magnet rare earth oxides included 66.1% for neodymium, 36.5% for praseodymium, 46.1% for dysprosium and 81.1% for terbium. All resources are classified as Inferred, which are considered too speculative for economic evaluation and do not have demonstrated economic viability. IMC has engaged ANSTO Minerals for the next phase of metallurgical work to further quantify recovery performance and support evaluation of potential development pathways.
IMC Rare Earths Ltd (IMC) is registering the resale of 10,110,000 ordinary shares underlying warrants held by Americas Rare Earths Holdings Ltd., an entity wholly owned by CEO and Chair Francesco Scolaro. These are secondary sales; IMC will not receive any proceeds from resales by the selling shareholder.
After this offering there will be 115,810,000 ordinary shares outstanding, and the registered shares will represent a considerable percentage of the public float. IMC warns that substantial sales under this prospectus could significantly depress its share price and impair its ability to raise capital, while the selling shareholder may still realize gains due to its lower acquisition cost.
IMC is an exploration-stage rare earth company focused on the Itarantim Project in Brazil, with an inferred mineral resource of 1.1 billion tonnes at 1,233 ppm TREO and no current operating revenue. For the year ended March 31, 2026, it recorded a loss of $3.16 million and a total equity deficit of $7.09 million, and discloses substantial doubt about its ability to continue as a going concern. IMC is an emerging growth company, a foreign private issuer, and a controlled company, with Mr. Scolaro and affiliates controlling about 68% of voting power, allowing reliance on reduced reporting and corporate governance requirements.
IMC Rare Earths Ltd, a Cayman Islands company focused on Brazilian rare earth exploration, has filed a Form F-1 resale prospectus covering 10,110,000 ordinary shares underlying warrants held by Americas Rare Earths Holdings Ltd. All shares are being registered for resale; the company will not receive proceeds from these sales.
IMC’s main asset is the Itarantim Project in Bahia and Minas Gerais, Brazil, an ionic adsorbed clay rare earth deposit with an inferred mineral resource of 1.1 billion tonnes grading 1,233 ppm TREO. The company is at the exploration stage, with no operating revenues and a loss of $3.16 million for the year ended March 31, 2026, and reported net liabilities of $7.09 million.
After this resale, IMC expects 115,810,000 ordinary shares to be outstanding. CEO Francesco Scolaro and affiliated entities control about 68% of voting power, making IMC a “controlled company.” IMC is also a foreign private issuer and emerging growth company, using IFRS and eligible for reduced U.S. reporting requirements. The filing highlights significant exploration, financing, technical and jurisdictional risks, including going‑concern uncertainty.
