Monitor for results of hydrogeological testing and field-scale pilot testing, which will determine whether laboratory recovery rates translate to commercial viability. The company's ability to secure permits and funding for next-stage field work is critical.

Executive Summary
IMC Rare Earths announced metallurgical test results from the University of Brighton showing 73% in-situ recovery of total rare earth elements (excluding cerium) from its Itarantim Project in Brazil, with 71.4% recovery of terbium and 70.5% of dysprosium. The results support further evaluation of in-situ recovery (ISR) as a potentially lower-capital, lower-impact development pathway, but remain at the laboratory stage with field testing, engineering studies, and permitting still required.
Key Facts
- Laboratory testing recovered 73% of total rare earth elements (excluding cerium) using acidified magnesium sulphate.
- Recovery of high-value magnet rare earths: 71.4% terbium and 70.5% dysprosium.
- Column leaching produced solutions containing 4,000-8,000 mg/L total rare earths.
- Downstream processing produced a mixed rare earth carbonate with up to 86.6% recovery from solution, further processed to a mixed rare earth oxide containing approximately 41% total rare earths.
- Uranium and thorium remained below detection limits in column leachate solutions under tested conditions.
- Itarantim hosts approximately 1.1 billion tonnes of Inferred Mineral Resource containing neodymium, praseodymium, dysprosium, and terbium.
- Next steps include hydrogeological testing, field-scale injection and recovery pilot testing, and continued engineering studies.
Financial Impact
No financial figures reported; results are preliminary metallurgical testwork at laboratory scale. Potential de-risking of ISR pathway could reduce future capital requirements, but no economic assessment provided.
Risk Factors
- Resource is entirely Inferred — no demonstrated economic viability.
- ISR concept unproven at field scale for this deposit; fluid flow and fine clay movement remain key uncertainties.
- No timeline or budget provided for next-stage testing; exploration-stage company with no operating history.
- Permitting, environmental, and community risks in Brazil.
