MTM Critical Metals Limited (“MTM” or the “Company”) (ASX: MTM; OTCQB: MTMCF) is excited to announce a major breakthrough in its innovative Flash Joule Heating (FJH) technology, achieving enhanced efficiencies in rare earth element (REE) processing beyond previously reported results2 including for the highly valuable ‘magnet REEs, Nd, Pr, Dy, Tb. This achievement marks a significant milestone for MTM, further reinforcing the potential to revolutionise and improve the economics and sustainability of traditional REE processing methods.

• Enhanced REE Conversion Efficiency: Achieved 93% (average) conversion of Rare Earth Elements (REEs) to chlorides, a major improvement over prior results through refined carbo-chlorination parameters.
• Very high Impurity Removal: ~95% reduction in key impurities (Fe, Al, P) from REE concentrate in a simple single-step FJH process, revolutionising traditional REE processing.
• Streamlined Process Flow: Strengthened the technology’s potential to replace traditional complex sulphuric acid roasting & purification workflows with a compact, single-step solution.
• High-Purity REE-Chloride Production: Achieved >90% purity product, significantly reducing complexity, downstream purification needs, and reagent use compared to traditional sulphuric acid roasting methods.
• Challenges with Current Methods: Incumbent REE extraction methods rely on energy-intensive acid baking and water-heavy processes, generating significant waste and environmental impact1.
• Path to Commercialisation: Active discussions with industry stakeholders to explore adoption and integration of this transformative technology into rare earth supply chains.
• Strategic Alignment: aligns with U.S. initiatives to re-shore critical mineral refining, reduce foreign reliance, and strengthen domestic REE supply chains, supported by upcoming US administration changes.
