Highlights
- ANSTO's tests on Ema project samples show higher recoveries than previous studies.
- BCM's project proves competitive globally with low production costs and high-value outputs.
- Field pilot trials for in-situ recovery set to commence, aiming to further enhance project feasibility.
Brazilian Critical Minerals (ASX:BCM) has reported promising results stemming from its partnership with the Australian Nuclear Science and Technology Organisation (ANSTO). Recent tests conducted on samples from the Ema rare earths project revealed greater recovery rates than those documented in the project's previous scoping study.
The scoping study outlined that the project has the potential to produce nearly 100,000 tonnes of rare earths over a 20-year timeline, with some of the lowest operational costs—US$6.15 per kilogram of TREO and US$16.95 per kilogram of NdPr—positioning it as one of the most cost-effective rare earth mining initiatives worldwide.
In an impressive development, tests by ANSTO indicated a significant leap in metallurgical recoveries, hitting 74% for magnet rare earth oxides (MREE) and 62% for total rare earth elements plus yttrium (TREE + Y). This exceeds the previous scoping study's metrics, which were 62% and 48% respectively.
The importance of these results cannot be overstated as they underscore the viability of employing in-situ recovery methods, which are standard practices among major Chinese and Southeast Asian suppliers known for their cost efficiency. The promising test outcomes fuel optimism, as commercial extraction through this method appears feasible.
The ANSTO assessment revealed that the sample contained 829 ppm of TREY, with 30% comprising praseodymium, neodymium, dysprosium, and terbium—key elements with high market value. Recovery rates for these elements were particularly noteworthy, standing at 85% for praseodymium, 72% for neodymium, 70% for terbium, and 63% for dysprosium.
Andrew Reid, Managing Director at BCM, highlighted the team's dedicated efforts over the past six months to maximize rare earth recoveries while keeping impurities to a minimum. He expressed confidence in replicating the laboratory success in real-world conditions as the company gears up for its field pilot trial scheduled to commence in Q2 2025. This pilot will be instrumental in informing the subsequent phases of project development.
By advancing the in-situ recovery technique and achieving superior extraction results, BCM is poised to make significant strides in the rare earths market, enhancing its competitiveness against global players. As the field pilot trial draws nearer, the insights gained are expected to further solidify the project's feasibility and potential profitability.
