Metallurgical Optimisation Update
Cobra Resources PLC has announced significant metallurgical optimisation results from its Boland in situ recovery project, demonstrating the successful removal of 100% of low-value cerium from the pregnant liquor solution. This process, conducted at ambient temperature and pressure, substantially increases the value of the product by approximately 50%, with the upgraded Mixed Rare Earth Carbonate expected to contain around 38% magnet rare earths and 47% heavy rare earths. High-quality cerium carbonate will be available as a separate by-product, and the company plans to incorporate these findings into its draft Process Flowsheet, with further optimisation studies expected by the end of December 2025.
