Australian Rare Earths Defines High-Purity MREO Pathway at Koppamurra

Australian Rare Earths Limited ( (AU:AR3) ) has issued an update.

Australian Rare Earths has reported a key metallurgical breakthrough at its Koppamurra project, confirming a viable, low-risk processing route to produce high-purity Mixed Rare Earth Oxide via an oxalic acid precipitation pathway. Testwork delivered 99.9% rare earth recovery with strong impurity rejection and an initial MREO product projected at 98.6% purity (REO plus yttrium oxide), featuring a magnet-rich assemblage and other strategically constrained elements such as yttrium, gadolinium, samarium and lutetium. The company says this oxalate-based route is simpler and more attractive than mixed rare earth carbonate flowsheets pursued by many western ionic clay projects, improving downstream handling, transport costs and product quality for customers. The work, generated from a three-tonne bulk heap leach campaign, demonstrates a complete, scalable pathway from ore through to saleable intermediates, and ongoing optimisation with ANSTO will feed into the Koppamurra pre-feasibility study, strengthening AR3’s positioning as a potential geopolitically significant, non-Chinese rare earth supply option.

The most recent analyst rating on (AU:AR3) stock is a Hold with a A$0.24 price target. To see the full list of analyst forecasts on Australian Rare Earths Limited stock, see the AU:AR3 Stock Forecast page.
