Brazilian Critical Minerals reported results from Phase 2 metallurgical tests on the Ema Project in Brazil, showing up to 83% recovery of magnetic rare earth oxides in 30 minutes, using standard weak ammonium sulphate leaching.

The leachability across the project's 82km2 of rare earth mineralisation indicated the presence of ionic clays, suggesting suitability for conventional processing.

Further metallurgical optimisation and flowsheet development are underway at the Sydney ANSTO facility, with the expected resource estimate by April.
