Barkly Rare Earths Hits 99% Magnet Rare Earth Extraction in Early Metallurgical Test

Highlights

• Barkly Rare Earths achieved 99% MREO extraction into solution from a single caustic-conversion and hydrochloric-acid leach test at its Northern Territory project.
• 92% of phosphorus was separated into a caustic stream with no measurable rare earth losses, potentially simplifying downstream purification.
• The calculated head reconciled to only 87% of the directly assayed MREO head, flagged as a small-test limitation by the company.
• The 40 Mt resource at 2,100 ppm TREO carries a strong 34% MREO/TREO ratio, but repeatability, impurity removal, and project economics are still undemonstrated.
