Altona Rare Earths (LSE: REE) has released new results from its Monte Muambe project in Mozambique, with trench assays returning exceptional fluorspar grades between 69.7% and 93.3% CaF₂, reinforcing the potential for acid‑grade production at scale.
Initial metallurgical testing indicates a high-purity concentrate containing over 93% CaF₂, while iron and other impurities can be reduced to near-commercial levels through flotation, opening the door to a potential 50,00tpa acid-spar operation.
Ground-truthing of gallium soil anomalies also uncovered new high‑grade fluorspar outcrops, suggesting an expanded mineralized footprint with strong upside in resource definition. Altona plans to proceed in the second half of 2025 with advanced metallurgical flowsheet development, offtake sample preparation, and expanded drilling to evaluate fluorspar continuity and potential resource tonnage.
This latest development transforms Monte Muambe into a compelling multi‑commodity critical-minerals asset, anchored by rare earths and gallium, and now enhanced by high-grade fluorspar, positioning the project as a strategic supplier for industrial and battery markets.
