Altona Rare Earths has announced very strong assay results from its newly discovered fluorspar body, at the Monte Muambe project in Mozambique.
Lab assays have confirmed grades ranging from 69.72% to 93.31% CaF₂ across five trench samples, the company said, validating the use of gallium soil geochemistry and highlighting further upside potential.
Altona said the results bolster the case for a 50,000 tonnes-per-annum acid-grade fluorspar operation and will guide drilling and metallurgical programmes in the second half of 2025.
“The discovery and confirmation of new high-grade fluorspar mineralisation further reinforces the strategic value of this unique asset,” chief executive Cédric Simonet said in a statement.
