Monte Muambe: Strong Initial Assay Results
Altona Rare Earths PLC has announced strong initial assay results from its 2025 drilling campaign at Monte Muambe, with individual grades reaching up to 82.76% CaF2 and 409 g/t Ga2O3, and a weighted average grade of significant intercepts at 31% CaF2, consistent with industry expectations. These results, representing approximately 10% of the samples, indicate suitability for open-pit mining and are expected to contribute to the project's fluorspar and gallium Mineral Resource Estimate. The company also noted significant strategic and financial interest in its projects at a recent mining conference. Disclaimer*
