Altona Rare Earths Plc provided an operational update on its Monte Muambe Rare Earths project and on other activities. As previously announced, Prefeasibility Study activities for Monte Muambe are underway and currently focused on advanced metallurgical testing. A 70kg representative ore sample is with Auralia Metallurgy in Perth (Australia), and another 100kg ore sample has been received by SGS Lakefields in Canada.

The sample with SGS Lakefields will first undergo extensive feed characterisation including Electron Microprobe Analysis and TIMA-X analysis. TIMA-X stands for Tescan Integrated Mineral Analyzer and is a one of the newest automated mineralogy technologies. It is designed to provide quantitative mineral speciation and distribution, as well as characterisation, grain size attributes, degree of liberation and associations of minerals of interest.

Following feed characterisation, metallurgical test work will initially focus on producing a high-grade Rare Earth concentrate in order to improve the economics of the Mixed Rare Earth Carbonate production process. The possible separation and recovery of fluorspar, another critical raw material present in the ore at Monte Muambe, will also be assessed. Flotation test results are expected in Second Quarter 2024.

Separation of the 15 Rare Earths present at Monte Muambe from their ore, with a focus on Neodymium, Praseodymium, Terbium and Dysprosium, is a complex process. Metallurgy is a critical component of rare earths projects development. Beside process design and costing, key outputs will also include products specifications to enable discussions with potential off-takers.

Altona attended a very busy Mining Indaba event in Cape Town in early February and was pleased to note the general optimism in the mining industry in Africa, as well as the tangible interest of Western Governments to support the development of critical raw material sources. Altona had fruitful meetings with representatives of several US Government agencies with respect to Monte Muambe. Additionally, the Board of Directors has undertaken a careful and thorough review of the Company's corporate strategy.

As Monte Muambe is advancing, Altona recognises that the time is right for the Company to expand and diversify its portfolio of projects in Africa, including Rare Earths, but also non-Rare Earths critical raw materials such as copper, lithium and niobium. The Company is therefore currently actively assessing potential new opportunities with a focus on projects having a low-entry cost with a clear pathway to early results and to majority ownership.
