About Altona Rare Earths Plc

Altona is a resource exploration and development company focused on critical raw materials in Africa. The Company is listed on the Main Market of the London Stock Exchange with the ticker "REE". The Company currently holds copper, fluorspar and rare earths projects.

The Monte Muambe rare earths and fluorspar projects is located in Northwest Mozambique. The Project was acquired in June 2021, and the Company has so far drilled over 7,800m, and defined a maiden JORC Mineral Resource Estimate of 13.6 million tons at 2.42% TREO. A Competent Person Report including the Scoping Study for Monte Muambe was published on 18 October 2023. The Project is now at Prefeasibility Study stage, with a focus on metallurgical testing for rare earths extraction.

The Company is also assessing the possibility of rapidly putting in production high-grade fluorspar veins occurring at Monte Muambe along the western margin of the rare earth bearing carbonatite intrusion.

Altona is presently diversifying its portfolio by acquiring a limited number of critical raw material projects to complement Monte Muambe. The acquisitions of the Kabompo South copper project in Zambia and of the Sesana copper-silver project in Botswana, located just 25 km from MMG's Khoemacau Zone 5 copper-silver mine, represent the first steps towards the implementation of this expanded strategy.
