Gallium is considered a strategic raw material by several jurisdictions including the European Union, with China having a quasi-monopoly on its production. The price of gallium is currently at about US$ 250 per kg, The recent ban of gallium and germanium exports to the United States has propelled gallium to its highest price since 2011, at US$ 585 per kg in December 2024.\n\nThe price shift in gallium, and recent discoveries of high-grade gallium associated to rare earths in carbonatites, has prompted Altona to review its drilling data for this metal. Gallium is one of the trace elements which were analysed by Intertek Laboratories in the course of the preparation of our rare earths mineral resource estimate. Several high-grade gallium intercepts were noted in diamond drilling holes MM039 and MM040, with grades up to 232 g/t Ga.\n\nThe Company is pleased to announce the following significant gallium intercepts:\n\n|   |   |   |\n| --- | --- | --- |\n| Hole ID | From | Length and Grade |\n| MM039 | surface | 100 m @ 77 g/t Ga |\n| including | 70.85m | 14.89m @ 141 g/t Ga |\n| MM040 | 37.3m | 3.14 m @ 87 g/t Ga |\n| MM040 | 57.4m | 25.53m @ 68 g/t Ga |\n| MM040 | 108.2m | 32.27m @ 73 g/t Ga |\n| including | 115.9m | 5.53m @ 134 g/t Ga |\n\nHole MM039 is located at the Northern End of the Fluorite Zone and also contains high-grade rare earths and fluorspar intercepts. It is noteworthy that gallium mineralisation is continuous along the entire length of the hole.\n\nHole MM040 is located on Target 6, which has identified high-grade rare earths mineralisation but has seen relatively little drilling so far in comparison to Target 1 and Target 4.\n\nThis discovery could potentially change the economics of some of the rare earths ore bodies at Monte Muambe, in particular Target 6, by providing an additional valuable by-product. The lateral extension of gallium mineralisation is unknown and will be assessed as part of the next field work campaign.\n\nThe Company will now check the potential recoverability of gallium, starting with establishing the exact mineralogy of gallium mineralisation, which is presently unknown. The Company will also immediately start reviewing the Monte Muambe soil sampling database, which includes first-pass XRF gallium assays, to identify any possible gallium anomalies in soil.\n\n**Fluorspar scoping study progress**\n\nThe Company confirms that the fluorspar samples have been delivered to Peacocke & Simpson laboratory in Zimbabwe for gravity separation and flotation tests, and that the testing process has started. The delay in the delivery was the result of logistical difficulties caused by post-election instability in Mozambique, which has now subsided. Results from this testing are expected during the course of April.\n\n**Cedric Simonet, CEO of Altona, commented: **“Carbonatites systems typically host a wide range of minerals. Monte Muambe is no stranger to this, with the presence of rare earths and fluorspar. The discovery of gallium mineralisation in parts of the carbonatite intrusion that have seen less exploration so far is a positive development for us and underpins the potential for additional discoveries at Monte Muambe.\n\n“While current work on the potential for short-term fluorspar production continues, we will initially carefully assess the possibility of recovering gallium as a by-product of rare earths and/or fluorspar, and the potential extent of gallium mineralisation at surface level.”\n\nThis announcement contains information which, prior to its disclosure, was inside information as stipulated under Regulation 11 of the Market Abuse (Amendment) (EU Exit) Regulations 2019/310 (as amended).\n\nTo subscribe for RNS alerts, please visit: [https://investors.altonare.com/](https://investors.altonare.com/)\n\nAltona Rare Earths Plc\n\nCédric Simonet, CEO                                                                             +44 (0) 7778 866 108\n\nLouise Adrian, CFO                                                                                +44 (0) 7721 492 922\n\n**About Altona Rare Earths Plc**\n\nAltona 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.\n\nThe 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.\n\nThe 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.\n\nAltona 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."}
