About Altona Rare Earths Plc

 

Altona Rare Earths Plc (ticker: REE) is a London Main Market-listed
exploration and development company focused on unlocking the value of critical
raw materials across Africa. The Company is pursuing a diversified strategy,
targeting assets with potential for near-term monetisation alongside long-term
growth.

 

The multi-commodity Monte Muambe Project in northwest Mozambique is a highly
prospective tenement hosting rare earths, fluorspar, and gallium
mineralisation. Since acquiring the project in June 2021, Altona has drilled
over 7,800 metres, delivering a maiden JORC Mineral Resource Estimate of
13.6Mt at 2.42% TREO, secured a 25-year mining licence (granted December
2024), and published a Competent Person Report and scoping study for the rare
earths component of the project (October 2023). The Company is actively
seeking a strategic downstream rare earths partner to advance the project
through the prefeasibility stage.

 

In parallel, Altona is progressing plans to fast-track the development of
high-grade fluorspar veins identified along the western and southern margins
of Monte Muambe, with a targeted production of 50,000 tonnes per annum of
acid-grade fluorspar over a minimum 12-year mine life. Acid-grade fluorspar is
a key input in a wide range of applications, including hydrofluoric acid and
lithium battery electrolyte production, placing Altona in a strong position to
supply this critical material.

 

The discovery of gallium mineralisation, with grades up to 550 g/t identified
to date, adds further value to Monte Muambe. The Company is undertaking
mineralogical and metallurgical studies to assess the potential for gallium
production.

 

Altona's diversified portfolio also includes the Sesana Copper-Silver Project
in Botswana, strategically located just 25 km from MMG's Khoemacau Zone 5
copper-silver mine. Situated on a recognised regional contact zone for copper
deposits, Sesana represents a compelling exploration opportunity aligned with
Altona's growth strategy.

 

With a unique combination of critical raw materials projects, Altona is well
positioned to contribute to the global supply of highly sought commodities
essential for clean energy, high technology, defence and industrial
applications.

 

The Company and the Board remain actively focused on identifying and
evaluating additional projects that align with our investment profile and
strategic objectives, leveraging our extensive network and combined industry
experience to uncover compelling opportunities that can drive long-term
growth.
