Altona Rare Earths Reports High-Grade Fluorspar and Gallium Hits at Monte Muambe

The latest announcement is out from Altona Energy ( (GB:REE) ).

Altona Rare Earths has reported strong initial assay results from its 2025 drilling campaign at the Monte Muambe project in Mozambique, with about 10% of samples processed so far. The company is receiving data from diamond drill holes in both the Fluorite and Python zones, confirming near-surface mineralisation that supports potential open-pit mining.

Significant intercepts show individual grades up to 82.76% CaF2 and 409 g/t Ga2O3, with a weighted average fluorspar grade of 31% CaF2, in line with commercial mining norms and Altona’s expectations. The remaining assays, due in the coming weeks, will underpin a mineral resource estimate for fluorspar and gallium, and management says the results, combined with strong investor interest seen at Mining Indaba, enhance the project’s potential and strategic appeal.

Monte Muambe, already hosting a JORC rare earths resource and backed by a 25-year mining licence, is central to Altona’s strategy to fast-track production of 50,000 tonnes per year of acid-grade fluorspar over at least 12 years while assessing gallium recovery from tailings. The latest drilling results reinforce the project’s role in positioning Altona as a future supplier of critical materials into sectors such as batteries, nuclear fuel and advanced technologies, with implications for investors seeking exposure to Africa’s critical minerals supply chain.

The most recent analyst rating on (GB:REE) stock is a Hold with a £2.50 price target. To see the full list of analyst forecasts on Altona Energy stock, see the GB:REE Stock Forecast page.

Spark’s Take on GB:REE Stock

According to Spark, TipRanks’ AI Analyst, GB:REE is a Neutral.

The score is held down primarily by weak fundamentals: no revenue, sustained losses, continued cash burn, and rising leverage with shrinking equity. Technicals are a meaningful offset, showing a strong uptrend with positive momentum, while valuation remains constrained by negative earnings and no dividend support.
