Miner secures 'more' rare earth deposits

By Kingsley Jassi: Australia Stock Exchange-listed miner Chilwa Minerals says it has discovered widespread rare earth minerals at its site, Lake Chilwa, in the Southern Region. This reported discovery directly beneath Mposa heavy minerals sands deposit, continues to position Malawi as a globally significant rare earth source. In a statement, Chilwa Minerals Managing Director Cadell Buss says they are elated with the development. "We set out to test whether the clays beneath our Mposa mineral sands deposit carried rare earths, and the assays have come back confirming widespread rare earth elements mineralisation," Buss says. He says the basket is encouraging too, with the valuable magnet rare earths—neodymium, praseodymium, dysprosium and terbium—making up about a fifth of the total. According to the statement, the real prize would be if these rare earths prove to be held in an ionic-adsorption clay form, the style behind some of the world's lowest-cost rare earth operations. The rare earth industry is dominated by China, which claims over 80 percent of the total global market share although more discoveries in some parts of Africa and the United States pose a challenge to this dominance. According to an analysis by Transparency Market Research website, the global rare earth metals market size was valued at $14.1 billion in 2025 and is projected to reach $30.9 billion by 2036. "The market is expected to be driven by accelerating demand from electric vehicles and clean energy technologies," the website indicates. About the new discovery, Chilwa Minerals states that a heavy magnet rare earth proportion of this order is characteristic of clay-hosted deposits and is significant as these elements carry the majority of rare earth basket value. However, no metallurgical work has been carried out so far and, as such, the proportion of the contained rare earths present in a recoverable and ionic-absorbed form is unknown. The new discovery comes at the time the first-ever rare earth mine conducted a maiden blast in Balaka District, at Kangankunde Rare Earth Mine by Lindian Resources, another Australian company. The site has at least 261 million tonnes of rare earth deposits with a 45-year mine life during which at least $114 million of annual revenue would be generated. Malawi now has at least four rare earth sites that also include Kasiya in Lilongwe, where the same deposits also contain rutile and graphite. The other is Songwe Hill in Phalombe District, where Mkango Resources is advancing mine development activities.
