Lynas Agrees to Acquire Meteoric Resources in $968 Million Brazilian Rare Earths Deal

The International Energy Agency’s 2026 assessment cited in one article says China accounted in 2024 for 60% of mined magnet rare-earth production, 91% of refining and 94% of sintered permanent-magnet manufacturing, highlighting that supply concentration grows further downstream.
Lynas plans to develop Caldeira with Meteoric’s existing team and says the project could eventually support downstream processing in Brazil, in addition to being integrated with Lynas’ operations in Malaysia.
The deal follows USA Rare Earth’s completed US$2.8 billion acquisition of Serra Verde, which the article describes as the only ionic-clay rare-earth mine in commercial production outside Asia.
Lynas chair John Humphrey described Brazil as a supportive mining jurisdiction and said the company would work with Meteoric’s local team, Brazil’s government and local communities to develop Caldeira.
Lynas Rare Earths has agreed to acquire Meteoric Resources for A$968 million in an all-share deal, gaining control of Brazil's Caldeira rare earths project and boosting its resources by 79%. Lynas will give Meteoric shareholders 0.0207 of its own shares for each Meteoric share they own, diluting current Lynas holders but adding high-grade deposits of heavy rare earths like dysprosium and terbium. The deal underscores Western producers' push to reduce reliance on China, which controls 60% of mined magnet rare earth production and 91% of global refining.
The acquisition requires shareholder approval in January 2027 and regulatory clearance in Brazil, with completion expected by March 2027. Stockhead noted that Lynas shares dropped 6% to 8.6% on the announcement, as investors weighed dilution risks against the strategic prize of adding South America's only major rare earths project outside Asia to its growing portfolio.
China's stranglehold on rare earth supply is tightening downstream, not loosening. International Energy Agency data shows China handled 91% of global refining in 2024 and 94% of permanent magnet manufacturing. Western nations are racing to build competing supply chains. Caldeira's ionic-clay deposit holds 802,000 tonnes of neodymium-praseodymium oxides and 41,000 tonnes of heavy rare earths, targeting annual output of 3,862 tonnes of NdPr and 127 tonnes of dysprosium-terbium over 23 years.
John Humphrey, Lynas's chair, said the company is "very pleased with the potential to bring together the Caldeira deposit and Lynas's high-grade Mt Weld deposit." Lynas plans to process mixed rare earth carbonate in Brazil before shipping to its Malaysian separation facility, with potential for downstream refining in Brazil. This diversification strategy positions Lynas as the world's leading non-Chinese rare earths producer.
The all-share structure protects Lynas's A$1.2 billion cash reserve but leaves Meteoric investors vulnerable to Lynas's stock price. Meteoric shareholders receive 0.0207 Lynas shares per share held, valued at A$0.286 at the 60-day average price — a 68.4% premium to Meteoric's prior close. That value immediately eroded when Lynas shares fell 6% to 8.6% on announcement day, demonstrating the fixed-ratio risk. Meteoric shareholders will own just 5.9% of the enlarged company.
Lynas is providing Meteoric up to A$110 million in interim working capital loans to advance the project, starting with A$35 million. Capital costs to build Caldeira are projected to exceed US$500 million. The deal requires 75% shareholder approval from Meteoric voters in January 2027 and regulatory clearance from Brazil's National Council for Critical and Strategic Minerals before March 2027 completion.
Caldeira's resource base expands Lynas's measured and indicated resources by 79% and ore reserves by 26% — a massive addition to the company's portfolio. Yet much of Caldeira's resource remains unmeasured, and projected production figures are targets rather than proven reserves. Canaccord Genuity called the deal a "lower-risk pathway to develop Caldeira," citing Lynas's strong cash flow and balance sheet. Ord Minnett cautioned about potential shareholder dilution and permitting hurdles in Brazil.
The acquisition follows USA Rare Earth's completed US$2.8 billion purchase of Serra Verde, described as the only ionic-clay rare earths mine outside Asia in commercial production. Both deals reflect accelerating competition to secure heavy rare earth supplies for magnets used in electric vehicles and renewable energy. Success hinges on Lynas executing development and securing community support in Brazil, where chair Humphrey pledged to work with Meteoric's local team and regional stakeholders.
