Lynas Buys Its Way Into Brazil's Clay Belt as BNDES Circles the Refinery

Lynas agrees to acquire Meteoric Resources for about AUD 968 million, gaining Brazil's Caldeira ionic clay deposit in a bid to counter China's heavy rare earths dominance.

Australia's Lynas Rare Earths is betting that the answer to China's chokehold on heavy rare earths lies buried in the red soil of Minas Gerais. The company has struck a binding agreement to absorb Meteoric Resources outright, handing it control of the Caldeira ionic clay project — a deposit type that until now has been a Chinese near-monopoly.

The strategic logic is hard to miss. According to the International Energy Agency, roughly 91 percent of global magnet oxide refining sits in China. Heavy rare earths such as dysprosium and terbium, both essential to the high-performance magnets inside wind turbines and electric drivetrains, have long been treated outside Asia as geologically scarce. Caldeira, by contrast, ranks as the largest known ionic clay occurrence beyond China's borders, with estimated resources of 1.63 billion tonnes of ore.

What the July Study Envisions

A feasibility study completed in July sketches out a 23-year mine life built on 151 million tonnes of ore reserves. Average annual output is pencilled in at 12,500 tonnes of rare earth oxides, a mix that would include 127 tonnes of dysprosium and terbium oxides alongside 3,862 tonnes of neodymium-praseodymium. Should the project come to fruition, it would plug a conspicuous gap in a Lynas portfolio that has leaned heavily toward lighter rare earths.

The price of that strategic insurance is not small. Lynas values the all-scrip transaction at roughly AUD 968 million, offering 0.0207 of its own shares for each Meteoric share — a 68.4 percent premium to the prior close. Once completed, Meteoric's existing holders are expected to own about 5.9 percent of Lynas.

Development spending on Caldeira is put at USD 498 million. To keep things moving, Lynas has already extended Meteoric a credit facility of up to AUD 110 million, with AUD 35 million released as a first tranche.

The Refinery Question

Behind the acquisition sits a larger industrial ambition. Daniel Havas, a Lynas manager, told an investor conference that Brazil's state development bank BNDES has shown pronounced interest in financing a rare earth refinery in Minas Gerais. Mining minister Alexandre Silveira has suggested the facility near Poços de Caldas could grow into one of the world's largest refineries, with support potentially arriving as loans or a minority stake through the bank's BNDESPar arm. Neither the size nor the structure has been settled.

The plan is for a regional processing hub capable of handling not just ore from Caldeira but feedstock from other projects in the area. Before any final decision, Lynas must verify that the various ores are technically compatible.

Malaysia, meanwhile, remains the backbone of the company's separation capacity, which is being expanded to 12,000 tonnes per year. The original blueprint calls for producing mixed rare earth carbonate in Brazil and shipping it to Asia for final separation. No binding investment decision on the Brazilian plant has been made, and the newly created Brazilian council for strategic minerals can attach conditions such as local value-added requirements.

Paper, Not Cash

On the equity market, the combination of dilution and heavy capital commitments has drawn a cautious reception. The stock closed Friday at EUR 8.05, a gain of 2.3 percent. In today's session it added 1.7 percent to trade at EUR 8.00, putting the miner's market capitalisation at EUR 8.54 billion. The muted moves suggest investors recognise that Lynas is willing to absorb near-term margin risk in exchange for long-term leverage over supply.

Paperwork still stands between the deal and completion. Meteoric shareholders are scheduled to vote in January 2027, with closing targeted for March 2027. Australian courts and Brazilian authorities must also sign off, and the national council for critical minerals is expected to scrutinise how much processing value stays in the country. Only after the merger closes is Lynas likely to decide, together with BNDES, whether to break ground on the refinery.

For shareholders, the trade-off is straightforward: less dependence on global supply chains, and considerably more operational execution risk on Lynas's own plate.
