Lynas Buys Brazil's Largest Rare Earth Deposit Outside China in $672 Million All-Share Deal

Lynas Rare Earths announced on October 1, 2026 that it has signed a binding agreement to acquire Meteoric Resources and its Caldeira rare earth project in Minas Gerais, Brazil, in an all-share deal valued at approximately A$968 million, or roughly US$670 to US$678 million depending on the exchange-rate snapshot used, according to Tech Times, Mining.com, Investing News Network and BN Americas.

Lynas is the only company outside China that commercially separates dysprosium and terbium, the heavy rare earth elements used in the permanent magnets that power high-performance electric vehicle motors and military hardware, according to Tech Times. China has controlled roughly 90 percent of global rare earth processing and tightened export restrictions on the sector in April 2025 under MOFCOM Announcement No. 18, Tech Times reported. That context is why a Brazilian clay deposit is suddenly worth nearly a billion Australian dollars in stock.

What Lynas Is Actually Buying

Caldeira is described by Investing News Network as the largest known ionic clay rare earth mineral resource outside China under the JORC reporting code. Across measured, indicated and inferred categories, the deposit holds an estimated 802,000 tonnes of neodymium-praseodymium oxide and 41,000 tonnes of dysprosium-terbium oxide, Investing News reported. A completed definitive feasibility study projects average annual production of about 3,862 tonnes of NdPr oxides and 127 tonnes of DyTb oxides over the mine's life.

Lynas says the acquisition will lift its measured and indicated total rare earth oxide resources by about 79 percent and its ore reserves by roughly 26 percent on a pro forma basis, according to Investing News.

Deal Terms

Under the Scheme Implementation Deed, Meteoric shareholders will receive 0.0207 Lynas shares for every Meteoric share they hold, implying a value of about A$0.286 per Meteoric share, a 68.4 percent premium over Meteoric's last close of A$0.170, according to Tech Times and marketindex.com.au. Once the scheme completes, Meteoric shareholders will hold about 5.9 percent of the combined company.

The Meteoric board unanimously recommended the deal, subject to an independent expert confirming it serves shareholders' best interests and no better offer emerging, Tech Times reported. Major shareholder Tolga Kumova, who controls about 6.7 percent of Meteoric's shares, has also pledged support subject to the same conditions.

The scheme needs approval from 75 percent of votes cast plus court sign-off. According to marketindex.com.au, the shareholder vote is expected in late January 2027, with implementation targeted for early March 2027. To keep Caldeira moving in the meantime, Lynas is providing an interim funding facility of up to A$110 million, with an initial A$35 million available immediately for environmental licensing and ongoing development, Tech Times reported.

Why the Stock Fell

Lynas shares dropped as much as 7.8 percent to A$12.75 in early trading, marketindex.com.au reported, while Epoch Times put the midday decline at 5.5 percent to A$13.065. Meteoric shares, on the other side of the trade, soared as much as 50 percent to a near two-year high of 25.5 cents, according to Epoch Times.

The skepticism warrants serious attention. Marketindex.com.au's reporting lays out the concern plainly: the deal is all-scrip, meaning Lynas is handing over equity rather than cash, and it still needs to spend heavily, over US$500 million by Lynas's own estimate reported by Mining.com, to actually build a mine in a country where it has never operated. That is a real execution risk, not a hypothetical one. Lynas has roughly $1.2 billion in cash and short-term deposits on hand, according to Epoch Times, so it isn't stretched for capital, but turning an ionic clay deposit in Minas Gerais into producing tonnage by a 2028 target is a different proposition than signing a term sheet.

Lynas Chairman John Humphrey pushed back on that framing in comments to analysts on October 1, pointing to the company's record at its Kalgoorlie processing facility, which marketindex.com.au reports went from construction to production in two and a half years. "Caldeira is the right asset for Lynas at the right time, squarely consistent with our Towards 2030 strategy," Humphrey said, according to Epoch Times. Meteoric Executive Chair Andrew Tunks said the project is "high grade, highly recoverable, low in capital intensity, low in operating cost, and highly scalable," per Investing News Network.

The Bigger Picture

Lynas, whose largest shareholder is Gina Rinehart's Hancock Prospecting with an 8.2 percent stake worth about $1 billion according to Epoch Times, is already the dominant Western alternative to Chinese rare earth processing through its Mt Weld mine in Australia and its separation plant in Malaysia. Adding a Brazilian feedstock source diversifies where its raw material comes from, which matters given how exposed the entire Western supply chain is to a single country's export policy.

The open question is execution, not strategy. Lynas will need shareholder approval, court sign-off, an independent expert's blessing, and then several years of construction before Caldeira ships a single tonne of oxide. Investors who sold Lynas stock on October 1 are betting the risk of getting there outweighs the strategic logic of getting away from China. The scheme vote in late January 2027 will be the first real test of whether shareholders agree.
