U.S. investment fuels purchase of Brazil's rare‑earth miner

The rare‑earth sector has taken centre stage in recent days after the American company USA Rare Earth announced it had completed the capital‑raising arrangement to close the purchase of Serra Verde, the only operating rare‑earth miner in Brazil. The news that propelled the story was the increase in the U.S. government’s contribution to the transaction, which aims to secure a safe and resilient supply chain outside Asia.

Progress in the Serra Verde acquisition

On Monday (the 24th), USA Rare Earth reported that it had secured a total of US$1.5 billion (R$7.7 billion) to finalize the deal, which is expected to close later this week. Of that amount, US$750 million (R$3.8 billion) came from the American government, representing an increase of US$250 million (R$1.2 billion) over the original plan. Michael Blitzer, chief executive officer of USA Rare Earth, said in a statement that the company is proud to continue its partnership with the United States government to build a secure rare‑earth supply chain.

The financing structure for the acquisition also includes a vehicle created specifically to purchase Serra Verde’s production, which will have a total value of US$1.55 billion. In addition to the U.S. government’s contribution, this vehicle will have a bank credit line of up to US$500 million and a commitment from the American government to buy at least US$300 million of rare‑earths over five years. The transaction’s completion depends on a vote by the American company’s shareholders, scheduled for next Friday (the 28th).

The strategic role of the Brazilian miner

Serra Verde operates the Pela Ema mine in Goiás and is identified by USA Rare Earth as the only commercial producer outside Asia capable of supplying the four main magnetic rare‑earth elements: neodymium, praseodymium, dysprosium and terbium. These materials are essential for permanent magnets used in electric vehicles, renewable‑energy equipment and defence systems. The Brazilian miner has already invested more than US$1 billion (R$5.16 billion) in its project, which is considered one of the most advanced in the world.

With the acquisition, USA Rare Earth plans to integrate the Brazilian output into its processing and material‑and‑magnet manufacturing operations in the United States and the United Kingdom. Serra Verde also signed a 15‑year contract to sell 100 % of the first‑phase production of four magnetic rare‑earths to the financial vehicle, with mandatory‑purchase clauses and price floors that reduce the miner’s exposure to market volatility.

Rare earths and global geopolitics

Rare earths are a group of 17 chemically difficult‑to‑extract elements whose geopolitical importance has grown in recent years. Currently, China accounts for more than half of global extraction and controls almost all refining capacity. The American government’s interest in acquiring Serra Verde is part of an effort to lessen that Chinese dependence and secure alternative sources of these critical materials.

Foreign capital in this industry raises questions about national sovereignty as well as economic considerations. In Brazil, the transaction is still under review by Cade (Administrative Council for Economic Defense), which opened a proceeding in May to assess competition concerns. Moreover, the creation of filters and safeguards for foreign investment in the sector is being debated in a bill that establishes a national policy on critical minerals and rare earths, already approved by the Chamber of Deputies and awaiting Senate approval.
