USA Rare Earth Acquires Serra Verde for $2.8B, Expands Heavy Rare Earth Mining Outside Asia

Published: Sep 11, 2026 11:57 (GMT+8)

【SMM Rare Earth Flash】 U.S. rare earth producer USA Rare Earth (USAR) has completed its US$2.8 billion acquisition of Brazilian producer Serra Verde, adding one of the few operating heavy rare earth mines outside Asia to its growing mine-to-magnet business. Serra Verde's Pela Ema ionic clay operation in Brazil is expanding toward a target capacity of 6,400 t/y of rare earth oxides, providing USAR with direct dysprosium and terbium supply.

The deal is the latest step in USAR's effort to build a fully integrated rare earth supply chain spanning mining, separation, metals, and magnets. The company fully consolidated the Round Top project in Texas in March and acquired UK-based metals and alloys producer Less Common Metals last September. The transaction is backed by government support: Serra Verde's production is covered by a 15-year offtake agreement, and USAR has secured up to US$1.6 billion in funding from the U.S. Department of Commerce. Former Serra Verde CEO Thras Moraitis has joined USAR's board and will assume the CEO role on October 1.

Overseas rare earth prices remained largely stable this week, with mediocre trading. The EU adjusted its sanctions list against Russia, giving a green light to Estonia's rare earth processing needs. Aclara expanded its separation scope and commissioned a metallization demonstration plant, Lynas acquired the Caldeira project in Brazil, and LS Group advanced the South Korea-Vietnam ex-China magnet supply chain. In rare earth-free magnets, Niron secured a $150 million loan from the US Department of Defense and investment from Honda, while Moog will jointly showcase related solutions. Indonesia and the US discussed cooperation in rare earths and other areas.
