Serra Verde receives magnet rare earths price floors in US offtake agreement

According to a presentation on the deal, Brazilian rare earth miner Serra Verde will receive price floors for four of the rare earths as part of a 15-year contract with the U.S. government and private investors.

Some critics have suggested that price floors, designed to equalize the playing field between China and other dominant producers of rare earths, could distort the markets.

China produces 90% of the world's rare earths. The U.S. and Europe are also racing to develop their own domestic rare earths industries, which are vital for applications in electronics, defence, and energy transition. As part of an agreement worth billions of dollars, the U.S. offered MP Materials, the company that controls the only rare earth mine in North America a price floor.

Serra Verde announced on Monday that it had signed a 15-year contract to supply the entire first phase output of its plant to a special purpose vehicle, which is capitalised by both private and government sources in the United States.

The deal also includes price floors on the four rare earths that are needed to produce permanent magnets. These include neodymium (the main one), praseodymium (praseodymium), dysprosium (dysprosium) and terbium. They're used in electric cars, wind turbines drones and fighter planes.

The presentation stated that the?floor price of neodymium-praseodymium oxide (NdPr), often sold as a combined product, was the same as the MP Materials' $110 per kilogram. Since the U.S., the Chinese price for NdPr SMM-REO DIO has nearly doubled. The government set a floor price for MP Materials, which was last 795, 000 yuan (or $117/kg) on July 9, 2025 when the MP Materials deal was announced.

Serra Verde is rich in heavy rare Earths unlike other Western deposits. The deal included a floor price for dysprosium (at $575 per kg) and terbium ($2,050 per kg).

It added that the company and U.S. Special Vehicle will share 70 percent of the upside in the event the non-China Market Price rises above floor prices. (Reporting and editing by Paul Simao; Eric Onstad)
