Brazil's antitrust regulator Cade launched an investigation into US rare earth company USAR's proposed acquisition of Brazilian rare earth producer Serra Verde. Serra Verde is currently Brazil's only operational rare earth mine. The transaction includes a 15-year offtake agreement between Serra Verde and a special purpose vehicle funded by US government agencies including the Department of Commerce and the Department of Energy. The agreement explicitly stipulates lowest prices for rare earth elements such as neodymium, praseodymium, dysprosium, and terbium.
