TMC The Metals Company (NASDAQ: TMC) plans to harvest and process underwater nodules rich in nickel, cobalt, copper, and manganese for battery-grade metals. The company has faced delays awaiting a mining code from the U.N.’s International Seabed Authority but may benefit from new U.S. government initiatives. MP Materials (NYSE: MP) plays a crucial role in the U.S. rare-earth supply chain and processed significant investment from the government and partnerships with private entities. USA Rare Earth (NASDAQ: USAR) aims to establish a domestic supply chain for rare-earth metals and has secured substantial funding for future operations.
