TMC the metals company Inc., doing business as The Metals Company, formerly DeepGreen Metals, is a Canadian deep sea mining exploration company. The company focuses on the mining of polymetallic nodules in the Clarion Clipperton Zone of the Pacific. In 2021, DeepGreen Metals was acquired by Sustainable Opportunities Acquisition Corp in a $2.9 billion special-purpose acquisition company deal. TMC is now listed on the Nasdaq Stock Exchange. Baird Maritime noted that The Metals Company had no revenue or production as of April 2021, and highlighted the company's risky commercialization efforts: "Nobody has successfully managed to commercially harvest the nickel, copper, manganese, and cobalt from the nodules in 4,500 metres of water since interest was first stimulated in seabed mining in the 1970s."
