What TMC the metals Co Inc. does.

We are a deep seabed minerals developer focused on the collection, processing and refining of polymetallic nodules found on the seafloor in international waters of the Clarion Clipperton Zone (“CCZ”), approximately 1,500 miles (or 2,400 kilometers) south-west of San Diego, California. The CCZ is a geological submarine fracture zone of abyssal plains and other formations in the Eastern Pacific Ocean, with a length of around 7,240 kilometers (4,500 miles) that spans approximately 4,500,000 square kilometers (1,737,000 square miles). Polymetallic nodules are discrete rocks that sit unattached to the seafloor, occur in significant quantities in the CCZ and have high concentrations of nickel, copper, cobalt and manganese, alongside meaningful concentrations of rare earth elements (REE) in a single rock.

Our mission is to build a carefully managed, shared stock of metal (a “metal commons”) that can be used, recovered and reused for generations to come. We believe significant quantities of newly mined metal are required because existing metal stocks are insufficient to meet rapidly rising demand.

The four metals and REEs contained in the polymetallic nodules are on the U.S. Department of Interior’s “2025 List of Critical Minerals, with end-uses in strategic sectors including semiconductors and AI data centers, steel manufacturing, the defense and marine industrial base. Nickel was included on the list of 13 minerals selected by the U.S. Department of War in March 2026 for targeted procurement efforts through the Defense Industrial Base Consortium. Our resource definition work to date shows that nodules in our contract areas represent the world’s largest estimated undeveloped resource of several of these critical metals. If we are able to collect polymetallic nodules from the seafloor on a commercial scale, we plan to use such nodules to initially produce nickel-, cobalt- and copper-bearing intermediate and metal cathode products as well as a manganese silicate product of approximately 40% manganese comparable to medium-grade manganese ore. Once in production, we may explore expanding into other product formats including silicomanganese alloy, battery-grade sulfates and precursor Cathode Active Materials (pCAM), as well as extracting REEs contained in nodules.
