TMC vs GVA Comparison

TMC The Metals Co Inc is a deep-sea minerals exploration company focused on the collection, processing, and refining of polymetallic nodules found on the seafloor in international waters of the Clarion Clipperton Zone (CCZ). Polymetallic nodules are discrete rocks that sit unattached to the seafloor, occur in notable quantities in the CCZ, and have high concentrations of nickel, copper, cobalt, and manganese in a single rock. The company believes these four metals contained in the polymetallic nodules are critical for energy infrastructure and industrial manufacturing. The Company's business consists of only one operating segment, namely exploration of seafloor polymetallic nodules, which includes the development of a metallurgical process to treat such seafloor polymetallic nodules.
