About TMC the metals company Inc.

Overview

We are 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, or the 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 in a single rock.

We believe these four metals
contained in the polymetallic nodules are critical for energy infrastructure and industrial manufacturing. Our resource definition work
to date shows that nodules in our target areas represent the world’s largest estimated undeveloped resource 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 produce three types
of metal products: (i) feedstock
