Seabed mining environmental study underway

An environmental study on seabed mining for “polymetallic nodules” - rocks that contain metals needed to build batteries, is underway in the Clarion Clipperton Zone (CCZ) of the Pacific between Hawaii and Mexico. The aim is to use the metals to power electric cars. The study is being undertaken by DeepGreen Metals Inc., a Canadian-based seafloor mining developer, which acquired Tonga Offshore Mining Limited (TOML) last year, and has sponsorship from the Tonga government for seabed exploration.
