The deep sea mining debate is “gone” — it’s happening, says The Metals Company CEO – by Bruno Venditti ( – April 11, 2023)

Despite opposition from environmental groups, the CEO of The Metals Company (TMC) which has exclusive access to the Nori Clarion-Clipperton Zone (CCZ) polymetallic project, located 4,000 metres deep in the northeastern Pacific Ocean and ranked as the world’s biggest undeveloped nickel project, sees deep sea mining happening by the end of 2024.

Mining international waters is in the spotlight as companies and countries are looking at minerals concentrated on the ocean floor that can be used in batteries for smart phones and electric vehicles.

The Metals Company has said the nodule resource is now estimated at four megatons (Mt) measured, 341Mt indicated and 11Mt inferred mineral resources.

It is estimated that 21 billion tonnes of polymetallic nodules are resting on the ocean floor in the CCZ. Almost 20 international mining companies have contracts to explore the region which spans over 5,000 kilometers and is considered the most prolific area for ocean mining.
