Deep-Sea Mining is Inevitable
Deep-sea mining resources are typically rich in Cobalt, with grades of 0.2% (CCZ) to 0.4% (Cook Islands and Minamitorishima). Given the relatively low cost of production and large volumes produced, it is likely that deep-sea mining production of Cobalt will displace many artisinal and high-cost producers of Cobalt.
