DeepGreen derives base metals from deep-sea nodules

Deep-sea mining hopeful DeepGreen Metals was able to obtain an alloy of base metals by processing polymetallic nodules found on the deep ocean floor

DeepGreen said it would perform confirmatory tests using 100+ tonnes of nodules, in early 2020, to enable design of a commercial plant

The nodules were sourced during a recent expedition to the Clarion-Clipperton Zone (CCZ) of the Pacific Ocean.
