Resources mined The deep sea contains many different resources available for extraction, including silver, gold, copper, manganese, cobalt, and zinc. These raw materials are found in various forms on the sea floor.

Minerals and related depths[1]

Type of mineral deposit	Average Depth	Resources found Polymetallic nodules	4,000 – 6,000 m	Nickel, copper, cobalt, and manganese Manganese crusts	800 – 2,400 m	Mainly cobalt, some vanadium, molybdenum and platinum Sulfide deposits	1,400 – 3,700 m	Copper, lead and zinc some gold and silver

Sea floor placer deposits

Placer mining (link) for diamonds and gold is also done in shallow sea environments, typically in small scale operations. De Beers for example, mines for diamonds off the coast of Namibia. Nautilus Minerals Inc and Neptune Minerals are planning to mine the offshore waters of Papua New Guinea and New Zealand.[8]
