OSLO, Sept 11 (Reuters) - Norway's Petroleum Directorate has identified previously unknown deep sea sulphide mineral deposits, which may include metals such as copper, zinc, cobalt, nickel, vanadium, wolfram and silver, it said on Tuesday.
The minerals were discovered in the western part of the Norwegian Sea at ocean depths of up to 3,500 metres (2.17 miles), the NPD added.
The discovery was made during the NPD's first mineral expedition.
