The deep seabed polymetallic nodules are one the major types of deep-sea ore resources. Oceanic deposits of these raw materials represent a potential source of numerous metals that are in short supply on the land-base deposits at the nearest future. The process of geological survey to the deep ocean floor is considered to be an onset of a quantitatively new stage in the process of mineral resource extraction. Continuation of the on-going work on polymetallic nodule deposits within the Clarion-Clipperton Zone is regarded as a serious task to be undertaken over a period until the year 2025, with a due consideration to advance in designing of an efficient mining unit and application of modern processing technologies for extraction of major metals : manganese, nickel, cobalt and copper. A prerequisite of a rational management of oceanic resources is the preservation of natural oceanic environment. Considered is the extraction's profitability of a concrete deposit within the Clarion-Clipperton Zone, which is the exploration area of the IOM, with annual production scale of 2.2 Mt of wet nodules for the year 2025.
