One of many factors determining the success of the future exploitation of oceanic polymetallic nodules is the amount of resources and the accuracy of their estimation. The potential exploitation requires accurate estimation of resources classified as measured resources according to the Australian JORC Code (The Joint Ore Reserves Committee Code). The issue of the accuracy of polymetallic nodule resources estimation was analyzed in the area of the Clarion-Clipperton Fracture Zone in the Pacific administered by the ...

The paper is aimed at estimating the abundance of polymetallic nodules in the Pacific area is administered by the Interoceanmetal Joint Organization (IOM) using statistical and geostatistical methods. Polymetallic nodules occurring in the Clarion-Clipperton zone in the Eastern Pacific Ocean contain numerous metals, of which the most important are Co, Cu, Ni, and Mn. In the area administered by the IOM, the four genotypes of nodules are marked with the following symbols: D and D1 (diagenetic), H (hydrogenic), and H...
