Copper, Cobalt, Nickel and Manganese Availability from Land‐based Endowments A Perspective

Natural Resources Forum, 1984, vol. 8, issue 3, 267-278

Abstract: Estimates of land‐based demonstrated resources of cobalt, copper, manganese, and nickel would indicate adequate supply for many years to come based on current levels of annual consumption. However, when these resource estimates are disaggregated, much of this resource is found to occur in a limited number of producing mines. Almost all of the cobalt in these resources coexists with either nickel or copper, and as such, will be available only to the degree extraction of these two metals from existing mines is economical. Finally, current projections of excess capacity in existing mines for all four metals, coupled with additional inferred resources at these mines and yet to be exploited resources in known economical deposits, would lead one to conclude that, from this perspective, the mining of sea bed nodules is not likely to occur until well into the next century.
