From introduction: While much has been written concerning nodule resources, conceptual mine-process systems, and economics, no published work is available which addresses the question of profitability of mining a specific nodule deposit. Therefore, the purposes of this report are to analyze available information on deposits in the northeast Pacific high-grade zone in an attempt to identify areas of high grade and abundance, and determine their minability and profitability based on existing technology and economics. A final purpose, irrespective of profitability, is to analyze the potential beneficial impacts nodule production could have on the U.S. supply of nickel, copper, cobalt, and manganese.
