Structural Economic Assessment of Polymetallic Nodules Mining Project with Updates to Present Market Conditions

This paper presents the economic structure, assumptions, and relations of deep-sea mining project assessment results its evaluation, based on exploration activities research in field geology, technology, processing environmental legislative studies. The Interoceanmetal Joint Organization (IOM) cooperating organizations conducted a study incorporating those elements that are recognized as most important for commercial viability. On basis formulated financial flow operating capital expenses one technology possible market unit price polymetallic nodules was estimated result is presented this paper. rapidly changing situation, affected inter alia by COVID-19 pandemic, reflected updated recent changes metal prices. Although assumptions related to costs need be confirmed during pilot tests, promising have been shown case use high-pressure acid leaching (HPAL) well raw ore sales. A pre-feasibility will focus two variants model.
