Estimating the economics of a mining project on seafloor

This study examines the economic requirements for future commercial mining projects focusing on manganese nodules. Beside the common measures of profitability, the net present value (NPV), and the internal rate of return (IRR), an additional measure, the net profit (NP), is presented to indicate the profitability by considering past and future cost and price trends.
