Mining Economics and Finance is the applied discipline that brings economic and financial analysis principles to bear on the evaluation, funding, and management of mineral projects and operations. It encompasses capital and operating cost estimation, revenue forecasting based on production volumes and commodity price assumptions, discounted cash flow analysis to derive metrics such as net present value and internal rate of return, payback period calculation, and sensitivity and scenario analysis to test project resilience against variables such as price volatility, exchange rates, and cost inflation. It also covers the structuring of mining finance, which can include traditional equity and debt financing, project finance arrangements, streaming and royalty agreements, offtake-linked financing, and government or multilateral development bank involvement. Mining economics must account for industry-specific characteristics including high capital intensity, long lead times from discovery to production, significant commodity price cyclicality, and elevated geological and political risk relative to many other industries. These considerations apply across all four commodities discussed here, though their relative weighting differs; gold projects are often highly sensitive to gold price assumptions and exchange rate movements, while bulk commodities like iron ore and bauxite are heavily influenced by freight costs and infrastructure capital intensity, and diamond projects carry additional complexity due to the heterogeneous nature of diamond valuation.
