This guide to mining valuation will teach you all you need to know to value an asset! The best way to value a mining asset or company is to build a discounted cash flow (DCF) model that takes into account a mining plan produced in a technical report (like a Feasibility Study). Without such a study available, one has to resort to more crude metrics.
