### Net Asset Value in Mining | Sell Side Handbook

Asset NAV is the value of the company’s assets, which in mining is its mines. This is calculated by projecting each mine’s after-tax cash flows, discounting it by an appropriate discount rate (5-10% for precious metals), then summing its cash flows to arrive at a present value (AKA NPV or NAV). This is a DCF, but the components of it are ...
