A Microcomputer Based System For The Prediction Of Mine Profitability

The accurate prediction of mine profitability is essential for success in the present minerals market as is the ability to quantify the influence/of variations in revenues and costs on cash flow. A menu based spreadsheet template has been developed to determine annual cash flow, maintain depreciation schedules, and estimate labor and operating expenses. Sensitivity analyses may be conducted to determine the effect of productivity upon mining costs and the effect of selling price escalation upon rate of return. The advantage of this approach is that it can be used by a wide variety of professionals without extensive computer experience.
