Designed to complement traditional engineering texts, this book emphasizes the concepts of mineral project evaluation rather than computation details. It describes various economic evaluation techniques typically employed (including conventional cost analysis, discounted cash flow, and option analysis), their uses, and their relationships with geological, technological, and financial evaluations. Also discussed are the strengths and weaknesses of commonly practiced evaluation methods. This book explains the practical difficulties in conducting an analysis and correctly interpreting the results, as well as the use of alternative techniques. Because many existing texts do not adequately discuss the meanings and application of merit measures, such as net present value (NPV) or internal rate of return (IRR), this book represents an exciting departure from standard reference tools.
