An Introduction to Cut-off Grade Estimation examines one of the most important calculations in the mining industry. Cut-off grades are essential to determining the economic feasibility and mine life of a project. Profitability and socioeconomic impact of mining operations are influenced by the choice of cut-off grades. Cut-off grades play a key role in estimating mineral reserves that can be publicly reported.

This new edition is easier to read and of greater practical interest to practitioners. The relationship between optimization of net present value, capacity constraints, and opportunity cost is explained in greater detail. A new section discusses blending strategies, which play a critical role in an increasing number of mining operations.

Author Jean-Michel Rendu, an internationally recognized expert in the management, estimation, and public reporting of mineral resources, provides practical insights. As a manager in major mining companies, a consultant, and an educator, Rendu has acquired considerable experience in all aspects of mining engineering, experience that was incorporated into this publication.

This is a must-read for mine managers, analysts, geologists, mining engineers, and public policymakers who want to stay on the leading edge of their profession.

Mining is not for the fainthearted. Yes, the rewards are enormous. But so are the risks—and consequences—of failure. Risk Management in Evaluating Mineral Deposits walks you through the many-faceted risk evaluation you need to conduct before you invest your hard-earned dollars. Written by a mining professional with a strong background in technical and financial studies, risk assessment, and statistics, this book provides a detailed suite of tools so you can determine whether investing in a mining project makes sense for you. Looking at a host of issues—the composition of the ore deposit, the management’s previous record, the quality of the information at hand, and your own risk-tolerance comfortlevel, to name a few—author Jean-Michel Rendu provides a comprehensive guide to determine when to invest with high confi dence, when to demand a plan that reduces the risks and increases the chances of a positive outcome, and when to just walk away. This book will have relevance for many years. Unlike others, Rendu factors in not just fi nancial but environmental and social aspects to evaluate the triple bottom line. He shows you why your project needs a different evaluator for each of these three legs and how to combine their evaluations to make one decision. As more and more government agencies and communities insist on these types of metrics, this focus will help keep you up-to-date in a rapidly changing world and increase the possibility that your investment will generate profi ts even in this complex, uncertain, and timeconstrained industry.
