Ideally suited to the economic geologist who deals with the evaluation of deposits at an early stage of development, this is a highly practical and informative text. It offers rules for quick and easy calculations based on the application of approximate data. It provides both the student and the geologist in the field with a complete set of rules and methods enabling them to perform a quick initial evaluation of the deposit without the support of specialists or computers, even if he is left to his own resources. To support this brilliantly practical approach, all rules for calculations are illustrated with examples, and the mistakes and pitfalls the authors encountered during their careers are pointed out. The case histories, exercises, metal prices and terminology have been fully updated in this second edition. There are new chapters on topics including the lifetime of deposits and the evaluation of mineral prospects without known mineralization.
