Beschreibung
This textbook is a translation of the German textbook "Rechnen fUr Lagerstattenkundler und Rohstoffwirtschaftler, Teil 1" published by the Ellen Pilger Publishing Company. Those passages in the German edition which were especially written for the German readership were transform ed for English speaking readers. Compared with the German edition many chapters have been slightly amended. The main new additions in this English version are the chapter on linear optimization in Chapter 10.2 and Chapter 12 on the comparison of ore deposits. The textbook is intended for the economic geologist who deals with the evaluation of deposits at an early stage of development. Once an ex ploration project has reached the feasibility stage, the exact calculations of the deposit, the technical and economic assessment will be performed by a team of geologists, mining engineers, metallurgists, and economists. In the early stages of exploration, however, any evaluator of deposits has to be able to cover the whole spectrum himself. Since only order of magnitude parameters are available at this stage, the calculations can only yield order of magnitude results. Precise calculations would even be misleading, since the evaluation does not yet aim at accurate economic assessment but at making the right decision: should the investigation be abandoned or should it be continued at higher costs and with more detailed methods.
Dieses Buch gibt zusammen mit dem Band Statistical Evaluations in Exploration for Mineral Deposits einen umfassenden Überblick über die gängigen Methoden.
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.

From the reviews of the second edition:
"This textbook is designed for economic geologists who deal with the evaluation of deposits at an early stage of development. … the book contains a useful list of references and a number of appendices, including tables, graphs, mathematical formulae, and internet addresses. … is a handy reference for practitioners and a useful textbook for students." (Jean-Michel Rendu, Economic Geology, Vol. 103, 2008)
"The textbook is intended for the economic geologist who deals with the evaluation of deposits at an early stage of development. … 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 … . The case histories, exercises, metal prices and terminology, especially concerning ‘reserves and resources’, have been fully updated in this second edition." (Glückauf, Vol. 145 (6), July, 2009)
