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)
