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)
