COLLEAGUES' REVIEWS
"I have gone through the book in great detail and I look forward to seeing it published. I think that it is a very good book, not only for exploration geologists, but also for students and, what I like especially, is that you embrace all scales, the field evidence, the hand specimens, and the microscopic evidence. My review, which is in the status nascendi, will emphasize these advantages... I do hope that the price will be low enough to make it possible for the students to buy it." (G.C. Amstutz, Director, Mineralogisch-Petrographisches Institut, University of Heidelberg, Germany).
"I am impressed with the draft of your book and I compliment you on a fine achievement…. A book that can serve a most useful purpose in the mining industry." (D.A. Pretorius, Director, Economic Geology Research Unit, University of the Witwatersrand, Johannesburg, South Africa).
"Having now seen the book in its entirety, let me say that I regard it as a milestone book. As far as I know, in recent times, no publication has so fully described what is now possible by modern techniques, to see and describe about an ore sample. This is a significant step forward. It should. and will in time, spur metallurgists to develop the science of interpretation of the information into process technology…. A book that metallurgists badly need. " ( Philip M.J. Gray, Consulting Metallurgist and Chairman of the Book Publication Panel of the Institution of Mining and Metallurgy, London, England).

"The areas in which your papers excel - and your book is no exception - are in readability and in the technical details relating to value-bearing minerals. For someone used almost exclusively to lead in galena and zinc in sphalerite, it is a usefull addition to my education. In short, thank you very much for an excellent book." (M.J. Fairweather, Principal Research Metallurgist, Cominco Research, Trail, British Columbia, Canada)
