Although aspects of mineral deposit evaluation advantages and disadvantages of each technique are covered in such texts as McKinstry (1948), so that a judgement can be made as to their Peters (1978), Reedman (1979) and Barnes applicability to a particular deposit and the min (1980), no widely available in-depth treatment of ing method proposed or used. Too often, a lack the subject has been presented. It is thus the of this expertise results in the ore-reserve calcula intention of the present book to produce a text tion being undertaken at head-office or, indeed, by the survey department on the mine, and being which is suitable for both undergraduate and treated as a 'number crunching' or geometric postgraduate students of mining geology and exercise divorced from geology. It is essential mining engineering and which, at the same time, that mine ore-reserves are calculated at the mine is of use to those already following a professional by those geologists who are most closely associ career in the mining industry. An attempt has ated with the local geology and who are thus best been made to present the material in such a way able to influence and/or constrain the calculation.

Rezensionen
The author.... writes with evident knowledge of the sometimes difficult professional role of the mine geologist. This is a useful text for a mining geology semester or two, either at senior undergraduate level or as part of a post-graduate professional programme. - Australian Mineral Foundation; This is going to be a very useful book for geologists and other professionals in the mining and mineral extractive industries and a good text for students....everything in this book is relevant.... very well illustrated.... every mine should have a copy. - Mineralogical Magazine; The strength of this book is that it contains numerous interesting facts, explanations of methods and worked-out examples... The reviews of mining methods are comprehensive... this book is very useful in many respects. - Sedimentary Geology; The book is designed to be suitable for both undergraduate and postgraduate students of mining geology and mining engineering, whilst being of use to those already following a career in the mining industry. - IMM Abstracts
