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 minยญ (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 calculaยญ 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 associยญ 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
