Page 11 - Handbook of Gold Exploration and Evaluation

x Foreword

surface studies involve similar geochemical stream and soil sediment surveys.
Similar geological and geophysical techniques also apply to sub-surface investi-
gations in both primary and secondary gold settings including geomorphic
reconstructions of palaeo-erosional surfaces. Remote sensing techniques employ
similar sensors to map relevant geological and geomorphic features and dating
of the same key rock types and minerals helps clarify the geological history of
any area under investigation in both ancient and modern tectonic settings.
Future demands on gold will be very great and additions to resource
quantities of both primary and secondary gold ores must increase in order to
cope with increasing demand. Definition of that part of a resource that might be
mined economically within the guidelines laid down for exploration is an
essential requirement of economic evaluation.
This book will be of special interest and use to exploration and mining
geologists, mining engineers, metallurgists, academics and students alike. How-
ever, the book is written in such a manner that non-technical people will find it
informative and it will help them gain a thorough understanding of gold
exploration.
Finally, congratulations Eoin on the tremendous achievement of publishing
Handbook of Gold Exploration and Valuation in your 90th year, and may the
ultimate compliment to you be the discovery and successful exploitation of a
new alluvial gold deposit.
