Geology works: The use of regional geological maps in exploration / Геологические работы: Использование региональных геологических карт при проведении геологоразведочных работ

A review of exploration expenditure by exploration stage over 15 years at Laverton Western Australia has identified a poor conversion rate from the first stage (ground acquisition) to the second stage (drill testing). This poor conversion rate is primarily due to poor target selection. The use of a well described ore deposit model and regional geological and regional geophysical datasets is able to improve target selection. The Thermal Aureole Gold ore deposit model and the relevant geological features that can be detected in regional geological maps are described and some examples are shown for Morila, Sadiola and Muruntau gold deposits. <...>
