The application of soil geochemistry to gold

Soil geochemistry has proved an effective technique in exploration for gold since the 1980s in the Black Flag area, situated some 50 km northwest of Kalgoorlie in Western Australia. Between 1991 and 1995 Mining Corporation of Australia Ltd (“MCA”) conducted a systematic programme of soil geochemistry within a tenement area of some 400 square ...

Geophysical exploration for gold SpringerLink

Abstract. The world-wide interest in gold that has characterized mineral exploration in the 1980s has had a profound effect on the focus and style of geophysical prospecting. In the 1950s and 1960s, direct detection methods (chiefly airborne and ground electromagnetics (EM)) were applied widely in the search for massive sulphide-hosted base-metal ...

In those cases where it will not work, this determination canusually be made at very modest expense. When it does work, it can generate moreuseful data per exploration dollar than any other geophysical technique now beingused in placer exploration.
