geophysical methods to find gold

Geophysical method to explore Primary gold -

2021-5-11  Although these geophysical methods are very crucial for gold exploration, geochemical methods – including portable x-ray florescence (XRF) – remain as the only methods that can measure concentration of gold and other associated elements. Gold is mined as a primary product or as a by-product from a wide range of deposits.

Application of Geophysical Methods to Gold

Finally, the interpretation of surface and underground IP data were used to guide ground prospecting. Through above geophysical work, several possible favorable abnomal locations for concentration of ore-bearing sulfides were distinguished and several locations for gold prospecting were verified by drilling.

Geophysical exploration for gold – A review:

2018-12-6  Geophysical methods have been important in the search for gold in the Witwatersrand Basin of South Africa (magnetic, gravity and even seismic reflection methods), various areas of Canada (e.g. the Abitibi greenstone belt; magnetic, EM and IP surveys), and to a smaller extent in Australia (e.g. Tennants Creek, NT and Water Tank Hill, WA).

Geophysical exploration for gold SpringerLink

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 deposits (Paterson, 1967).
