Geophysical exploration for gold – A review:

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).

Application of Geophysical Methods to Gold

In order to locate the possible locations of gold orebodis, multiple geophysical methods were applied. Firstly, IP intermediate gradient measurements were carried out in the Houtuan and Banbidian districts, and initial targets were proposed.

Geophysical exploration for epithermal gold

01-02-1990  In applying geophysical methods to epithermal gold exploration, local fac- tors may reduce the effectiveness of a particular technique, or generate an ambiguous data set. Locke and de Ronde (1987) describe the Golden Cross deposit, where overlying volcanic units are strongly magnetic and mask the magnetic low caused by alteration of the underlying host volcanics.

Basic Gold Prospecting Exploration Methods

Prospecting and exploration that is a search for precious metals deposits is not a simple process because big deposits were discovered a long time ago. There are several places with important content of precious metals waiting for skill prospectors. The large mining companies of the world are focused in big deposits and the small deposits are attractive for small miners and perhaps their ...
