A magnetometer, IP, CSAMT & Resistivity survey carried out by EGS Indonesia is typically recommended. An anomaly with short spectral Tau, high spectral, low resistivity and a magnetic low could result from fine grained sulphides within an alteration zone. In some environments, this could represent ideal conditions for gold.
In environments where sulphides are more scattered throughout the various gold bearing and non-gold bearing rock types, borehole IP data can more directly correlate detection log results to assays, structure and sulphides percentage to develop a signature that can be applied on a broader scale. EGS Indonesia compiles the geological and geophysics data to get the most information possible. EGS Indonesia has finished many projects in gold exploration.
