Geophysical method to explore Primary gold Geology

Although these geophysical methods are very crucial for gold exploration, geochemical methods – including portable xray florescenceXRF – 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 byproduct from a wide range of deposits.

Basic Gold Prospecting Exploration Methods

In turn, this is followed by detailed geophysical studies and later, a detailed drilling, sampling, assaying and mineralogical study. Gold deposits are sought with many techniques, but they are based on geochemical studies. Commonly more than one method is employed. With these methods, the geologist is looking for anomalies.
