Exploration Geochemical Applications
1. As a Pathfinder

Indicator of Cu mineralization of any type; also important pathfinder for many types of gold deposit. Although further investigation is always justified, elevated Cu values are, however, more likely to indicate the presence of mafic rocks.

In the search for ultramafic-hosted magmatic nickel deposits, elevated Cu values may enable the discrimination of Ni anomalies associated with sulphide from those derived from unmineralized ultramafic rocks.

2. As an Aid to Geological Mapping

Indicative of mafic rocks, though Cr and Ni are less ambiguous indicators
