allows the extraction of several important geological structures that are believed to play an important role in
determining the morphology of sub-surface gold mineralised zones. In particular the quantification of the degree of
residual enrichment of gold in soils was possible by comparison of the soil results with analyses from drillholes made in
the same area. Based on this relationship, it has been demonstrated that it is possible to use the size and magnitude of
soil gold anomalies to infer the quantity and grade of in-situ gold mineralisation present.
