Abstract

Outlet sediment (or overbank) samples from 99 catchments in the Thomson region have been examined by conventional geochemical analytical methods and by partial extraction using Mobile Metal Ion (MMI) leach. Elements such as Pb have good correlation with known mineral deposits using conventional (near-total digestion) methods, whilst elements such as Cu, Au and Ag show a better correlation with known mineral deposits when MMI concentrations are used. This study shows that very low density sampling of catchment outlet sediments (1 site/1540 km2) provides useful and possibly predictive geochemical information for mineral exploration in areas dominated by transported regolith.
