Abstract

A geochemical orientation study in the Davenport Province, Northern Territory, indicates that stream-sediment sampling is an effective geochemical technique for mineral assessment, despite overall poor drainage development. Bismuth, Mo , Sn and W from vein-type deposits appear to be dispersed by mechanical weathering, giving rise to well-defined anomalies in both sieved samples and heavy mineral concentrates. Dispersion trains exceed 10 km downstream from mineralisation, and for regional surveys the analysis of a coarse sieved fraction at a sample spacing of 1 to 2 km is recommended. Dispersion of U and Cu appears to be chemically controlled, and anomalies near known mineralisation in both sieved and heavy mineral samples are either less well defined or absent. Dispersion trains rarely extend more than 1 km from mineralisation , and sample spacing of 0.5 to 1 km, or less, would be necessary.
