Abstract

Summary

IP, DC Resistivity and MT data have been acquired using three-dimensional arrays at the Green Dam Prospect, located approximately 120 km east-northeast of Kalgoorlie. The 3D acquisition has enabled data interpretation using both two and three-dimensional inversion methods, leading to increased confidence in results and an improved understanding of the variation in mineralization along strike.

The results in the case study will show the IP data clearly map the dominant disseminated Ni- Cu-PGM sulphide mineralization. The data have also mapped the semi-massive to massive Ni-Cu-PGM sulphides and clearly show a high degree of correlation with previously acquired moving loop TEM (MLTEM) and downhole TEM (DHTEM) data.
