The electrical conductivity mechanisms have been determined for six mineralized sericite schist specimens cut from a large sample collected from the Gold Lake area of the Yellowknife mining district, Northwest Territories. This work consists of analysis and interpretation of 3-D electrical resistivity measurements. The sample was selected to characterize the resistivity of the alteration zone and determine the effect of crosscutting veins and the sections of fine-grained sulphides oriented

The purpose of this paper is to document results of the electrical resistivity determinations obtained to assist interpretation of electromagnetic surveys currently being conducted in the area. The bulk electrical resistivities (ρ r ) of the six specimens investigated in this study are in the range of 5.9-140 Ω·m with anisotropy values ranging from 3:1 to 7:1. The arsenopyrite-filled fractures showed the lowest ρ r values (5.9-17 Ω·m).
