Presents and discusses results of effective porosity, bulk density, & electrical resistivity measurements made on samples from the Giant and Con gold mines, Northwest Territories. The samples represent mineralized and non-mineralized sections of the mines' quartz ankerite veins, sericite schist, chlorite schist, and basalt. The objective of the research is to provide basic data to be used in determining the petrophysical characteristics and electrical conductivity mechanism of these rocks, which would give information required to develop exploration strategies for aiding interpretation of electromagnetic survey data.

Presents & discusses findings of a study to determine whether differences in petrophysical characteristics previously observed between rocks from the Giant and Con mines were associated with the presence of soluble mineral phases in the rocks. The study involved monitoring the resistivity of water used to immerse samples from the two mines (basalt and sericite schist), over a period of 340 hours, after vacuum saturation. The results show the differences between the resistivity-time curves of the water in which the samples were immersed. Suggestions for further studies are presented in the conclusion.

Presents and discusses results of detailed textural examination using scanning electron microscopy on samples from the Giant and Con gold mines, Northwest Territories. The study was a preliminary investigation designed to determine the electrical conductivity mechanisms of the mineralized sericite schist from alteration zones that parallel the gold-bearing quartz veins in the Yellowknife mining district. Results are highlighted for four samples and include schematic representations of rock texture and three-dimensional electrical resistivity. The purpose of the study was to obtain information required to help develop efficient exploration strategies.

Formation resistivity factor and pore-surface resistivity values were determined for three mineralized & nonmineralized rock samples from the Giant mine & Con mine areas of the Yellowknife mining district. The purpose was to provide basic information required to understand the electrical conductivity mechanisms of these rocks and to aid interpretation of geophysical surveys conducted in these areas. This paper describes the methods & processes used to obtain the formation factor data & to document the results for use in future studies.

The purpose of this paper is to document results of electrical resistivity determinations of mineralized sericite schist specimens cut from a single sample collected from the Gold Lake area, Northwest Territories. Resistivity results are presented for frequencies of one hertz to one megahertz and for various orientations within the specimens. The results have application in interpreting ground electromagnetic surveys that are being conducted in the area.
