Book Description
The purpose of this paper is to document results of the electrical resistivity characteristics of rocks from the Astarte River Formation, central Baffin Island, for use in interpreting ground electromagnetic surveys that have been conducted in the central Baffin region. Results are presented for five black graphitic shale samples subjected to three-dimensional electrical resistivity measurements & subsequent data analysis. The samples were selected to characterize the resistivity of the Formation and to determine the effect of strong foliation containing porous layers & of disseminated sulphide mineralization oriented parallel to foliation.

Book Description
This paper describes a novel, high-resolution application of cross-borehole seismology at the Snap Lake diamond mine, Northwest Territories, to assess whether the relatively thin kimberlite dyke that hosts the diamonds could be mapped underground with sufficient resolution to accurately estimate its volume and to guide mining. Subsequent mining and mapping with the 50-by-70-metre test panel indicated whether the technique was able to map the top & bottom surfaces of the dyke and to identify ramps, pinch-outs, and cross-cutting fracture planes. The tests also compared the performance of that new technique with two other geophysical methods, high-frequency vibrating seismic surveying and ground penetrating radar.

Book Description
The purpose of this paper is to document results of the determination of electrical resistivity characteristics of schist samples from the Gold Lake area of the Yellowknife mining district, Northwest Territories, for use in interpreting ground electromagnetic surveys that have been conducted in that region. Results are presented from investigations of electrical conductivity mechanisms determined for five sub-samples taken from two mineralized schist samples selected to characterize the resistivity of the alteration zone and to determine the effect of cross-cutting veins & of fine-grained sulphide minerals oriented parallel to foliation. Resistivity-related factors examined in the study include sulphide grain connectivity, the insulating quality of quartz & calcite grain layers, and pore-fluid connectivity.

Book Description
Describes studies conducted as part of a program to provide baseline data of surficial materials, ice-flow history, and soil geochemistry in the Yellowknife area, aimed at augmenting the geoscience database to support mineral exploration & development. After description of the regional setting & bedrock geology of the area, information is presented on surficial sediments (till, glaciofluvial & glaciolacustrine sediments, peat), ice flow patterns, glacial history, and pebble lithology provenance.
