BOOK EXCERPT:

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.

BOOK EXCERPT:

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 EXCERPT:

This paper reports the results of a mapping program in the vicinity of the Boston gold deposit near Hope Bay, south-west Nunavut. It first reviews the regional geology, the granitoid rocks of the Hope Bay volcanic belt, and their contact relationships with the belt. It then focusses on the geology of the deposit area, with descriptions of the rock types, the geologic structures, and the gold mineralization. Finally, implications of the findings for mineralization in other areas of the Hope Bay belt are discussed.
