Porosity characteristics of mineralized and nonmineralized rocks from the Yellowknife mining district, Northwest Territories

Effective porosity measurements were performed on a suite of 17 samples from the Yellowknife mining district, Northwest Territories. The samples include massive flow, mafic volcanic flow, metagabbro, and talc-chlorite schist. The purpose of this study is to provide basic data to be used in the determination of petrophysical characteristics and electrical conductivity mechanisms of these rocks. The porosity data, when accompanied by other petrophysical measurements, can be used in the development of exploration strategies for aiding interpretation of downhole, ground, and electromagnetic surveys. This paper documents the results and describes the methods and processes used to obtain these porosity data. Results indicate that bulk density ( B) and effective porosity ( E) values are in the ranges of 2.70 to 3.05 g/mL and 0.19 to 2.77%, respectively, for these samples. Massive flow, mafic volcanic flow, talc-chlorite schist, and metagabbro samples have porosity ranges of 0.19 to 0.39%, 0.27 to 2.60%, 0.45 to 0.75%, and 0.67 to 2.77% respectively. 2001-C3 N.
