Pore-size distribution characteristics of Yellowknife mining district rocks, Northwest Territories

Previous studies have indicated a distinct difference between the porosity of similar rock types from Con and Giant mines, Yellowknife mining district, Northwest Territories. As a result, a detailed pore-size distribution study was carried out to determine the reason for the existence of these differences, and to provide information that might be used in interpreting ground and airborne electromagnetic survey data. Results indicate that Giant mine samples generally have higher porosity values which are more evident when comparing similar rock types. High sulphide content is associated with higher porosities in the intermediate pore-size range (10–50 nm) for some samples. Con mine samples have a higher connecting porosity than storage porosity, whereas Giant mine samples have a considerably higher storage porosity than connecting porosity. 2001-E1 S.
