| Résumé | (disponible en anglais seulement)
The Saskatchewan Geological Survey initiated a multiyear geoscience project in the Creighton-Flin Flon area, near the Saskatchewan-Manitoba border, as part of
the Government of Saskatchewan's Mineral Development Strategy, a program aimed at supporting diversification of the province's mineral industry. This project, launched in 2018, is focused on understanding the economic potential of the sub-Phanerozoic
basement rocks in the western Flin Flon Domain, and is centred on an area of new airborne geophysical surveys completed in areas between Deschambault, Amisk and Tobin lakes. These surveys comprised helicopter-borne electromagnetic/magnetic surveys
funded as part of the Mineral Development Strategy, and fixed-wing gravity gradiometer surveys funded by Natural Resources Canada. The surveys were designed to help understand the basement geology, in particular, the distribution of volcanic
sequences that might host volcanogenic massive sulfide deposits and the expressions of ore-forming systems to depth, as well as to provide guidance for exploration. The locations of the airborne surveys were selected to cover areas lacking
geophysical data or to provide higher-quality data for areas covered by previous surveys. In this first year of the project, three surveys were conducted using CGG's (Compagnie Générale de Géophysique) HeliTEM EM/magnetic system, and two surveys were
conducted using CGG's Falcon gravity gradiometer system. Each survey used a line spacing of 200 m with 1200 m tie-lines. In order to provide value-added products to the new surveys, physical rock properties, including specific gravity, magnetic
susceptibility and conductivity, were measured during the summer of 2018 on core samples from drillholes collared in the survey areas. In total, core from 18 boreholes was examined and more than 3000 measurements were collected, to better understand
the link between geological and geophysical features in the area. Conductivity measurements clearly defined sulfide mineralization zones in drillcore. Specific gravity and magnetic susceptibility measurements could not only indicate the mineralized
zones, but could also differentiate between some lithological units, based on their physical characteristics. |
