Operation Bear-Slave, 1971-1974
Operation Bear-Slave is a regional, helicopter-supported, geochemical survey of some 36,000 square miles of the central parts of the Bear and Slave structural provinces of the Canadian Shield. In 1971, a pilot study was carried out in 8 areas to first test geochemical methods. The main field operation was carried out in 1972 when near-shore, inorganic, silty lake sediment and surface lake water sample media were collected at a site density of one per ten square miles.
In 1973, follow-up studies were conducted in the eastern part of the Slave Province. This follow-up work identified base metal anomalies in the drainage systems of the Agricola Lake area, so in 1974 detailed geological, geophysical and geochemical studies were carried out there.
As a follow up to Operation Bear-Slave, lake water samples were collected in the High Lake District and the Takijuq Lake (formerly Takiyauk) area in 1975. Seasonal lake water sampling was carried out in the Agricola Lake area in the same year.
