The Bear-Slave operation was one of the first reconnaissance-style surveys carried out by the Geological Survey of Canada. It covered the central parts of the Bear and Slave Provinces of the Canadian Shield.
A total of 4 102 samples were collected within an area of 94 000 km², with an average density of 1 sample per 26 km².
Reanalysis year was estimated to be 1991, based on publ date being 1992.
