Sommaire: This paper provides a bird's eye view of the pattern of gold discoveries since 1823, the year of Canada's first gold find, up to 1983. Within this 160-year period, more gold was discovered in Canada during the last ten-year period (1973-1982) than during any previous decade. The record suggests that the potential for further major gold discoveries is high, which bodes well for the future of Canadian gold mining.
