The Con Mine was a large goldmine located in the Northwest Territories, at Yellowknife. The property was staked by Cominco in September 1935 in response to the discovery of visible gold nearby. The advent of winter prevented any prospecting from being conducted, but work in the summer of 1936 led to the discovery of numerous gold veins. Con Mine entered production in 1938 and ceased operations in 2003. It has produced over 5 million ounces of gold.
