By the end of its production, the Wright-Hargreaves would be the deepest mine in the Kirkland Lake camp with workings at the 8200 foot level.[3] The mine was in regular production between 1921 and 1964. Production ceased following a serious rock burst underground in August 1964. The processing plant was previously shutdown in 1957 and production was transported to the Lake Shore mine for processing. Final salvage activities and clean up were completed in 1965, with a total production of 4,821,296 ounces of gold at an average grade of 0.49 ounces per ton.[4] See also
