The open-pit Detour Lake operation is the largest gold producing mine in Canada with the country's largest gold mineral reserves.

Located within the northernmost Abitibi Greenstone Belt, the mine was originally owned and operated by Placer Dome primarily as an underground mine from 1987 to 1999. Production resumed in 2013 as an open-pit mine under the ownership of Detour Gold Corporation. 

Agnico Eagle acquired its interest in the Detour Lake mine on February 8, 2022. Ore is processed using a conventional crushing, grinding, gravity, cyanidation and carbon-in-pulp processing facility to recover gold.
