The Timmins-Porcupine gold camp, with a total production of more than 2,125 tonnes (75 Moz) Au to date, represents the largest Archean orogenic greenstone-hosted gold camp worldwide in terms of total gold production. The gold deposits of the camp are distributed over 50 km of strike length along the Destor-Porcupine fault zone, including the giant Hollinger-McIntyre and Dome deposits.
