Dome Mine is situated in the City of Timmins, Ontario, Canada; now known as part of GoldCorp - Porcupine Gold Mines. The original Dome Mine (Tisdale Township) was still operating as of April 2012, its life is slowly coming to an end as the ore is dwindling and quickly becoming exhausted. An enormous discontinued open pit (Super Pit), huge man-made mountain of waste rock and working mill are now in place at the location. At one time a community of approximately 60 houses owned by Dome Mines and leased to miners with families existed.
