Century Gold Project

Porcupine Gold Mines, a subsidiary of Goldcorp Canada Ltd., is proposing the construction, operation, decommissioning and abandonment of a new metal mill as well as the expansion of its existing Dome Mine, located in Timmins, Ontario. The area of mine operations for the existing Dome Mine would increase by over 50%. As proposed, the Century Gold Project would operate for 10 to 16 years, and include an open-pit gold mine with an ore production capacity of 70,000 tonnes per day. The on-site metal mill would have an ore input capacity of 70,000 tonnes per day.
