ONTARIO – All good things come to an end, including the Dome gold mine in South Porcupine after 107 years and over 67 million oz. Owner Goldcorp of Vancouver said the underground operation will finally wrap up by the end of the year. Aging infrastructure, low productivity and dwindling resources all played a part in the decision.
Dome was one of the earliest mines in the Timmins camp when it opened in 1910. The Dome name has been synonymous with gold almost as long as there has been mining in Ontario. The original underground mine was expanded, deepened, and the mill upgraded for 80 years. In the 1980s, additional mineralization was discovered near the surface, requiring that the mill, offices, manager’s house and other infrastructure be moved to develop an huge open pit. The underground portion of the project was closed for two years (2004-05) but resumed in 2006. The pit has been mined out, however Goldcorp’s Century project is examining the development of another large open pit and mill at the Dome property.
Goldcorp has other properties in Northern Ontario that will keep it a valued employer in the region – the Musselwhite mine, Red Lake mines, and the all-electric Bordon development, plus the Hoyle and Hollinger projects.
