ES&E May 1996; Ontario gold mine meets new EA requirements
The Musselwhite Gold Mine has a life expectancy of 15 years. Already 9.7 million tons of mineable reserves have been identified there. Pending approval by the government, the ore will be mined using a combination of open pit and shaft mining. Construction of the mine was scheduled to begin in November 1995.
