Sudbury remains one of the world’s foremost nickel and copper mining camps with continuous production since 1886. Inco and Falconbridge Mining Companies have been mining nickel-copper ores in the Sudbury area of northern Ontario since 1902 and 1929, respectively. Today, Incosrc="/NRs Sudbury operations consist of six underground mines, one mill, one smelter and one refinery, employing approximately 6,400 people. Falconbridge operations consist of three underground mines, a mill and a smelter, employing approximately 1,500 people. These facilities are spread throughout the 60-kilometre-long, oval-shaped geological formation known as the Sudbury Basin. Nickel and copper are the primary metals produced, but cobalt and precious metals such as platinum and palladium are also recovered. The Geodynamics Group visited two Falconbridge mines: Craig Mine and Fraser Mine. Images courtesy of Andrew Daly.
