Northwestern Regional Office
The Northwest Regional Office is responsible for the management of 4 District Offices--Kenora, Red Lake, Thunder Bay North and Thunder Bay South. The resulting area is approximately 700 km by 700 km in size, from the Manitoba-Ontario border in the west to the vicinity of the town of White River, Ontario, in the east; and from the United States-Canada border in the south to the edge of the James-Hudson Bay lowlands in the north.
The Northwest Regional Office is also home to the First Nation Minerals Information Officer, who provides information and expertise to Ontario First Nations communities in particular. Although the First Nation Minerals Information Officer is based in Thunder Bay, his services are delivered throughout Ontario.
Metallic mineral commodities produced in the Northwest Region include gold, palladium, platinum, silver, copper and nickel. The Northwest hosts 5 producing gold mines: Red Lake Mine, Musselwhite Mine, William Mine, David Bell Mine, and Lac Des Iles Mine. Non-metallic mineral commodities produced in the Region include granite dimension stone and amethyst, the latter being Ontario's official gemstone.

Red Lake District Office

The Red Lake District Office is located in Red Lake, Ontario. The present town of Red Lake was created in 1998 by the amalgamation of the Townships of Red Lake, Golden (the Balmertown, Cochenour and McKenzie Island townsites) and the Madsen Local Services Board. The District also includes the community of Ear Falls and many First Nation communities which are accessible only by air or winter road.
Historically, gold is the main commodity produced in the Red Lake District, although iron was produced from 1968 to 1986 at the Griffith Mine near Ear Falls and zinc, copper and silver were produced from the South Bay Mine from 1971 to 1981. Since 1930, over 23 million ounces of gold have been produced in the Red Lake District, the bulk of it (approximately 18 million ounces) from the Campbell-Red Lake Deposit, now operated as The Red Lake Gold Mines by Goldcorp Inc.
