Answer 2

The most significant geological formation associated with metal mining in Canada is the Canadian Shield. The shield is the largest and oldest geological region in Canada. It was formed 4 billion to 570 million years ago, and is composed of igneous and sedimentary rocks that have been heavily metamorphosed over the hundreds of millions of years of its existence.

The Canadian Shield represents about half of the land area of Canada. The shield comprises the Bear, Slave, Churchill, Superior, Southern, Grenville and Nain geological provinces. It forms a great circle around Hudson's Bay, extending from the eastern Northwest Territories and southern Nunavut, through northeastern Alberta, northern Saskatchewan and Manitoba, western and central Ontario, and most of Quebec north of the St. Lawrence River, to Labrador and Baffin Island.

The majority of Canada’s metal mines are on the Canadian Shield. They are found in an arc stretching southeast from the gold mines of Yellowknife, through Flin Flon, Red Lake, Timmins, Sudbury, Rouyn-Noranda, Val d’Or and Chibougamau, to the iron mines of Labrador City.

Hope this helps ...
