The Abitibi: Canada’s Largest Gold District
Canada is home to many great gold districts, but none come close to the Abitibi greenstone belt.
Having produced over 200 million ounces of gold since 1901, the Abitibi belt has etched its place as Canada’s largest gold district. Today, the region is bustling with exploration activity and hosts three of the country’s largest gold mines.
The above infographic from Maple Gold Mines showcases what makes the Abitibi a prolific gold district, from its history and geology to current activity and the potential for discovery.
The Abitibi Greenstone Belt: Remarkable Geology and History
Over 2.6 billion years ago, the Earth’s natural processes of creation and destruction resulted in the formation of metal-rich volcanic rocks and deformation zones that comprise the Abitibi greenstone belt.
The Abitibi belt hosts several economically viable deposits of gold, silver, zinc, iron, copper, and other base metals. The types of deposits found there include gold-rich quartz-carbonate veins, copper porphyries, and volcanogenic massive sulfide (VMS) deposits.
Since mining began in the early 1900s, more than 124 mines have been set up in the Abitibi, and at least 15 of these have yielded over 3.5 million ounces of gold. What’s more, the total gold content of the belt, including past production and current reserves and resources, exceeds 300 million ounces.
The majority of the Abitibi’s rich gold deposits lie along fault lines in major deformation zones such as the Cadillac-Larder Lake (Read more...)
