OUR open-pit operation

Canadian Malartic Mine is Canada’s largest operating open-pit gold mine.

Its world-class deposit is now estimated at close to 10,000,000 ounces of gold. The mine is located in the Town of Malartic, in the heart of Québec’s Abitibi Gold Belt.

By the numbers
  1. More than 2,000 full-time
    on the mine site in 2020

    • More than 800 CMM employees
    • Nearly 1,300 contractor employees
  2. Continuous

    • 24 hours a day, 7 days a week
    • Nearly 100 pieces of mobile equipment
  3. Our production
    in 2020

    • 20 million tonnes of ore processed at the plant
    • 568,634 ounces of gold produced
  4. Proven and probable
    reserves at December 31, 2020

    • 4.43 million ounces of gold at 1.12 g/t of gold
Ore processing
  • The plant processes 57,000 tonnes of ore per day, on average, depending on operational availability, which was 95.25% in 2020.
  • The plant includes a crushing circuit consisting in primary and secondary crushers, which is followed by a grinding circuit. The milled ore then goes through a leach circuit, where the gold and silver are dissolved and then recovered by absorption on activated charcoal before being poured into bars. The average gold recovery rate at the Canadian Malartic Mine was approximately 87,4% in 2020.


At the end of the mine’s life
  • The pit will be 4 km long, 1,000 metres wide and 390 metres deep.
  • The waste dump will be 100 metres high.


Environmental Performance

The Canadian Malartic Mine has introduced numerous measures to reduce the potential impact of its operations, including:

  • Air quality measuring stations;
  • Dust prediction software;
  • Water trucks to spray roads and loads to reduce dust emission;
  • Acoustic stations;
  • Real-time noise tracking software.

We can completely shut down equipment when dust levels approach the levels permitted by the air quality standard or when noise levels approach the noise limits indicated in municipal by-laws and the Environmental Quality Act.

Equipment was down for more than 13,000 hours in 2019.

In 2020, the Canadian Malartic Mine fully complied with Québec standards governing air* quality, water quality, and noise. Furthermore, compliance with blasting standards was 99.1%.

* Pursuant to the Clean Air Regulation. From May 8, 2015, to December 31, 2020.
