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 2019

    • More than 770 CMM employees
    • More than 1,300 contractor employees
  2. Continuous

    • 24 hours a day, 7 days a week
    • Nearly 100 pieces of mobile equipment
  3. Our production
    in 2019

    • 21 million tonnes of ore extracted
    • 669,192 ounces of gold produced
  4. Proven and probable
    reserves at December 31, 2019

    • 4.78 million ounces of gold at 1.11 g/t of gold


Ore processing
  • The plant processes 57,000 tonnes of ore per day, on average, depending on operational availability, which was 94.2% in 2019.
  • 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 CMM was approximately 88.5% in 2019.


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

CMM 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.

CMM can completely shuts 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 2019, CMM fully complied with Québec standards governing air* quality, water quality, and noise. Furthermore, compliance with blasting standards was 98.6%.

* Pursuant to the Clean Air Regulation. From May 8, 2015, to December 31, 2019.
