Canadian Malartic Mine

ONE OF Canada’s largest operating open-pit gold mineS

Located in the Town of Malartic, in the heart of Québec’s Abitibi Gold Belt, we are one of Canada’s largest operating open-pit gold mines. With its Barnat open pit, the Canadian Malartic Mine will continue to operate until 2029.

Developing the Barnat gold deposit, which is an extension of the current pit, is the result of the Malartic Extension Project. Started in 2017, this project first consisted of the construction of a 4-kilometre or so deviation of Route 117 to the east of the Town of Malartic. The deviation was opened to traffic in the fall of 2019 allowing the pre-commercial production of the Barnat pit.

THE MINE IN DETAIL

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 18,700 hours in 2024.

In 2022, the Canadian Malartic Mine fully complied with Québec standards governing air* quality, water quality, and noise. Furthermore, compliance with blasting standards was 99.9%.

* Pursuant to the Clean Air Regulation. From May 8, 2015, to December 31, 2024.

ORE PROCESSING

In 2024, 55,512 tonnes of ore was processed daily at the plant, for an operating ratio of 93.6%.
The plant consists in a primary and secondary crushing circuit, followed by a grinding circuit. The milled ore goes through a leach circuit, where the gold and silver are dissolved. Both dissolved precious metals are subsequently recovered by a circuit that uses activated charcoal before being poured into bars. The average gold recovery rate at CMM was approximately 92.4% in 2024.

AT THE END OF THE MINE’S LIFE

The Canadian Malartic pit, whose activities have officially ended on May 5, 2023, was 1.8 km long, 1 km wide and 360 metres deep.
The Barnat pit will be 1.7 km long, 750 metres wide and 380 metres deep.
The waste dump will be 100 metres high.

RESTORATION

When mining ceases, we plan to, among other things:

Revegetate the entire tailings pond and waste rock pile, as well as other industrial surfaces.
At the end of underground mine operations, allow the pits to flood with natural groundwater and precipitation, thus covering the mine tailings and waste rock generated by Barnat open-pit and Odyssey underground mine operations and stored in the Canadian Malartic pit.
Secure the site, restore its natural appearance, and conduct all required environmental monitoring.
