The closer you get to the town, the more the explosive charge per delay is reduced. Statistical methods are used to determine seismic wave propagation parameters, which are updated on a regular basis.
Are readings from seismographs located in the town taken by employees of an external firm or by Mine employees?
Environment Department employees take seismograph readings in accordance with a well-established procedure. The seismographs are checked and calibrated once a year by an external firm.
Overpressure is startling and can be disquieting. Blasting air overpressure ranging from 100 to 120 dB has the same impact as 5- to 16-km/hr. winds. Air overpressure of 128 dB, the set maximum standard, has the same impact as 25-km/hr. winds and poses no risk to physical well-being. Air overpressure in excess of 150 dB generally breaks windows. We conduct studies on some town buildings (homes fitted with instruments) to ensure that blasting operations have no impact on buildings.
Yes, Canadian Malartic filed its Environmental Impact Assessment for the Mine Extension and Road Deviation Project on February 13, 2015, with the Québec Ministry of Sustainable Development, Environment and the Fight Against Climate Change.
We must go through an extensive process in order to obtain the permits required to carry out this project. Under the standard process, once the environmental impact assessment is received, specialists at the Québec Ministry of Sustainable Development, Environment and the Fight Against Climate Change, in collaboration with those at other ministries, will first determine if it meets the requirements of the Minister’s directive. Once this has been done, the second step in the Ministry’s process involves forwarding questions to Canadian Malartic’s team of experts, who will provide further details on some aspects of the environmental impact assessment. This usually takes six to nine months. During that period, the impact assessment will be improved in response to exchanges with the Ministry. Under the same standard process, once the environmental impact assessment has been clarified and improved, it is in its final form and deemed officially acceptable by the Ministry. It will be used during the BAPE process, at which point it will be released.
As part of our public involvement process, we will implement a consultation process to address citizens’ concerns. The project will be dealt with during that process.

There are plans to relocate four homes in connection with the deviation of road 117 in accordance with Québec Ministry of Transport regulations. Our team has already met with the residents and will follow up with them in order to keep them informed of the steps taken. No homes will be relocated before the project is accepted.
Please contact our Community Relations Advisors with your complaint or concerns. This enables the Canadian Malartic Mine team to thoroughly understand the nature of your complaint, respond quickly and conduct a thorough follow-up.
