Sample Collection on Lac Hélène, February 28 to March 3

As part of the environmental impact assessment, samples aimed at analyzing lake sediments will be taken on Lac Hélène between February 28 and March 3.

The work will involve taking a maximum of eight samples from four different stations – no more than two samples per station – using a vibracorer placed directly on the lake ice.

Figure 1 shows the location of the proposed stations. In the event of a problem, such as inadequate ice conditions at a particular location, the station could be relocated nearby.

Residents of the Évain sector told us that they observed a fluctuation in the water level of Lac Hélène in the past. The crew from WSP, which will carry out the work, will review existing data on the lake's hydrology by taking surface water samples. They will also conduct a hydrological assessment to establish current conditions as well as predictive simulations to ascertain the potential impacts of the future mine on the lake's water level – a point raised by area residents. At this time, the potential impacts are estimated to be minimal.

This exercise should not create a disturbance in the natural environment or for people living near the lake. The work will take place during the day, supervised by our project superintendent. Access to the lake will be by snowmobile via public land on the north shore of the lake.
