We will sample water prior to discharge and validate against Metal and Diamond Mining Effl uent regulation (MDMER). If the water meets the criteria, we will discharge a certain quantity per day as per the approval we received.

Modelling showed that the water will mix within a few meters from the diffuser once it is discharged into Melvin Bay and it will not contaminate the bay.

We will also conduct additional monitoring as per MDMER such as sampling around the diffuser location, biological studies in the receiving environment, etc. The Hunters and Trappers Organization (HTO) will also be involved in the monitoring.

Note that the purpose of the MDMER is to reduce threats to fi sh and their habitat by improving the management of harmful substances in metal and diamond mining effl uent. You can fi nd more information on their regulations by visiting the following website: https://laws-lois.justice.gc.ca/
