Decision details
A Notice amending Environmental Compliance Approval (ECA) No. 7435-BW4KJM was issued to Evolution Mining Gold Operations Ltd. for industrial sewage works servicing the Red Lake Operations located in Balmertown, Municipality of Red Lake, District of Kenora, Ontario.
The proposal described in Evolution Mining Gold Operations Ltd.'s application dated February 28, 2024 and revised on July 8, 2025 to amend the ECA No. 7435-BW4KJM is for the following activities:
- Deposit of Campbell Mill tailings into the Red Lake Tailings Storage Facility (Tailings Management Area) to facilitate closure of the Campbell Tailings Storage Facility.
- Upgrades to the mine wastewater treatment plant to handle arsenic, heavy metals and ammonia.
This approval amendment notice approves part of the application to amend ECA No. 7435-BW4KJMM by approving the construction of the following:
- a Tailings Slurry Transference Pipeline, from the adjacent Campbell Mill to the Tailings Area #1 of Red Lake Tailing Management Area;
- North Saddle Dam to complete the perimeter of the Tailings Area #1 to the approved of crest elevation 378 m; and
- upgrades of wastewater treatment plant including retrofitting existing Actiflo treatment system to a metal precipitation reactor treatment system, and the addition of a new Actiflo treatment system.
The Director has determined that it is necessary for environmental protection purposes to approve the above-listed construction activities as these are time-critical activities that need to be constructed before prohibitive winter weather conditions set in and to ensure environmental protection. The ECA includes a condition prohibiting the operation of the Tailings Slurry Transference Pipeline or the upgraded mine wastewater treatment plant upon completion of construction except for testing purposes.
The Director has also posted for consultation a related instrument proposal for the operation of the works and associated conditions including conditions for monitoring, reporting, assessment, and effluent objectives and compliance limits.

If you’re an Ontario resident, you can start the process to appeal this instrument decision.

If the appellate body grants leave, the appeal itself will follow.
