Tailings management area
It’s all about water
Water quality remains the focus of daily operating practices and capital projects in the Tailings Management Area (TMA). Work for the past six years has involved raising of dams and installing other infrastructure to allow the level of water to be raised in order to better ensure water quality.
The TMA is a collection and settling area for mine discharge and mill tailings. It is important to keep tailings submerged to stop oxidization. Not only will the efforts of the last six years increase the capacity of the TMA, they will also extend the life of Manitoba Operations.
Ensuring water quality is not
only the work of major capital projects. It requires diligent
daily monitoring and discharge practices. Currently, Mill tailings are being discharged into Area
4 of the TMA where water levels are being raised. It is interesting to note that there has been 100% compliance with government
limits for water flowing from the TMA into the Burntwood River.
Another major achievement is in performance measurements of the Towards Sustainable Mining (TSM) performance audits. For the first time, the TMA has received AA scores in every category.
