Vale continues to update their dams

Vale continues to upgrade its tailings dam infrastructure in Greater Sudbury. In the last 15 years, the mining company has upgraded five dams in the Copper Cliff region which were built using what the industry calls the upstream method. The five upgraded dams were reinforced to withstand the maximum credible earthquake possible in Greater Sudbury. The remaining six dams are expected to be upgraded in the next six or seven years.
