Two fish-bearing creeks will be used for 2.3 billion tons of toxic tailings from the proposed Kerr-Sulphurets-Mitchell (KSM) mine in northwest B.C., wiping out habitat for several populations of small Dolly Varden fish.
Seabridge Gold Inc. has been given federal government approval to use upper tributaries of the North Treaty and South Teigen Creeks, which flow into the Nass and Bell-Irving rivers, for tailings from the planned gold, copper and molybdenum mine 65 kilometers northwest of Stewart and 30 kilometers from the Alaska border.
Once in operation, KSM is set to become the largest open pit mine in North America. Construction is set to begin in 2017.
