KSM keeps growing for Seabridge Gold

Another aspect that adds to KSM's capex is the tailings management facility, which alone will cost US$316. The facility would have to accommodate carbon-in-leach sulphide tailings processed with cyanide, and while regulations do not require a lined facility in that circumstance the International Cyanide Management Code recommends using a liner. In the new PEA Seabridge included plans to line part of the facility, adding substantially to the cost.
