Name one open pit mine that hasn't had its safety measures malfunction. A malfunction to this particular watershed could potentially crash the sockeye fishery. According to the Bristol Bay Economic report, the fishery brings in 1.5 billion dollars annually. If that fishery is destroyed by the mine, that's 1.5 billion dollars of annual revenue gone and thousands of jobs lost. It doesn't make fiscal sense to mine the area. There are many other places to mine copper that have far less at stake.
