That's not true. In 2014, Prop 4 passed with 64% and read, "This bill would require the legislature to approve future large-scale metallic sulfide mines in the Bristol Bay Fisheries Reserve (BBFR) by passing a law. The law would have to find that any proposed mine would not endanger the BBFR fishery. The approval would be in addition to any other required permits or authorizations." That language is pretty vague and only got that kind of approval thanks to massive spending by Bob Gillam.
