Personally I don't think it's worth risking Bristol Bay and Pebble was just the first mine, there surely would be more.
"Because of the estimated 10 billion tons of mining waste that must be permanently stored in the area, which is an active earthquake zone, and Rio Tinto's environmental track record, which is seen as poor by many environmental advocacy groups, fears have been raised about the potential impact on the Bristol Bay area and its wildlife and residents. In April 2003, the U.S. Environmental Protection Agency issued an assessment of the impact of the proposed mining operations on fisheries, wildlife, and native Alaska tribes. Between 2014 and May 2017, Pebble sued the EPA several times. The company argued the EPA unfairly assumed the scope of the mine before it formally filed mining plans. Northern Dynasty Minerals LLC. accused the government agency of colluding with anti-mine activists to reach its conclusions"
