The Bornite Copper deposits were discovered in the 1950 & at no time has it ever been financially feasible to mine, due to the logistics. This, like the other mega projects (the most ridiculous of which is the LNG PipeDream) are unconscionably expensive projects that benefit only the planners &, if brought to fruition, the big contractors.  Everybody else, especially everyday Alaskans, looses -big time.
