Feds use rare veto to block Alaska copper, gold mine plan

JUNEAU, Alaska (AP) — The U.S. Environmental Protection Agency on Tuesday effectively vetoed a proposed open-pit copper and gold mine in a remote region of southwest Alaska that is a trove of minerals coveted by mining interests but that also supports the world’s largest sockeye salmon fishery.
