SUPERIOR, Ariz. (AP) - An Arizona congresswoman says she'll work to revive a stalled land exchange that would allow for the expansion of a copper mine.
U.S. Rep. Ann Kirkpatrick recently visited Superior to express support for the expansion project. She says she'll work to introduce new legislation in Congress that includes environmental protections.
Under a proposal that has been pending since 2005, Resolution Copper Mining would swap 5,300 acres of land for conservation purposes for 2,400 acres of national forest land that holds 1 of the largest undeveloped copper resources in the world.
Opposition by conservationists and some American Indian groups has helped stall the exchange.
Resolution Copper has said it will invest more than $6 billion in the proposed mine.
