Arizona members of Congress and the U.S. Senate have reintroduced legislation for a proposed 7,000-foot-deep copper mine near Superior.
U.S. Reps. Paul Gosar and Ann Kirkpatrick claim the Southeast Arizona Land Exchange and Conservation Act could create more than 3,700 jobs.
U.S. Sens. John McCain and Jeff Flake say the mine would generate more than $64 billion in economic activity and tax revenue and could supply as much as 20 percent of the nation's domestic copper demand.
Kirkpatrick's district includes the proposed mine site. She acknowledges longstanding opposition to the mine from tribes and environmental groups.
Under the bill, Resolution Copper Mining Co. would exchange more than 5,000 acres of environmentally sensitive land the company owns throughout Arizona for about 2,400 acres of federal land 70 miles east of Phoenix.
