With the U.S. Supreme Court declining to hear a last-ditch appeal, a long-planned Arizona copper mine could break ground in early 2026 and, once fully operational, supply up to 25 percent of the nation’s domestic demand for the critical mineral.
For the second time in five months, the court on Oct. 6 denied Apache Stronghold’s petition to hear its lawsuit challenging a land exchange Resolution Copper needs to build a 7,000-acre copper mine near Superior in Pinal County, 70 miles east of Phoenix and 70 miles north of Tucson, in Arizona’s “Copper Triangle.”
