Letter urges Hobbs to prevent turning trust lands into 'dumping grounds' for mine waste

Despite Resolution Copper recently acquiring 2,422 acres of federal lands through a decade-old congressional exchange, the company still needs Arizona land to hold all of the waste the massive mine could produce during its six decade lifetime.

Opposition is mounting against this proposal in a Monday letter to Gov. Katie Hobbs.

More than 50 groups — including the Center for Biological Diversity, Apache Stronghold and the Arizona Mining Reform Coalition — are urging the state Land Department under Hobbs not to sell or lease anything to Resolution Copper.

Without such a deal, the multinational mining company could be left with nowhere to build a needed tailings storage facility. For now, the plan is to erect a nearly three-mile-long, 500-foot-high dam just north of the Gila River.

Skunk Camp could one day store about 1.4 billion tons of mine waste. The roughly 8,200-acre site is located in the Dripping Springs Valley — east of Coolidge Dam near the historic copper mining town of Kearny.

Resolution Copper wants to dig up a massive amount of copper ore beneath Oak Flat inside the Tonto National Forest. And by doing so, a site that some Apaches consider sacred may be destroyed.

“Arizonans would bear the environmental risks ... while foreign investors reap the profits,” the letter claims. Its authors are asking the Hobbs administration to stand with Arizonans by denying any proposal that would turn state trust lands into a “permanent dumping ground for foreign-owned mining operations.”

In response to the letter, Resolution Copper told KJZZ that this proposed tailings facility “has undergone independent, third-party expert reviews for safety, stability, and water quality,” adding that its location was selected through consultations with communities, including tribes, and was even changed based on their feedback.

Meanwhile, Hobbs has yet to weigh in.
