Resolution Copper Receives Rocky Mountain Mining Institute Safety Award

Superior, AZ – Resolution Copper accepted the Rocky Mountain Mining Institute’s (RMMI) 2022 Safety Award for Small Underground Mine. The award recognizes Resolution Copper as the safest among its mining peers across the eight-state RMMI region, including Arizona, Colorado, New Mexico, North Dakota, Montana, Texas, Utah and Wyoming. It provides further evidence of the company’s dedication to safe and responsible mining.

“Safety is paramount to our operations,” said Resolution Copper Project Director Andrew Lye. “This award validates what we care about most at Resolution Copper – creating a safe, efficient mining process that benefits our economy and revitalizes the region.”

The Rocky Mountain Mining Institute compared companies for the prestigious award using incident rate data including Non-Fatal Days Lost (NFDL) and No Days Lost (NDL) rates as reported to the Mine Safety and Health Administration, a division of the U.S Department of Labor whose mission is to foster safe and healthy workplaces in U.S mines.

“Congratulations to all the employees at Resolution Copper on winning this award. Your performance is truly commendable,” said Judy Colgan, Executive Director of the Rocky Mountain Mining Institute.

Resolution Copper’s excellent safety record continues into 2022, as the project has not had a lost-time injury or medical treatment case in the first half of the year.

The Resolution Copper project near Superior, AZ is poised to supply up to one-quarter of the nation’s copper demand, a critical step toward delivering a low-carbon future. The project has the potential to create approximately 3,700 direct and indirect jobs in Arizona. Overall, the project could bring $61 billion in additional economic value to Arizona over the estimated 60-year life of the mine, creating lasting benefits for the region and playing a vital role in the nation’s economic recovery.
