The Ray mine is a large copper mine in Pinal County, Arizona, near the town of Kearny, in the southwestern United States. ASARCO, a subsidiary of Grupo México, currently owns the mine, which it acquired from Kennecott Copper in 1986.[1]

The Ray mine has one of the largest copper reserves in the United States, with proven and probable reserves of 835.7 million tonnes (822,500,000 long tons; 921,200,000 short tons) of ore grading 1.73% copper, as of December 31, 2018.[2][3][4] Copper from the Ray mine goes to the Hayden Smelter.
