Although the mine was worked in the 1800s, it was closed about 1948, and did not reopen until 1979.[5]
In 1985 the mine was producing over 72,000 metric tons of ore per day.[6] In addition to copper, it produced silver as a byproduct, in 1995 that amounted to over 77 tons of silver.[7] The mine was repurchased by investors from the Mexican government in 1988.[8] The mine employed approximately 3,000 workers in 2000.[9] In 2006 the mine was shut down due to labor strikes.[10]
