The Copper Queen Mine was a copper mine in Cochise County, Arizona, United States. Its development led to the growth of the surrounding town of Bisbee in the 1880s. Its orebody ran 23% copper, an extraordinarily high grade. It was acquired by Phelps Dodge in 1885.

The Bisbee Deportation was the illegal kidnapping and deportation of about 1,300 striking mine workers, their supporters, and citizen bystanders by 2,000 members of a deputized posse, who arrested them beginning on July 12, 1917, in Bisbee, Arizona. The action was orchestrated by Phelps Dodge, the major mining company in the area, which provided lists of workers and others who were to be arrested to the Cochise County sheriff, Harry C. Wheeler. Those arrested were taken to a local baseball park before being loaded onto cattle cars and deported 200 miles (320 km) to Tres Hermanas in New Mexico. The 16-hour journey was through desert without food and with little water. Once unloaded, the deportees, most without money or transportation, were warned against returning to Bisbee. The US government soon brought in members of the US Army to assist with relocating the deportees to Columbus, New Mexico.
