George Warren worked as a prospector in the Tombstone and Bisbee, Arizona region during the late 19th century. He is credited with having located the body of copper ore, which later was known as the Copper Queen Mine, one of Arizona's most productive copper mines. Warren drank too much and bet his interest in the mine on a foot race against a horse and lost.

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.
