The Miami-Inspiration Mining District has a long history of copper production. Some of its most prominent mining properties include the Inspiration, Miami and Copper Cities mines, which led Arizona’s copper production at intervals during the 20th century.
The area known as Miami was first noted for reddish outcrops that enticed prospectors like Black Jack Newman to invest and develop. Newman’s initial acquisition totaled 13 claims comprised of 260 acres.
With the backing of J. Parke Channing, a successful mining engineer who optioned Newman’s claims, the Miami Copper Co. was formed in 1908 with the financial backing of the Adolph Lewisohn family in New York.
