History

From its beginnings in 1860 to the end of World War II, Copperopolis has been directly related to and affected by the extraction and production of copper ore. Copper was first discovered in the area in 1860 by Hiram Hughes on Gopher Ridge at Quail Hill, and a few months later at the Napoleon Mine on Hog Hill, about six miles southwest of Copperopolis. Shortly thereafter a copper-bearing “gossan” was discovered by W.K. Reed and Thomas McCarty in the Copper Cañon Mining District, on the Union Copper Claim, and a short time later a second strike was made on the Keystone Claim. Other important claims included the Calaveras and the Empire. One year later the community that developed around the strikes became known as Copperopolis, the name derived from the word “copper,” plus the Greek word “polis” meaning city.
