The Copper Era

April 24, 1899, marked the beginning of the Copper Era, a newspaper out of Clifton in Graham (and later Greenlee) County, Arizona. Because Clifton was a mining town, the newspaper included many articles and advertisements related to mining. An article entitled “The London Mining Journal predicts that Arizona will soon pass Michigan and Montana in the production of copper,” appearing  in the June 1, 1899 issue of the Copper Era, shows early evidence that Arizona mining towns were boosting their copper output.
