Magma Mining Company was formed in 1910 in Superior, Arizona. The company mined copper in Superior through 1996 when the last Magma Mine was closed. I have listed the three Magma Mining Company booths in the World's Smallest Museum. Each contains artifacts of the Magma Mining Company Era. This is Booth 2. It contains a 1920's miner's lunch pale, carbide lamps, core samples, a dynamite box from Curtis, Arizona, and an underground telephone.
