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 1.
It contains old mining journals, beautiful bornite specimens from 5000' below the surface, old miners' safety hats, and a written history of Magma Mining in Superior.
