San Manuel Copper Mine

The San Manuel Copper Mine was a surface and underground porphyry copper mine located in San Manuel, Pinal County, Arizona. Frank Schultz was the original discoverer, in 1879, but the main body of the deposits were discovered by Henry W. Nichols in 1942. The exploration drilling went on from 1943 to 1948, with the first mine shaft built 1948. Louis Lesser developed a mining city to service Nichols’ newly discovered deposits, and the development was completed about 1954. The first major production began in 1955, and the mine and smelter were permanently closed in 2003. The mine is reportedly haunted, though the reports are vague. What can be gleaned from brief accounts is that noises have been heard, where no noises should be heard, and lights have been seen, where no light ought to be seen
