The Douglas Mine was an open pit mine near Chisholm, Minnesota operated by the M. A. Hanna Company. The M. A. Hanna Company was one of the large mining companies that moved into the Great Lakes iron area in the early 1900s, consolidated smaller properties, and engaged in exploration for other economic deposits. The Company was dissolved in 1965, then resurrected in 1985.
