A locomotive labeled "Hanna Ore Mining Company 304" is shown pulling loaded ore cars for the Mississippi Group mines. The Mississippi mines include the old Mississippi Mine and consist of a group of open pit and underground mines Keewatin in the Mesabi Range, Itasca County, Minnesota. The mines were operated by the Hanna Ore Mining Company (M. A. Hanna Company) into the 1950s. The M. A. Hanna Company was one of the large mining companies that moved into the iron areas of the Lake Superior region in the early 1900s, consolidating smaller properties and engaging in exploration for other economic deposits. The Company was dissolved in 1965, then resurrected in 1985.
