An underground copper mine consisting of three shafts and located in the city of Hancock. The Hancock Mining Co. was organized in 1859 and worked the Sumner (Pewabic) Lode through three shafts; Shaft #1 was approx. 1,000 ft. The other two shafts, the Dupuis and the Hill, were about 200 ft. deep. Mining continued until 1872 when the original lease ran out and the mine was sold. In 1873, the Sumner Mining Co. was organized and worked the mine until 1880, when it was sold to the Hancock Copper Mining Co. In 1906, the company was reorganized into the Hancock Consolidated Mining Co. and work resumed in the #1 shaft. Work was also started on a new, larger shaft that would intersect the Pewabic Lode at depth. This shaft bottomed out at 4,100 ft and a crosscut was driven at this depth that intersected with the #7 Quincy shaft. All work ceased in 1919. The Hancock Mine produced approx. 17.5 million lbs. of refined copper. Other than the shaft openings (which have been covered), nothing remains of this mine.
