An underground copper mine consisting of three shafts and located in the city of Hancock. The Hancock Mining Company was organized in 1859 and worked the Sumner (Pewabic) Lode through three shafts; Shaft No. 1 was approx. 1,000 feet. The other two shafts, the Dupuis and the Hill, were about 200 feet deep. Mining continued until 1872 when the original lease ran out and the mine was sold. In 1873, the Sumner Mining Company was organized and worked the mine until 1880, when it was sold to the Hancock Copper Mining Company. In 1906, the company was reorganized into the Hancock Consolidated Mining Company and work resumed in the No. 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 feet and a crosscut was driven at this depth that intersected with the No. 7 Quincy shaft. All work ceased in 1919. The Hancock Mine produced approximately 17.5 million pounds of refined copper. Other than the shaft openings (which have been covered), nothing remains of this mine.
