The Franklin Mining Company began operations in 1857 in Hancock, Michigan. It consisted of two shafts located directly north of the Pewabic Mine and worked the Pewabic Lode. Because management neglected to purchase the land north and west of their property, it soon became boxed in by the Quincy Mining Co. and by 1880 had exhausted its share of the Pewabic Lode on its property. In 1894, the company purchased land originally held by the Albany & Boston Mining Company and renamed it Franklin Jr. Mine. In 1909 the Franklin Mining Company was sold to the Quincy Mining Company.
