An underground copper mine consisting of two shafts located directly north of the Pewabic Mine. The Franklin Mining Co. organized in 1857 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 Co. approx three miles north of the old Franklin Mine and renamed it Franklin Jr. Mine. More about this mine can be found on the "Franklin Jr. Mine" listing. In 1908, the original mine property was sold to Quincy.
