Introduction
An underground copper mine consisting of two shafts located north of Ripley Ripley.

History
The Concord Mining Company was organized in 1864 after 160 acres of land was set off from the Franklin Mining Company. The company was organized by Franklin investors to work a portion of the Arcadian Lode. Two shafts were sunk in 1864 with some success in recovering copper. In 1868, the Concord was consolidated with the nearby Pewabic Mine and worked on tribute until 1874 when the mine was abandoned. In 1879, the Concord was set off from the Pewabic as a separate company but mismanagement plagued the new company. In 1898, the Concord was absorbed by the Arcadian Copper Company; the original Concord shafts becoming Arcadian Nos. 1 and 2 shafts.

Production
The Concord produced over 300 tons of copper during its life.

For the Collector
Very little remains of the rock piles; most of it was used when the local airport expanded its runways. Copper and datolite have been found here.
