An underground copper mine consisting of three shafts, the deepest was 140 ft. and sunk on the Allouez Conglomerate. The "Old" Rhode Island Mining Co. was organized in 1860 and worked contemporaneously with the Albany & Boston Mining Co. After no economic mineralization was found, the mine closed in 1865. The copper boom of 1898 resparked interest in the mine and the "New" Rhode Island Mining Co. was organized in 1899. Work was restarted on the Allouez Conglomerate in the original shafts until 1906 when the mine closed again. In 1910, the Franklin Mining Co. took over operations and quickly abandoned the conglomerate in favor of the richer Pewabic lode, which crossed the property. Work continued sporadically until 1920, when the mine was closed for good. The mine piles today yield fine specimens of copper, epidote, and quartz. Recently, some large analcime crystals were discovered.
