Perhaps the easiest minesite to visit on the Island, the Smithwick Mine is located very close to the Rock Harbor Lodge. The mine was explored by Captain Smithwick in 1843 with active mining occurring from 1847-1849. Two shafts were dug with the deepest being 90 feet. On the surface, a blacksmith shop, dwellings, and a large root cellar were built. After three years of activity, the mine was not economic and abandoned shortly thereafter. No record of copper production is noted.

Today, the mine is easily visited from the Lodge. The National Park Service has erected signs around the site describing the operations. As this is a national park, collecting is strictly forbidden.
