Gunnislake Clitters Mine produced Copper, Arsenic, Tin, Tungsten. "Old Gunnislake" just to the south, together with the Wheal Tamar, had been worked for copper in the 1700s. Uranium was found in both, but not mined. The mine forms part of the estate of the Duke of Cornwall.
Gunnislake Clitters Mine was worked from 1820-1919, first by an adit from the valley side and later by shafts. Before the construction of the East Cornwall Mineral Railway, a tramroad linked the mine to wharves at Gunnislake.
The mine is on the steep valley side and was neglected after closure. The Cornwall Archaeological Unit has been involved in strengthening weakened buildings, fencing dangerous areas and providing safe routes through the site.
