Located approximately one and three-quarter miles southwest of St Agnes, Cornwall, this site, referred to as Great Wheal Charlotte by Dines, features a wide expanse of barren terrain primarily composed of old mine waste material. Positioned overlooking the sea, the area is a popular destination for walkers, easily accessible via an old trackway from the nearby coast road or through the coastal footpath network. Remnants of an engine house’s bob wall are still present on the site, accompanied by extensive mine waste dumps, largely consisting of relatively barren development rock waste. However, diligent searching reveals certain areas of the dumps containing predominantly sulphide-dominated mineralization, including Sphalerite, Arsenopyrite, and Chalcopyrite. These minerals can occasionally be found as crystalline specimens with some luck. The track leading to the mine from the hamlet of Towan Cross is constructed from mine waste, with low-grade specimens of Sphalerite, Pyrite, and Chalcopyrite occasionally observed within it. Although the mine primarily produced copper, traces of tin were also discovered, albeit not in significant quantities.
