The past producing South Crofty mine began life as a small sett called Penhellick Vean in the 1590s, but absorbed smaller mines around it, becoming South Wheal Crofty in 1854.
Initially a shallow tin mine and then a copper mine, the mine workings went back into the deep tin zone from the 1860s onwards, when copper production began to decline.
In 1906 South Crofty Mine Ltd became the foundation of the modern mine. From the 1890s the mine acquired other setts as the surrounding mines closed. These included New Cook's Kitchen, Tincroft & Carn Brea, North Roskear, South Roskear, and Dolcoath Mine in 1930, to become a huge enterprise nearly 4.5 km in length.
Workings are 731 meters deep and feature 2 shafts: Robinson's man riding shaft at 682 meters & Cook's shaft at 731 meters.
Robinsons Shaft was abandoned in the early 1990's as it was becoming dangerous. All man riding and ore hoisting was then transferred to New Cooks Kitchen shaft. Roskear Shaft was then reconditioned and fitted with a new headframe and winder to serve for emergency egress purposes.
An extensive history of the mine is given in J.A. Buckley's "A History of South Crofty Mine".
Currently (2021), Cornish Metals Exploration have a long-term mining licence.
