Comment: 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.
Minerals: Quartz (SiO2) Siderite (Fe++CO3)
