Gold mines in the Carolina Slate Belt - USGS.
South Carolina had a number of lode gold mines along the Carolina Slate Belt.
The Haile deposit was discovered in Lancaster County in 1827, and at least 275 thousand ounces of gold were extracted intermittently between then and 1942, when the gold mine was ordered closed as nonessential to the war effort. Beginning in 1951, the deposit was mined for associated sericite, which was used as a white filler. Gold is associated with silicic, kaolinitic, and pyritic alteration of greenschist-grade felsic metavolcanics. The mine was reopened as an open pit in the 1980s, and operated until 1992. Kinross Gold Corporation's reclamation of the Haile site was nominated for a US Bureau of Land Management "Hardrock Mineral Environmental Award."
The Brewer mine operated from 1828 to 1995, and is now a federal Superfund site.
Kennecott Minerals operated the Ridgeway open-pit gold mine from 1988 to 1999, and the land is now being reclaimed by Kennecott.
The Barite Hill mine operated from 1990 to 1994.
