Radiogenic isotope compositions of neodymium and lead indicate that the gold deposits are underlain by deep-seated rocks (basements), which are not found west of the Carolina slate belt, but which occur as part of a trend that stretches to the northeast and southwest for hundreds of miles.

This region is thought to have major potential for containing large undiscovered deposits of gold and silver, as well as copper, lead, zinc, molybdenum, and tin. Gold production from the major mines (Haile, Brewer, Ridgeway, and Barite Hill) in South Carolina ranked sixth in the Nation in 1992.
The Carolina Slate Belt is highly prospective for many types of gold ore hosted within quartz-sericite-pyrite altered volcanic rocks, juvenile metasedimentary rocks, and in associated shear zones.
Today I am going to talk about the age and origin of Neoproterozoic gold deposits that occur within the Carolina Slate Belt (Slate Belt) in the southeastern United States. This presentation includes an up-to-date summary of the results of studies conducted in the region by a U.S. Geological Survey group led by Robert A. Ayuso.
Exploration strategies for large-scale gold-mineralizing systems applied to rocks of the Carolina Slate Belt, and by extension, the Carolinian-Avalonian tectonic zone of North America, benefit from applying subvolcanic and basinal epithermal models for gold mineralization.
