Gaffney Area — Kings Mountain Tin Belt (Ross Tin Mine)
About this location
Gaffney, in Cherokee County, South Carolina, sits within the Kings Mountain tin belt — a pegmatite-hosted mineral belt straddling the North Carolina-South Carolina line that was, in the early 1900s, one of the only significant tin-producing districts in the United States. The Ross Tin Mine in East Gaffney, discovered in 1902 by S.S. Ross, is the best-documented historic mine here, worked for cassiterite (tin ore) alongside feldspar, kyanite, quartz, and pyrrhotite from the belt's pegmatites and metamorphic rock. Tin mining here proved uneconomic over time, and the district's later production shifted to spodumene (a lithium ore) instead. The Ross Tin Mine is inactive today, with no indication of reopening or public access.
