Topaz deposits near the Brewer mine, Chesterfield County, South Carolina

Lode and placer deposits of massive topaz rock were discovered near the old Brewer gold mine in northwestern Chesterfield County, S.C., in 1935. Preliminary tests have shown that this rock ca be used in the manufacture of refractory ware and as a source of mullite, thus augmenting supplies of kyanite that have been coming from India. About 700 tons of topaz rock had been mined up to August 1941, largely for experimental uses.
