Exploration Of The Kings Mountain Pegmatites

With only six small spodumene prospect pits, no detailed mapping, and no subsurface information in 1938, the Carolina lithium-pegmatite area now contains four mines among more than 25 properties on which exploratory work has been done. Even the open pit mine of Foote Mineral Co. described herein, from which ten million tons of ore and waste have been removed since 1952, was virgin ground when mapped in 1938-40 1. It has been a privilege to participate in the transition. In 1940, the spodumene pegmatites were known in a 25-mile belt (originally noted for tin prospecting) between Lincolnton, N. C. and Grover at the South Carolina line. Subsequently, Broadhurst 2 reported relatively small bodies northeast of Lincolnton near the Catawba County line. To the south, diamond drilling done in 1953 on the old Ross tin-mine property near Gaffney yielded pegmatite cores containing a few crystals of spodumene. This fact, not previously reported, suggests that some of the pyroxene in the Ross shaft as described by Sloan 3 may be spodumene.
