In crystalline limestone.

The deposit was worked for graphite from 1910 to 1913 by the Virginia Graphite Company. The Tonkin-DuPont Graphite Company is successor to the Virginia Graphite Company, having been organized in July, 1913.

The mine consists of an adit, 30 m long, and four pits, the largest measuring 12 m by 23 m and 30 m deep.
