In biotite paragneiss.

"The deposit was worked for graphite from 1912 to 1915 by New York Graphite Company. The openings consist of several pits and an adit along the north slope of a ridge, the largest pit measuring 18 m by 4.5 m and 12 m deep. A three-story mill was built at the base of the ridge and treated ore from this deposit and from the National Graphite Mine."
