In crystalline and silicated limestone; in pegmatite.

"The deposit was worked by several pits over a distance of 500 m. Two companies were involved in mining operations: the Tonkin-Dupont Graphite Company in the eastern section of the orebody from 1912 to 1914, and National Graphite Company in the continuation on the western section from 1915 to 1919. Both companies operated mills for the treatment of the ore; the Tonkin-Dupont mill was at Wilberforce, that of the National Graphite Company at Mumford Station. Operations terminated due to a decrease in demand for graphite following World War 1. There are nine pits: two water-filled pits are on the east side of the road southeast of the farmhouse and the others extend westward over about 245 m. The largest pits are 61 m by 4-12 m and 23 m deep, and 18 m by 9 m and 46 m deep."
