In calcite veins cutting graphic granite pegmatite.

Was opened around 1900 as a radioactive mineral and phosphate prospect and consists of two open-cuts, two trenches, and an adit (9 m long).

Old workings for apatite on lot 15, concession XI, Monmouth township, are
situated north and south of the road that parallels the south boundary of the lot. In the southwest corner of the lot are several pits and an adit, all of which are overgrown with vegetation. The adit is driven north into the side of a hill for a length of 30 feet. White carbonate veins containing pale-green apatite crystals are exposed in these workings.
Ten chains north of the road, near the top of a hill, a trench 45 feet long, 4 to 5 feet wide, and 8 feet deep was put down on a carbonate vein cutting a
graphic granite-pegmatite. Remnants of carbonate on the walls of the trench
indicate that the vein may have been from 2 to 5 feet wide, trending N. 400 W. The vein can be traced northwest for 60 feet beyond the trench. The walls of the trench are covered with pink feldspar crystals from 2 to 6 inches in diameter and dark-green hornblende crystals from 3 to 6 inches in diameter. Dump material shows books of dark mica with a maximum diameter of 9 inches, minor amounts of titanite, and crystals of green apatite from l to 4 inches in diameter. This deposit is described as Millar's phosphate mine by Adams and Barlow. Ab Gibson of Tory Hill reports that these deposits were worked about 1900, the apatite crystals being hand-cobbed for shipment. There is, however, no recorded production.
