Point Location Description: Precise
Location Method: Data Compilation
Access Description: 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. Ten chains north of the road, near the top of a hill, a trench 45 ft. and 4 to 5 feet wide and 8 ft. deep was put down on a carbonate vein cutting a graphic granite-pegmatite.
1900: The mine was worked around 1900. There are several pits and an adit. The deposits were worked about 1900 and the apatite crystals were hand-cobbed for shipment. There is no recorded production 1979: Imperial Oil Limited - conducted a geological and radiometric survey for uranium. 1981: Some blasting had taken place. 1993-1998: Sharpmin Developments Inc. Stripping, sampling, trenching, geological mapping and prospecting.

Jan 29, 2017 (A Wilson) - This deposit was at one time worked for apatite, and a considerable quantity of this mineral was taken out. The pegmatite dike or vein, here, cuts a banded quartzite, and is for the most part rather fine in grain, although it varies greatly in size of grain from place to place. Several coarsely crystalline calcite veins containing large anhedral to euhedral crystals of biotite, hornblende, microcline, apatite and minor quartz occur on the property. In addition to these minerals, Sabina (1986) reports thorite, thorianite, uranophane, serpentine, pyroxene and chondrodite for the property.
