In 1952 Inspiration Mining and Development Company took over the Caribou Lake Mica Mine in McConkey township, District of Parry Sound. The company held 12 claims on the north side of Caribou Lake comprising lots 17, 18, and 19, concessions V and VI, McConkey township. The property is located 6 miles west of the village of Loring, and, when visited by the author, was reached by boat from the Caribou wharf on Caribou Lake.
The property was taken over by Inspiration Mining and Development Company on 15 May 1952, and prospecting and exploration on the property proceeded throughout the summer. Work was done on four showings. In the fall of 1952 work was concentrated on No. 3 showing and muscovite was being produced at the rate of 3,000 pounds per week. Total production in 1952 was reported to be about ten tons of marketable mica.
The pegmatite dike strikes N30°E and has a moderate dip of 30°NW. There appears to be a hanging wall zone 3 to 6 feet thick composed of coarsely crystalline alkali feldspar, sodic plagioclase, quartz and muscovite. Below this there are indications of a core zone of barren quartz. Total thickness is probably about 10-12 feet. The muscovite consists of well-formed books about 3-10 inches in diameter.
