Industrial Garnet Mine
Crystals up to 18 cm in diameter. Averaging 2 cm in Biotite schist, some of gem quality. Adjacent to this property at coordinates 46 39' 54" N; 80 10' 26" W is the Industrial Garnet Mine. It is likely that specimens from this property are labelled as coming from the River Valley Garnet Mine so I have put the two properties together into one locality. However there is only one pit on the property and the coordinates are for that pit.
The property was originally owned by the Niagara Garnet Company, which acquired the property during the 1920's and shipped some 800 tons of ore during the late 1940's until the property was taken over by the Industrial Garnet Company in 1956.
The occurrence consists of a garnetiferous zone of mica schist conformable to the enclosing biotite gniess and striking north 50 degrees west with dips of 70 to 80 degrees southwest. At one exposed place the horizontal width is 225 feet. Although the writer traced the deposit for a length of 400 feet, the zone is probably much longer. A pit, 90 feet long and up to 30 feet wide and 30 feet deep has been excavated near the hanging wall of the garnet zone.
Approximately 40 to 50 percent of the zone contains poorly-formed pink garnets up to 7 inches and averaging l inch in size, and containing a moderate amount of inclusions. (J.S. Ross 1959)
