In feldspar-biotite gneiss.
"The quarry is on the western shore of Mill Lake. It is operated by Mr. W.R. Hall for gneiss used as flagstone, and veneer for buildings."
The Mill Lake stone quarry, lots 24 and 25, concession III, McDougall township, on Mill lake, l 1/2 miles from Parry Sound, was formerly operated by R. R. Hall and is now run by his son, J. Hall. The deposit has been described by Parks. The rock is a finely laminated, pink, grey, and white biotite gneiss of sedimentary origin. Strong partings occur from 2 to 4 feet apart, and there are well-developed joints. The rock splits readily parallel to the gneissic structure and makes excellent flagstones. As a building stone it was used in the Court House and Registry Office foundations in Parry Sound. The deposit has been worked intermittently from 1900 (?) to the present time. All operations are carried out by hand. No record of production is available prior to 1923. From 1923 to 1941, inclusive, the total production was valued at |2,073. In 1941 flag stones sold for 6 cents per square foot, and building stone for $6 per cord (4 by 4 by 8 feet).
