Continue on the road another 1.28 km and veer right just past an old log building; the Davis Quarry is at the end of the road.
Mineral location - several varieties. 1940-42 : opened by the Canadian Flint and Spar Co Ltd and produced 944 tons. The workings consist of a main quarry (30 x 12 m) and a small cut (6 x 6 m ) N of this as well as a slash in the hill 10.5 m W of the main pit. Faces are 10-25 ft high.
Province: Grenville
Geological Age: Mesoproterozoic
Dec 07, 2005 (C Papertzian) - The quarry is in a coarse-grained nepheline pegmatite (hosted in nepheline-plagioclase gneiss and nepheline amphibolite) made up of predominantly nepheline and albite with accessory microcline, tourmaline, biotite, zircon, apatite, cancrinite, gieseckite, muscovite, hackmanite (good specimens) and galena as well as some calcite and allanite. Zircons measuring about 4 inches in length and weighing up to 3 lbs are reported; nephelines have reached 12 ft in size. The pegmatite bifurcates about 15 m N of the main quarry. It is about 100 m long in exposure and up to 30 m wide at the main quarry, 10 m to the N. The pegmatite was drilled in 1976.
