Nov 21, 2013 (A Wilson) - The Potsdam sandstone is grey to white to brown and has a thickness of 20-147 feet. The sandstone is comprised of light grey to buff-grey, sub-angular to rounded quartz grains within a siliceous matrix. The sandstone is fine- to medium-grained, and pyrite is found in fractures in the grains. A 1 m interval of sandstone containing quartz pebble beds was observed at the unconformity between the Paleozoic rocks and the Precambrian basement.

Nov 21, 2013 (A Wilson) - The grains are subangular to well-rounded. There is some iron staining, but the main iron-bearing impurity is pyrite that occurs in minute grains intergrown with the quartz. The ore zone ranged in depth from 5.5 to 44.8. Laboratory tests showed that a range of silica products could be produced. Beneficiation of the sand would be required in order to produce a glass sand. Iron analyses ranged from 0.14 to 0.45% Fe2 O3 The +100 mesh product from the leached silica product analyzed 0.065% Fe2 O3 and 0.14% Al2 O3 . The -100 mesh fraction analyzed 0.058% Fe2 O3 and 0.47% Al2 O3 . The original results (1958) were considered to be unsatisfactory. Canadian Silica estimated the ore zone to average 5.8 m in depth. A hole drilled by the Ministry of Natural Resources in 1978 returned an average assay of: 96.10% SiO2, 0.32% Fe2O3, 1.28% Al2O3, 0.06% MgO and 1.84% CaO.
