Jul 06, 2012 (P Sangster) - The Bar River Formation quartzite consists of a lower unit of white quartzite, approximately 370 m thick, and an upper unit of interbedded quartzite, argillite and siltstone, approximately 550 m in thickness. The outcrop of the quartzite formation on Badgeley Island is 1525 m long by 300 m wide. The ore zone within this formation is part of the lower member of the Bar River Formation sandstone, and is 760 m long by 1590 m wide. It is in conformable contact with the Gordon Lake Formation to the northeast and in unconformable contact with the Lindsay Formation to the northwest and southwest. To the southeast it is in unconformable contact with the Killarney granitic intrusion, mapped as a quartz diorite. Ripple marks and cross-bedding are common. The beds are 0.1 m to 1.0 m thick, in medium-grained, white to buff quartzite. There has been no major faulting in this section of the Bar River Formation, but folding has been extensive and the beds are now vertical to overturned. Two amphibolite dikes cut the orebody, one 250 m east of its western limit, and the second forms the western limit. The dikes have not introduced any appreciable contaminants into the quartzite. Alumina, iron, and titanium are present and are associated with sericite seams. These seams can be segregated visually from the ore-grade material.

Jul 06, 2012 (P Sangster) - Lump quartzite from the Badgeley Island quarry (150 000 t/y capacity) in northern Georgian Bay was shipped by lake vessel to Canadian destinations for the manufacture of ferrosilicon. Preliminary crushing and grinding at the quarry produced a finer material that was shipped to the Unimin plant at Midland (400 000 t/y capacity), south of Georgian Bay, for further processing to glass-grade silica sand and to silica flour for ceramic and other uses.
