We note that the True Blue property was rediscovered by searching through a private database (although the beryl was originally misidentified as kyanite, a sample was retained and was later identified using X-ray diffraction). a three-year, $254,500 project to update the inventory of industrial minerals such as building stone, graphite, quartzite, kyanite, vermiculite and silica in the Parry Sound and Nipissing districts. The basal gravels are comprised of a clast supported gravel horizon comprised largely of well-sorted quartz cobbles and quartzite boulders, within a matrix of quartz-rich sands that host a visible concentration of heavy minerals such as gold, tourmaline, ilmenite, kyanite, topaz, and sapphire. |
