Mineralization Comments

Aug 14, 2024 (Therese Pettigrew) - Harding (1951) notes that two pits were sunk on the property located "a few yards east and parallel to the Canadian Pacific Railway. ... The pits are less than 100 yards apart. The larger pit, which lies about 100 feet from the railway, is 20 feet long and 10 feet wide; its depth was not ascertained because the location is on low ground and the excavation was filled with water. The smaller pit, which is about 250 from the railway, has a diameter of about 25 feet and is 12 feet deep. Pink potash feldspar containing disseminated quartz and biotite was exposed in both workings. No large body of pure feldspar was visible in either pit. The large pegmatite dike in which the pits are situated appears to consist predominantly of pink potash feldspar, with minor amounts of quartz and biotite." De Schmid (1916) describes the property as being "owned by Mr. J. M. Stoness, of Perth Road, who has had three men engaged in prospecting the property for a couple of months. A few small surface pits have been opened, all of which display a similar type of rock. The deposit is of the usual pink microcline class, having a direction of N. 60 E, and possessing a graphic-granite character and structure. The country rock is a dark coloured gneiss or schist, and a considerable amount of biotite mica is present in the dike, on and adjacent to the northwest contact with the enclosing rock. The same mineral is frequently met with on joints and seams in the mass of the dike, and constitutes a deleterious constituent necessitating careful cobbing of the feldspar before the latter can be utilized for pottery purposes. The width and extent of the spar body have not been ascertained, but the mineral has been found over a considerable area. It occurs in the form of more or less parallel ridges or "hogsbacks," which rise some 50 feet above the level of the intervening swamp land, the width of 210 the largest ridge being about 100 feet and its length 500 feet. These ridges seem to constitute a series of parallel dikes of feldspar, and are separated by narrow belts of dark schist."
