Mineralization Comments

Jan 15, 2020 (Therese Pettigrew) - The Canoe Lake quartz diorite and related felsic porphyry dikes underlie the entire area of the original property (Davies, 1978). In the vicinity of the workings, the quartz diorite exhibits a faint east-northeast trending foliation. Bow (1899) regards the "vein" to be "a zone of altered granite about four feet wide impregnated with quartz and pyrites" with a strike of north 30 degrees west and a dip of 60 to 80 degrees northeast. He describes a "well defined" footwall, which may be that of the fine-grained granitic dike mapped at the Bullion No. 1 mine, as the strike and dip are similar. Bow (1900) indicates that the altered zone coincides with a plane of faulting in which there is "usually a small stringer of quartz - and small stringers are also occasionally found in the altered zone or vein matter. More or less pyrites is found in the latter and it is said to contain gold all through. The quartz in the plane of faulting is often very rich, considerable visible gold being sometimes found in it". The Canadian Mining Review (1899, p. 145) reported "...ore in bulk in the upper portion of the vein, chiefly Mikadoite, averaged about 54 per ton, as was shown by a test of about 45 tons treated at the Keewatin reduction works. Again by sampling a pile of about 30 tons of the ore taken from a depth of 65 to 80 feet (20 to 24 m), and another pile of 25 tons from a depth of 80 to 90 feet (24 to 27 m), the yield was found to be 54 in the former and 524.20 in the latter (values at 520.00 gold) (Davies and Smith, 1988). A search by Davies and Smith (1988) vein material, although some small quartz-carbonate stringers and veinlets were noted. Rare disseminated sphalerite and chalcopyrite, and minor (up to 2%) pyrite were identified in highly altered quartz diorite. The hanging wall and footwall contacts are well defined, and the footwall quartz diorite is relatively fresh. Alteration is much more intense within the hanging wall, and decreases away from the contact. Rocks on the dump vary from fresh to altered and strongly foliated granite. Green quartz porphyry was also abundant. A sample of altered quartz diorite taken by Davies and Smith, containing visible sphalerite and pyrite mineralization, assayed 10.2 ppm Au and 2.5% zinc. Four similar samples, containing 5%, 3%, 1% and trace pyrite and no sphalerite, assayed 1580, 400, 120 and 70 ppb Au, respectively. A sample of fresh quartz diorite contained 6 ppb Au, and an assay of the feldspar porphyry returned <2 ppb Au (Davies and Smith, 1988).
