Belleterre Mine

"Belleterre Quebec Mines, Limited, is a subsidiary of Mcintyre Porcupine Mines, Limited. The property is in Guillet township, Quebec, 45 miles due east of Haileybury, Ontario. It is accessible by 72 miles of gravelled road from New Liskeard, Ontario (Fig. 1).Gold production at the property commenced in 1936 and to March 31st, 1945, had exceeded $9,000,000. For the past 3 years the milling rate has averaged 325 tons a day and the gold recovery about $14 a ton.GENERAL GEOLOGYThe rocks of the district consist of Keewatin-like volcanics conformably overlain by Timiskaming-like sediments. Together they form the remnant of an easterly plunging anticline engulfed by granite (Fig. 2). The pregranite intrusives consist of diorite, gabbro, and ultrabasic rocks, occurring as dykes, sills, and irregular stocks. Dykes of porphyry and lamprophyre presumably related to the batholithic intrusive are common in this area. The veins of quartz are also probably derived from the batholithic intrusives. A few dykes of Keweenawan-type diabase have been observed."
