Anderson SERVICE DE LA Toronto, Ontario DOCUMENTAT NTECHNIQUE • 13 - A0 U 1974 . May, 1974. Date: No GM: SELCO MINING CORPORATION LIMITED GEOPHYSICAL REPORT GRASSET LAKE AREA INTRODUCTION During the period January to April, 1974, magnetic and electromagn._`_ic surveys were completed on 37 grids in Grasset Lake area. This report describes the results on 30 of those grids LOCATION &ACCESS The claim groups are located in the townships of Bapst, Ste. Helene, Subercase, Grasset, La Gauchetiere, and Daniel. Access to the souther part of the area is by winter roads sponsored by the Quebec Department of Natural Resources, which extend west from New Hosco, and northwest from mile 80 on Highway 61. Northern claim groups are best reached by float or ski-equipped aircraft from Matagami. GEOLOGY The geology of the area west of longitude 78°00' has been mapped at one inch to one mile and described by Remick (1969), and the reader is referred to this report for details. At the extreme eastern edge of the area, in Daniel Township, felsic ana intermediate volcanics which 2 • host the massive sulphide deposits of the Matagami camp either terminate or form the western closure of an anticline about the Bell River Complex (Sharpe, 1968). With the exception of the Allard River area towards Matagami, most of the geology of the area is only known in a general fashion, due to very limited outcrop exposure.

UNIVERSITY. APRIL 1913. A,O.DUPRESNE. During the summer of 1912, Dr J.A.Bancroft, Associate Professor of Geology at McGill University ,was instructed by the Quebec Department of Mines to make a geological reconnais- sance of the District ^lorth of Transcontinental Railway in North Western Quebec. Having been fortunate enough to accompany Dr Bancroft as assistant ,1 submit,in this paper,the results of a geological examination of the 80untry surrounding Gull & Olga Lakes,of which I made an independent investigation. LOCATION. The district is situated on the James Bay side of the Height of Land, about mid-way between the Transcontinental and James Bay,one hundred and ten miles east of the Quebec-Ontario boundry. The accompanying key-map shows the relative position of the area. It lies between 76 fi 30' and 77- 30f West Longitude and 49-A50*North Latitude. The district has an area of about five hundred square miles. MEANS OP ACCESS, a) The district is best reached by way of The Grand JLJ^ Trunk Pacific,starting from Cochrane -Bast and going to the A Natagagan River or the Bell River. The rest of the journey can be made by^ going down either of these rivers to Ma t*a garni A Lake which is situated just west of the district under conside­ rs ration and is connected with Olga Lake by a River five miles long? This route is certainly very easy and diligent canoemen, leaving the railroad at either point; could reach the discharge of - 2 - of Bell River in four days.

NTS 32F13 TECHNICAL REPORT Jean-Pierre Cloutier, B.Sc. March 01, 2001 (Revised August 23, 2001) MRN-GÉOINFORMATION 2002 GM 59670 p,~ -/37-D/À SUMMARY The Allard River property of Caribgold Resources Inc is situated in the prolific Matagami Mining Camp of Northwestern Quebec. The property is owns 100% by Caribgold Resources Inc subject to a 2% NSR royalty. It is located at 18 km WNW from the town of Matagami and consists of 119 mineral claims covering 1,847 hectares. The property occurs in the south central part of Daniel township and the southwest area of NTS map 32F13. REGIONAL GEOLOGICAL SETTING Matagami Mining Camp is located in the northern part of the Abitibi Greenstone Belt of the Abitibi sub-province. The most outstanding geological feature of the area is the Bell River Complex. It consists of a large layered mafic intrusion of oval shape measuring 70 km EW by 15 km NS. The Complex is at the core of the Galinée Anticline. This anticline is a major fold structure. The fold has a steep vertical axial plan striking WNW to EW with its axis gently plunging to the west. The Bell River Complex is injected locally but mostly in its eastern part by massive granodioritic intrusions of the Olga pluton. The western end of the Bell River Complex is surmounted by a lower succession of rhyolitic volcanics of the Watson Group and a upper succession of basaltic volcanics of the Wabassee Group.

  • Fracture Analysis of a Volcanogenic Massive Sulfide-Related
    ©2007 Society of Economic Geologists, Inc. Economic Geology, v. 102, pp. 667–690 Fracture Analysis of a Volcanogenic Massive Sulfide-Related Hydrothermal Cracking Zone, Upper Bell River Complex, Matagami, Quebec: Application of Permeability Tensor Theory S. E. IOANNOU†,* AND E. T. C. SPOONER Department of Geology, University of Toronto, 22 Russell Street, Toronto, Ontario, Canada M5S 3B1 Abstract Located in the Matagami mining district of the Abitibi greenstone belt, Quebec, the Bell River Complex is a >5-km-thick tholeiitic layered gabbro and/or anorthosite body (2724.6 +2.5/-1.9 MaU-Pb), which likely acted as the heat source that drove hydrothermal convection and volcanogenic massive sulfide (VMS) hydrothermal mineralization in the area. Abundant fractures and veins crosscutting the western lobe of the Bell River Complex formed over a range of temperatures from 250° to 700°C. The 250° to 400°C assemblage, quartz-epidote ± sericite ± chlorite ± pla- gioclase, is the most widespread and occurs as orthogonal, anastomosing, and random vein sets. Vein densities average between 15 and 25 veins per m2, locally reaching as high as 40 to 60 veins per m2. These veins, typi- cally 1 to 3 mm wide, are interpreted to represent thermal cracking associated with hydrothermal fluid miner- alization in the district. Furthermore, they crosscut earlier higher temperature pyroxene-plagioclase (>600°C) and magnetite-rich (300°–600°C) veins (1–10 mm wide; densities commonly ~0–5 veins per m2). Detailed field measurements of quartz-epidote vein geometries coupled with permeability tensor theory have produced a first-order approximation of the maximum model permeability structure (veins unfilled) of the hydrothermal cracking zone.
