The Norbeau mine property is a past producing gold mine located seven kilometers northeast of the town of Chibougamau, Quebec on the south shore of Lake Bourbeau in map sheet 32G/16 in the central part of the Abitibi volcano sedimentary belt within the Superior province of the Canadian Shield which extends from the Timmins area in the west to the Chibougamau area in the east. The Abitibi camp has been explored for precious and base metal deposits for the last one hundred years and several deposits within the camp have been developed. The number of the deposits and the economic value of each one makes the Abitibi camp one of Canada’s most favorable mining camps.
The Norbeau mine has a history of gold production as well as substantial reserves yet to be mined from several undeveloped levels. Between1965 to 1969 the Norbeau mine produced 419,029 tons grading 13.77 g/t (0.38 oz/t) from eight levels spaced 150 feet apart and a total of 5,101 kilograms of gold and 632 kilograms of silver were mined. The mine shaft was sunk to just below the undeveloped 9th and 10th levels.
The host rocks are gabbro sill and diorite. Five orogenic auriferous quartz veins associated with shear zones and fault structures were discovered and mined between 1964 and 1969 including the main vein, # 4, the Sharp vein, and the Mann vein. Gold and silver mineralization is usually associated with disseminated chalcopyrite, arsenopyrite and pyrite minerals.
The main vein (No. 1 vein) has produced about 80% of the ore extracted from the Norbeau mine from a productive maximum length of 260 meters. Its maximum width is 4.6 meters (average of 1.5 meters).
Vein # 1 still accounts for proven reserves of 110,000 tons at 7.6 g/t Au while the inferred reserves of the Norbeau mine are evaluated at 745,000 tons at 6.17 g/t Au (Lavergne, 1985 and Whiteway, 1986). This reserve estimate was not calculated or classified under the current specifications as outlined in the National Instrument 43-101.
Gold potential on the remaining part of the property may be considerably more extensive than current information suggests. The latest geological and geophysical surveys completed on the property area revealed significant information indicating good potential for new target areas as well as locating the extension for the existing veins. These areas have never been tested by modern geological and geophysical techniques.
All data and the results of the previous drilling are available and can be ordered from the Department of the Natural Resources of Quebec as well as the drill plans showing the location of all drill holes. Over 40,000 feet of core is reported and presently stored at the mine core shack. The Norbeau maps and files are also reported to be stored at the mine site.
The property is readily accessible and all facilities essential for large scale production are close at hand allowing for a low cost operation.
