Abstract

The Pierre Beauchemin gold mine is located in the Flavrian pluton 15 km northwest of Rouyn-Noranda. In 1955, Eldrich Mines Ltd. sunk a 325 m shaft and developed 7 levels of drifts; reserves defined at that time included 589 670 tonnes grading 6.9 g/t Au. The Eldrich mine operated from 1955 to 1962, and shipped a total of 651 045 tonnes of flux-type ore (65 to 67% Si02) grading 4.78 g/t Au (a total of 3.1 tonnes of gold). to the Noranda smelter. In 1987, Cambior Inc. became the owner and operator of the newly named Pierre Beauchemin gold mine and adjacent claims. Workings are presently being developed to a depth of approximately 1900 feet (11 levels). The mine began production in August 1988, and has produced an average of 1050 tonnes/day. Present reserves are 1.2 Mt grading 5.6 g/t Au.
