J. Desrosiers, Lac Dufault Division, Minnova Inc.

Minnova Inc. has five operating divisions thoughout Canada. One of them is Lac Dufault which was established in 1964. Lac Dufault is located 15 km north of Rouyn-Noranda, in what is known as Noranda volcanic centre, in northwestern Quebec. For more than 25 years, Lac Dufault has produced copper, zinc, gold and silver from four different mines: Norbec, Mitten-bach, Corbet and now Ansil. Ansil, officially in production since July 1989, is one of the deepest mines presently in production in Quebec. This high-grade copper, gold, zinc and silver orebody is being mined at a rate of 1200 tonnes per day with a total workforce of 200 employees. Of particular interest are the high mechanization level of the underground mine, technical innovations also underground, and computer applications throughout the division.
