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.
