Commercial production at the Mouska gold mine project, 25 miles east of Rouyn-Noranda, Que., of Cambior (TSE) is expected to begin in June, 1991. In announcing a production decision for the property, Cambior said the mine will operate at an initial annual rate of 187,000 tons and turn out 31,000 oz. gold per year.
The company, based in Val d’Or, Que., completed an exploration program in May. Proven and probable reserves were calculated to be 850,000 tons grading 0.18 oz. gold per ton to a depth of 1,100 ft. The deposit remains open laterally and at depth.
The Mouska deposit contains four narrow veins dipping from 60 degrees to 80 degrees . Shrinkage and small- diameter longhole mining methods have been selected by the company. The ore will be transported by truck to the Yvan Vezina mill 50 miles (by regular roads) northwest of the mine project.
Cambior estimates capital expenditures of about $6 million will be required to bring Mouska to the production stage, after allowing for preproduction revenue. Preproduction work will include underground infrastructure development and stope preparation.
Operating costs for the mine will average an estimated $310 per oz. The mine at full production will employ 97 full-time workers, the company said.
Cambior, which will turn out about 220,000 oz. gold this year, has interests in seven mines in production or under development.
