Granduc Copper Mine Concentrator

 mine, production

This was the site of the Concentrator, surface facilities, and housing for the Granduc Copper Mine. Initial site work started in the fall of 1966 and construction went swiftly during the short summers of 1967 and 1968. By that fall all surface facilities were covered and construction did not stop until completion in November, 1970. The entrance for the Tide Lake Tunnel which provided access between here and the Leduc Mine Site was located here as well.

The remote location, the type of terrain and the bad weather, made supply of equipment and construction materials difficult. Handling was minimized by loading trailers in Vancouver, barging them to Stewart, then hauling them to Tide Lake over a 32-mile road, all of which was improved or built by the company at a cost of $10 million.

In the course of construction, a fully-equipped marine terminal for bringing in supplies and shipping out concentrates was also built at Stewart. Development of the mine began after the tunnel was completed and went on until the mill was ready to operate.
