Floating Factory Completes Nine-Day, 2,500-Mile Voyage To Canadian Arctic A factory barge as big as a football field recently completed a 2,500-mile voyage from the St. Lawrence River to a small island in the Canadian Arctic. It arrived nine days ahead of schedule — at Little Cornwallis Island, 600 miles above the Arc- tic Circle, to help exploit the most northerly base metal mine in the world. The $40-million floating fac- tory was drawn by tugboats through iceberg-infested waters during the short "Arctic ship- ping window" which sometimes lasts no more than six weeks. The huge factory barge, called the Arvik 11, left Three Rivers, near Montreal, on July 24. It will be part of the Polaris mine op- erated by Vancouver-based Com- inco Ltd., which is slated to start lead and zinc concentrate produc- tion early next year. While the barge base was built by Davie Shipbuilding, Lauzon, Quebec, Comstock and Dominion Bridge constructed the ore proc- essing plant onboard the vessel. Bechtel Canada is responsible for the surface facilities for the project. 3. The BUTTERWORTH® MP Machine. Cleans Hard-to-reach Areas From Any Angle.
