one of the largest and most productive deposits of complex ores in Canada, located in the southeastern part of the province of British Columbia, near the city of Kimberley. It yields approximately one-fourth of the lead mined in Canada and 10 percent of the zinc, as well as silver, cadmium, bismuth, arsenic, and indium. The mines were opened in 1892; since 1900 they have been worked by Cominco, Ltd., a company controlled by English capital. The ores are processed at a concentrating plant in Kimberley and from there are sent to a refinery at Trail.
