Since 1969, Klohn Crippen and its predecessors have provided geotechnical, hydrological and hydrogeological services for the large copper-molybdenum mining complex located near Logan Lake, British Columbia. The complex, now operating under the partnership of Highland Valley Copper (HVC) formed by Teck Cominco, BHP Billiton, and Highmont mining companies, is one of the world’s largest copper mining and milling operations with a daily milling rate of 136,000 tonnes. Klohn Crippen, in partnership with other consultants, has been involved in the design, construction and decommissioning of the mine’s tailings storage facilities including two Bethlehem, Highmont and Highland Valley tailings impoundments. The range of our services encompasses: investigation, design, construction monitoring and decommissioning of various tailings dams, including the implementation of permanent spillways.
