Supporting continued mine production since 1969


Since 1969, KCB and its predecessors have provided geotechnical, hydrological and hydrogeological services for this copper-molybdenum mining complex located 50 km southwest of Kamloops, British Columbia. The Highland Valley Copper mine, owned 100% by Teck Resources, is one of the world’s largest copper mining and milling operations.

KCB, in partnership with other consultants, has been involved in the design, construction and decommission planning of the mine’s tailings storage facilities, including two tailings dams. The 170-m high (as of 2017) L-L tailings dam is an earthdam constructed mainly of hydraulically placed cycloned sand. The 90-m high (as of 2017) H-H Dam is constructed of earth and rockfill. Together they retain the 9.6 km-long, 2 km-wide tailings impoundment, with a current storage capacity of 1.3 billion tonnes. Both dams are centreline dams with an impervious glacial till core, following the pioneering design of Earle Klohn, one of the founders of KCB.

In addition to the tailings storage facilities, KCB recently designed the foundation for a multiplate overpass for the passage of mining trucks from the main pit to the rock dump facility near the mill. During construction, KCB’s services included quality assurance testing for the backfilling of the foundation fill and for the structural backfill zone.
