Teck Cominco Mining Company / Stock



The Quebrada Blanca Mine is located in northern Chile, approximately 170 kilometres southeast of the port city of Iquique, and 1,500 kilometres north of Santiago. The mine is located at an elevation of more than 4,000 metres.

Teck Cominco has a 76.5% interest in the Quebrada Blanca Mine, with the remaining interests being held by Inversiones Mineras S.A., a Chilean private company, (13.5%) and Empresa Nacional de Minera, a Chilean government entity, (10%). Teck Cominco acquired its interest in Quebrada Blanca through the acquisition of Aur Resources in August 2007.

The Quebrada Blanca mine is an open-pit truck-and-shovel operation, employing standard drilling and blasting techniques. The mine processing facilities produce copper cathode by utilizing crushing, agglomerating, stacking, heap leaching, dump leaching and solvent extraction and electrowinning (SX-EW) processes.

The copper cathode produced is trucked to the Chilean port of Iquique for shipment to purchasers.
