<img src='content_image/254364.jpg'>

Notes to five-year production record and 2013 estimate: 

(1) We include 100% of the production and sales from our Highland Valley Copper, Quebrada Blanca and Carmen de Andacollo mines in our production and sales volumes, even though we own 97.5%, 76.5% and 90%, respectively, of these operations, because we fully consolidate their results in our financial statements. We include 22.5% of production and sales from Antamina, representing our proportionate equity interest in Antamina. 

(2) Coal production in 2008 includes our 40% share of production from the Teck Coal Partnership and 2.345 million tonnes being our indirect share of production from our 19.95% investment in units of Fording. 

(3) Includes pre-commercial production from Carmen de Andacollo prior to September 30, 2010. Production of copper contained in concentrate during the pre-commercial start-up period in the nine months ended September 30, 2010 was 20,700 tonnes. 

(4) Production estimate for 2013 represents the mid-range of our production plan.
