The table below shows our share of production of our major commodities for the last five years.

⁽¹⁾ We include 100% of the production and sales from Quebrada Blanca and Carmen de Andacollo mines in our production and sales volumes, even though we own 90% of these operations, because we fully consolidate their results in our financial statements. Our ownership in Quebrada Blanca is expected to be 60% upon closing of our transaction with Sumitomo Metal Mining Co., Ltd. and Sumitomo Corporation, and production and sales will continue to be reported on a 100% basis. We include 22.5% and 21.31% of production and sales from Antamina and Fort Hills, respectively, representing our proportionate ownership interest in these operations. Copper production includes cathode production at Quebrada Blanca. Zinc contained in concentrate production includes co-product zinc production from our copper business unit.

⁽²⁾ Energy (bitumen) results for the year ended December 31, 2018 are included from June 1, 2018.

⁽³⁾ Production estimates for 2019 represent the midpoint of our production guidance range.
