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

Notes:

1. Metal contained in concentrate.

2. We include 100% of production from our Quebrada Blanca and Carmen de Andacollo mines in our production volumes, even though we own 76.5% (90% effective April 2018) and 90%, respectively, of these operations, because we fully consolidate their results in our financial statements. We include 22.5% of production from Antamina, representing our proportionate equity interest in Antamina. We include 21.3% of production from Fort Hills, representing our estimated proportionate equity interest in Fort Hills.

3. Copper production includes cathode production at Quebrada Blanca and Carmen de Andacollo.
