Top 10 Copper Mines by Production
Copper is the metal the entire energy transition is short, and these mines are the supply side of the argument. Figures are approximate annual copper output and move with grades — but this list is where the world's electrification physically comes from.
| # | Operation | Approx. output |
|---|---|---|
| 1 | Escondida — Chile | ~1.2 Mt/yr |
| 2 | Grasberg — Indonesia | ~750–800 kt/yr |
| 3 | Collahuasi — Chile | ~550–600 kt/yr |
| 4 | Kamoa-Kakula — DR Congo | ~550–600 kt/yr and climbing |
| 5 | Cerro Verde — Peru | ~450 kt/yr |
| 6 | Morenci — Arizona, USA | ~400 kt/yr |
| 7 | El Teniente — Chile | ~400 kt/yr |
| 8 | Buenavista del Cobre — Mexico | ~400 kt/yr |
| 9 | Antamina — Peru | ~400 kt/yr Cu + zinc |
| 10 | Oyu Tolgoi — Mongolia | ~350 kt/yr and rising fast |
The rundown
Escondida — Chile
~1.2 Mt/yrThe undisputed heavyweight: in a good year this one mine supplies roughly 5% of world copper.
