Been diving into copper production data lately and there's some interesting stuff happening in the mining sector. Here's what caught my attention about where the world's copper actually comes from.

Chile remains the largest producer of copper in the world by a significant margin. They pulled in 5.3 million metric tons last year, which represents roughly 23 percent of total global output. That's a pretty dominant position when you think about it. Major players like BHP, Rio Tinto, Anglo American, and Glencore all have substantial operations there. What's wild is that BHP's Escondida mine alone - the single largest copper mine globally - churned out around 1.13 million MT just from BHP's 57.5 percent stake. Rio Tinto holds 30 percent of that operation.

But here's where it gets interesting. The Democratic Republic of Congo has been climbing fast. They hit 3.3 million metric tons in 2024, up noticeably from 2.93 million the year before. Ivanhoe Mines' Kamoa-Kakula project ramped up Phase 3 production in August and is already showing momentum. That joint venture with Zijin Mining produced over 437,000 MT.

Peru came in third with 2.6 million metric tons, though that was actually down from 2023. Freeport McMoRan's Cerro Verde saw a 3.7 percent decline due to maintenance and lower ore volumes. Meanwhile, China's mining output sits at 1.8 million metric tons, but here's the kicker - their refined copper production absolutely dominates at 12 million metric tons annually. That's more than 44 percent of global refined supply, six times what Chile produces.

Indonesia moved up to fifth place with 1.1 million metric tons, passing both the United States and Russia. Freeport McMoRan's Grasberg complex is the workhorse there. The US held steady at 1.1 million metric tons as well, with Arizona responsible for about 70 percent of domestic production. Russia produced 930,000 metric tons, boosted by the Udokan mine ramping up in Siberia.

Australia, Kazakhstan, and Mexico round out the top ten. Australia hit 800,000 metric tons with BHP's Olympic Dam mine posting a ten-year high. Kazakhstan produced 740,000 metric tons and actually entered the top ten this year, while Mexico came in at 700,000 metric tons.

Globally, we're looking at roughly 23 million metric tons of total copper production. What's worth watching is that China holds the world's largest copper reserves at 190 million metric tons, with Australia and Peru tied for second at 100 million metric tons each. The largest producer of copper in the world right now faces some supply concerns - aging mines without enough new capacity coming online, yet demand from the energy transition keeps climbing. That's creating an interesting dynamic for the market ahead.
