Copper has become a hot topic due to its role in the green energy transition and its necessity for urbanization. However, the lack of incoming supply in the long term has experts concerned.
Due to its importance in construction, energy transmission and new technologies, copper is a critical metal needed to power the future of our society. However, mined supply has not kept pace with demand, with few new operations coming online, and older mines facing decreasing grades and lower outputs.
The term “peak copper” was coined because some experts believe that copper reserves may be diminishing. According to the US Geological Survey (USGS), more than 700 million metric tons of copper have been mined throughout history, and current economic global copper reserves stand at 980 million metric tons.
Nearly all of that mined copper is still in circulation, as the red metal’s recycling rate is higher than that of any other engineering metal, but it is still not enough to keep up with escalating demand. As a result, it’s prudent to know the top copper reserves by country, especially when considering investing in the copper mining industry.
Reserve data for this article was sourced from the USGS’s 2025 Mineral Commodity Summary and supplemented with datasets from Mining Data Online (MDO) and the UN Comtrade Database.
Top 5 copper reserves by country
The countries with the largest copper reserves are Chile, Australia, Peru, the Democratic Republic of Congo (DRC) and Russia. These five countries hold more than 55 percent of the world’s total copper reserves and will be critical to a world with soaring demand for copper.
Read on to learn about these copper kingpins.
1. Chile
Copper reserves: 190 million metric tons
Chile holds the largest copper reserves globally at 190 million metric tons, nearly as much as Australia and Peru hold combined. Additionally, Chile is also the world’s top copper producer, with its 5.3 million metric tons of copper in 2024 representing nearly a quarter of global output.
The mining industry is essential to the Chilean economy, making up more than 50 percent of the country’s exports and contributing US$40 billion of its GDP in 2023. Copper alone accounting for more than US$29 billion of that total.
Due to the sheer quantity of copper in the country, it should come as no surprise that Chile is home to the world’s largest copper mine, Escondida. According to MDO, Escondida produced 927,000 metric tons of copper in concentrate in 2024 and sits atop proven and probable copper reserves of 37.62 million metric tons. The mine is a 57.5/30/12.5 joint venture between BHP (ASX:BHP,NYSE:BHP,LSE:BHP), Rio Tinto (ASX:RIO,NYSE:RIO,LSE:RIO) and Japan’s JECO.
2. Australia
Copper reserves: 100 million metric tons
Australian copper reserves are pegged at 100 million metric tons, tying it for the second largest country by copper reserves. The resource industry is an essential sector in Australia, contributing AU$385 billion during the 2024/2025 fiscal year. Of that, copper was the sixth largest contributor with AU$13.2 billion, a AU$1.8 billion increase over 2023/2024.
While Australia hosts significant copper reserves, it lags the other countries on the list with similarly sized reserves in terms of production at 800,000 metric tons in 2024. More than a quarter of that came from BHP’s Olympic Dam mine in South Australia, which produced 216,000 metric tons of copper cathode. The polymetallic mine contains substantial proven and probable copper reserves totaling 10.68 million metric tons.
Another significant operation in Australia is Newmont’s (TSX:NGT,NYSE:NEM,ASX:NEM) Cadia Valley mine, which hosts probable reserves of 3.1 million metric tons of contained copper. Cadia Valley produced 87,000 metric tons of copper in concentrate in 2024.
2. Peru
Copper reserves: 100 million metric tons
Copper reserves in Peru stand at 100 million metric tons, tying it with Australia for the second largest copper country. Much like its neighbor Chile, copper is an essential part of Peru’s economy, accounting for 49 percent of the value of its US$47.7 billion in mining exports.
Peru is home to some of the world’s biggest mining operations, and produced 2.6 million metric tons of copper last year. Two mines accounted for a third of the country’s total output.
The top producer in the country is the Cerro Verde Complex, a 55/21/19.6 venture with Freeport-McMoRan (NYSE:FCX), Sumitomo Metal Mining (TSE:5713) and Minas Buenaventura (NYSE:BVN). Cerro Verde hosts hosts proven and probable reserves of 11.45 million metric tons of copper and produced 949 million pounds of copper metal in concentrate in 2024.
Not to be outdone, the second highest is Antamina, a 33.75/33.75/22.5/10 joint venture between BHP, Glencore (LSE:GLEN,OTC Pink:GLCNF), Teck Resources (TSX:TECK.B,TSX:TECK.A,NYSE:TECK) and Mitsubishi (TSE:8058). Last year, output at the mine fell just short of Cerro Verde’s at 941 million pounds of copper in concentrate. Antamina hosts a proven and probable reserve of 4.53 million metric tons of contained copper.
The mine with the largest copper reserves in Peru is Southern Copper’s (NYSE:SCCO) Toquepala mine, home to 13.79 million metric tons of copper in proven and probable reserves. The mine produced 496 million pounds of copper in concentrate last year.
4. Democratic Republic of Congo
Copper reserves: 80 million metric tons
Copper reserves in the Democratic Republic of Congo stood at 80 million metric tons in 2024, making it the fourth largest country by copper reserves. The DRC’s economic copper reserves have seen a staggering rise in recent years, climbing from an estimated 19 million metric tons in 2019.
The mining sector has been critical to GDP growth in the DRC, with copper being the largest contributor. World Bank reports that the extraction sector has outpaced other segments of the DRC’s economy, increasing 12.8 percent in 2024, while non-mining sectors grew by only 3.2 percent.
According to data from the United Nations, in 2023 the DRC exported US$17 billion in refined copper and unwrought alloys, a large jump from US$7.34 billion in 2019. The country’s copper ore exports contributed US$2.16 billion in 2023, nearly double the US$1.11 billion four years prior.
Among the contributing factors in the rise in mining and export activity has been the development of the Lobito Corridor, which connects mineral-rich regions in Zambia, the DRC and Angola to the port at Lobito in Angola.
This link allows greater access for large-scale operations like Ivanhoe Mines (TSX:IVN) and Zijin Mining’s (HKEX:2899,SHA:601899) Kamoa-Kakula complex in the Southern DRC. One of the largest copper operations in the world, Kamoa-Kakula hosts a probable reserve of 17.69 million metric tons of contained copper and produced 964 million pounds of copper in concentrate in 2024.
4. Russia
Copper reserves: 80 million metric tons
Russia’s copper reserves are estimated to be 80 million metric tons, tying it with the DRC. While commodities are important to the Russian economy, contributing US$417 billion in 2024, the metals sector represented 15 percent of that total at US$60 billion.
Russia has been under significant sanctions since it invaded Ukraine in February 2022. According to the UN Comtrade Database, Russia’s copper exports from in 2021 were valued at US$5.98 billion.
In 2024, Russia produced 930,000 metric tons of copper, an increase from the 890,000 metric tons produced in 2023. Among the main contributing factors was a ramp-up in production at Udokan Copper’s Udokan mine in Siberia, which was expected to produce 135,000 metric tons in 2024 and, according to the mine’s website, hosts a JORC-compliant copper resource of 26.7 million metric tons.
