Top 20 Countries With Largest Copper Reserves in the World [2023 Updated]

Within this comprehensive piece, we’ll delve into an examination of the top 20 Countries With Largest Copper Reserves in the World. If you’re inclined to bypass the intricate specifics and directly uncover the most significant copper riches, keep reading.

These countries are actively working towards enhancing their mining capacities to boost their exports and capitalize on their copper riches. However, the significance of copper reserves goes beyond geological and industrial considerations; it carries profound financial implications and strategic importance for these nations.

The value associated with copper mining activities is primarily driven by the metal’s wide-ranging applications in electronics, construction, and renewable energy sectors. The ever-increasing demand for copper, driven by technological progress and global infrastructure development, further underscores its significance.

The financial impact of copper reserves manifests through various avenues. Revenues generated from copper mining, processing, and exports play a pivotal role in strengthening the economic positions of these nations. Copper contributes significantly to their Gross Domestic Product (GDP) and boosts public sector revenues. For instance, in the year 2022, Chile, which boasts the largest copper reserves globally, witnessed its mining sector contributing over 14% to its GDP. Notably, copper constituted a substantial portion of the country’s export earnings.

As per The International Copper Study Group’s (ICSG) 2022 World Copper Factbook, Chile emerged as a dominant player in the copper industry in 2021. The nation accounted for nearly one-third of the world’s total copper mine production, boasting an impressive output of 5.6 million metric tons. This accomplishment can be attributed to Chile’s extensive mineral reserves and robust mining infrastructure. To explore which countries are effectively leveraging their copper reserves, take a look at our coverage of the Top 15 Copper Producing Countries for a more insightful perspective.

In the latter half of the previous decade, Peru’s copper mining sector experienced significant growth starting from 2015. This period marked a noteworthy increase in the country’s copper production, resulting in Peru contributing a commendable 10.8% to global copper mine production by 2021.

Despite Peru’s strides in identifying new copper reserves, the country’s concession system poses challenges for new investments in the mining industry. It’s also worth noting that the impressive growth in copper production in Chile and Peru has shifted the global copper supply landscape. This shift comes as the United States and European nations aim to diversify their mineral imports, moving away from heavy reliance on mainland China.

Copper Mining Capacity Worldwide

In the year 2022, the Escondida mine situated in Chile claims the top spot for the highest copper mining capacity globally, boasting an impressive 1,510 thousand metric tons. This substantial capacity is primarily owned by BHP Group Limited (NYSE:BHP), with a 57.5% stake, and Rio Tinto Group (NYSE:RIO), holding 30%. The Escondida mine is characterized as a copper porphyry deposit.

In close pursuit, Indonesia’s Grasberg copper mine, owned by Freeport-McMoRan Inc (NYSE:FCX), holds a noteworthy copper mining capacity of 800 thousand metric tons.

Notably, the Morenci mine, which also ranks as the fourth-largest mine based on capacity, along with the Safford mines, both located in Arizona and owned by Freeport-McMoRan Inc (NYSE:FCX), experienced a remarkable surge in copper production during 2022.

Among the copper mines in the United States, a standout performance in terms of increased throughput was observed at The Bingham Canyon Mine, owned by Rio Tinto Group (NYSE:RIO) in 2022. This notable improvement in throughput can be attributed to higher recovery rates achieved during the year.

Furthermore, in the landscape of copper mining, the Antamania copper mine in Chile, operated by BHP Group Limited (NYSE:BHP), secures its place as the seventh-largest copper mine by throughput capacity, boasting a capacity of 450 thousand metric tons.

Worldwide Copper Reserves Declining? Duration of Copper Reserves?

According to data from the ICSG (International Copper Study Group), the capacity for copper mining is projected to reach 31.2 million tons by the year 2026, reflecting the increasing demand for refined copper. Notably, the consumption of copper surged to 25.3 million metric tons in 2021, a significant jump from the 500,000 tons recorded in 1990, and this upward trajectory shows no signs of slowing down.

Key players like The Bingham Canyon Mine, under the ownership of the Rio Tinto Group (NYSE:RIO), the Safford mines in Arizona owned by Freeport-McMoRan Inc (NYSE:FCX), and the Escondida Mine, with substantial ownership by BHP Group Limited (NYSE:BHP), significantly contribute to the overall mining capacity.

The remarkable compound annual growth rate of 3.3% in copper production raises an important question: will copper reserves dwindle in the near future? A thorough analysis of data from the United States Geological Survey (USGS) spanning back to 1960 reveals a consistent trend of maintaining an average of 40 years’ worth of copper reserves at any given time.

Furthermore, the global supply of copper isn’t solely reliant on original ore reserves. Supplementary strategies such as copper recycling, innovative technologies, and ongoing exploration efforts have played a crucial role in sustaining the availability of copper.

While the modern technological landscape has led to heightened demand for copper extracted from ores, the expansion of known reserves has managed to keep pace. Over the two decades from 2000 to 2021, despite extracting 373 million tons of copper, the reserves experienced a net growth of 447 million tons, leading to the current total of 890,000 million metric tons, as indicated by USGS data.

A study conducted by USGS in 2015 revealed that globally identified copper reserves amount to 2.1 billion tons, while untapped resources are estimated at 3.5 billion tons. This expansion in reserves reflects the outcomes of persistent exploration efforts, advancements in mining technology, and the evolving economics of mining operations.

However, beyond the measured and unmeasured copper reserves, the challenges in copper production are concerning. Due to limited mining capacities and production shortages, there is a worrisome scenario of a potential 20% deficit in copper supply by 2035, a stark contrast to the mere 2% shortfall observed in 2021.

The Approach We Follow

The provision of government estimates regarding minerals is an annual endeavor undertaken by USGS (United States Geological Survey) through its Mineral Commodity Summaries. To compile our list of countries with the largest copper reserves worldwide, we referred to the 2023 edition of this publication. Specifically, we delved into the copper section to extract the relevant findings. Alongside identifying these nations, we also scrutinized recent developments and trends within the copper sector, drawing insights from the same USGS publication.
