Largest Copper Mine in Europe: Output Data and Gold Mines

The largest copper mine in Europe is usually named as Rudna in Poland, one of three underground mines run by KGHM Polska Miedź. KGHM calls Rudna one of the largest deep copper ore mines in the world, with capacity of about 12 million tonnes of ore a year. Together the three Polish mines produced 401,100 tonnes of copper in concentrate in 2025. The answer changes with the measure, though: the biggest single-mine copper figure in the 2025 filings used here is Čukaru Peki in Serbia, and the most ore is milled at Aitik in Sweden.

This page sets those measures side by side using 2025 company reports, then does the same for gold mines in Europe. It also shows who owns each mine, for readers who searched for the best copper mines to invest in, and gives you a calculator to test any ore body against today’s prices.

Largest copper mine in Europe: three answers

“Largest” can mean a group’s copper output, one mine’s copper output or the ore it mills. A different operation leads on each test, so check which one your question needs.

• Largest group of mines by copper output: KGHM’s Polish mines. Lubin, Rudna and Polkowice-Sieroszowice extracted 30.3 million tonnes of ore in 2025 and yielded 401,100 tonnes of copper in concentrate, per the KGHM results presentation.
• Largest published single-mine copper output: Čukaru Peki, Serbia. Zijin Mining reports 172,300 tonnes of copper and 5.177 tonnes of gold for 2025.
• Most ore milled at one copper mine in this comparison: Aitik, Sweden. Boliden milled 39.2 million tonnes in 2025, more than KGHM’s three Polish mines extracted together, yet that ore gave only 51,077 tonnes of copper.

Why not simply rank Rudna first on output? KGHM’s results presentation reports copper for the Polish division as a whole, not mine by mine. KGHM also describes its Polish operations as one large deposit worked through separate mining areas, and Polkowice-Sieroszowice lists a similar capacity of about 12 million tonnes of ore a year. So Rudna’s title rests on its long reputation and its scale, not on a 2025 copper figure for the mine alone. For a wider table of producers, see our guide to the main copper mines in Europe by production.

Europe’s copper mines compared by output

The table lists operations with a 2025 copper figure in a company report we opened, ranked by copper produced. It covers mines in Europe outside Russia. USGS estimates Russia mined 1.3 million tonnes of copper in 2025, but that is a national figure with no European split, so Russian mines are not ranked here. Mines in Turkey are also left out.

Chart

tonnes, 2025, as reported by each owner; selected operations outside Russia

Figures are as each owner reports them, so the bases differ slightly: KGHM and Boliden give copper in concentrate, Zijin gives mine production (Bor on a 100% basis) and Atalaya gives copper production. The Neves-Corvo figure includes months before Boliden bought the mine from Lundin Mining on 16 April 2025.

The national picture agrees with the table. USGS estimates Poland mined 410,000 tonnes of copper in 2025 out of a world total of 23 million tonnes, or about 1.8%, and puts Poland’s reserves at 33 million tonnes. Serbia has no separate line in that USGS table, even though its two big mines together produced more than 295,000 tonnes.

Rudna and the KGHM mines in Poland

Rudna lies north of the town of Polkowice in Lower Silesia. Building began in 1969 and mining started in 1974. Output reached 11.3 million tonnes of ore by 1983, and recoverable resources stood at 315 million tonnes at the end of 2025, grading 1.96% copper and 62 grams of silver per tonne. Grade here means the share of metal in the rock; “recoverable resources” is KGHM’s own measure of what is available to the mine.

The depth is what sets the mine apart. The orebody at Rudna lies 844 to 1,250 metres down, and the shafts reach 940 to 1,348 metres, according to KGHM. Miners use the room-and-pillar method, leaving columns of rock to hold up the roof, with blasting to break the ore.

Polkowice-Sieroszowice holds 315 million tonnes of recoverable ore at about 2.67% copper. Lubin, the oldest mine in the belt, holds around 318 million tonnes at a lower 1.23%. Across all its Polish deposits, KGHM counts over 30 million tonnes of copper in geological resources at an average 1.64%. Geological resources are a wider count than recoverable resources, so the two sets of numbers should not be added together.

KGHM’s next step is the Głogów Głęboki-Przemysłowy area, which it describes as the largest deep mining project in Europe. That claim is the company’s own. The geology is a sediment-hosted copper system, the Kupferschiefer, covered in the USGS sediment-hosted copper deposit model. For how such ore bodies compare with other types, read where copper is found on Earth.

Čukaru Peki and Bor: Europe’s main challenger

Zijin’s two Serbian operations together produced 296,000 tonnes of copper and 9.1 tonnes of gold in 2025, and Zijin describes itself as the second-largest copper producer in Europe. Its 2026 guidance for the pair is 296,000 tonnes of copper and 8.1 tonnes of gold. Expansion is aimed at 450,000 tonnes a year, which Zijin says would make it Europe’s largest copper miner. That is a company target, not a result.

Čukaru Peki is an underground mine with an Upper Zone in production and a Lower Zone under construction. Zijin reports resources of 22.3 million tonnes of contained copper at 0.84%. Bor is held 63% by Zijin and combines open-pit and underground mining; its resources contain 112.7 million tonnes of copper at 0.46%, plus 388 tonnes of gold. On that metal-in-the-ground measure, Bor is well above the 30 million tonnes KGHM counts in Poland, though the two companies report on different definitions, so treat it as a rough comparison.

Aitik, Riotinto, Neves-Corvo and other copper mines

Aitik (Sweden). This large open pit in Norrbotten shows what a low-grade, high-volume mine looks like. Head grade, the metal content of ore entering the mill, was 0.15% copper in 2025, down from 0.17%, and copper output fell from 59,818 to 51,077 tonnes. Boliden expects grades to improve in the second half of 2026.

Riotinto (Spain). Atalaya Mining processed 16.6 million tonnes at 0.39% copper in 2025 for 51,139 tonnes of copper, and says its plant is the largest processing facility in the Iberian Pyrite Belt.

Neves-Corvo (Portugal). The opposite of Aitik: about 2.26 million tonnes of copper ore at 1.7% gave 30,665 tonnes, with a large zinc stream alongside.

Kevitsa (Finland). Boliden milled 10.2 million tonnes at 0.25% copper here for 22,728 tonnes of copper, plus nickel and 14,767 ounces of gold.

Las Cruces (Spain). First Quantum Minerals agreed in December 2025 to sell the mine to a company controlled by funds managed by Resource Capital Funds, and that release expected closing in the first half of 2026, a date now past, so check the current owner. It is not ranked here because that release is about the sale, not 2025 output.

Why ore tonnage and copper output tell different stories

Dividing reported copper by ore tonnes gives a quick measure of how much metal each tonne yields. KGHM’s Polish mines gave about 13 kilograms of copper per tonne of ore in 2025 and Neves-Corvo about 14. Riotinto gave about 3, Kevitsa about 2 and Aitik about 1.3. That is a tenfold gap between mines that all count as major European copper operations.

A consultant comparing a new prospect with these mines should choose the right peer. A thin, rich, deep ore body should be compared with Rudna or Neves-Corvo, where the cost is in the shafts and the ventilation. A big, low-grade, near-surface body should be compared with Aitik or Riotinto, where the cost is in moving rock. Those per-tonne figures are our own arithmetic from the reports, and they ignore the value of silver, gold, zinc and nickel by-products.

Gold mines in Europe: output from the same filings

Among European mines that publish a gold figure, Kittilä in Finnish Lapland leads, with 217,379 ounces in 2025. Several of the next largest are also copper mines, which is why the two metals belong in one comparison. Note that Olimpiada, often listed as a European gold mine, is in Krasnoyarsk Krai, Russia, which is in Siberia, so it does not belong on a Europe list. USGS puts Russia at about 310 tonnes of gold in 2025, without a Europe split.

Best copper mines to invest in: what you can actually buy

You generally cannot buy a share in a single mine such as Rudna. You buy the company that owns it, and then you carry all its other assets and risks too. So there is no neutral ranking of the “best” mine for an investor. The useful question is which listed owner gives what exposure. This table gives facts only.

Our comparison of the largest copper producers puts these names in a global context. The page you are reading is for information only and is not investment advice.

What to check before relying on a mine’s numbers

1. Basis. Is the figure copper in concentrate, payable copper or refined metal? KGHM’s 570,900 tonnes of electrolytic copper includes metal from purchased materials, so it is not mine output.
2. Ownership share. Bor’s figure is on a 100% basis, while Zijin holds 63%.
3. Grade trend. Aitik’s copper fell by about 15% in 2025 largely on grade and milled tonnes.
4. By-products. Silver at KGHM, and gold at Čukaru Peki and Chelopech, change the economics.
5. Prices. Trading Economics showed copper at US$6.27 per pound on 5 November 2026 and gold at US$4,119 per ounce the same day, on contracts for difference that track benchmarks. US$6.27 per pound is about US$13,820 per tonne, the unit the calculator below uses. US$6.27 per pound is about US$13,820 per tonne, the unit the calculator below uses.

This calculator turns tonnes, grades and recoveries into gross metal value, less a mining and processing cost. Enter a mine from the tables above or your own prospect. Recovery is the share of metal the plant actually captures. The result is a screening number; it leaves out smelter charges, royalties, tax and capital cost.

Environmental issues at Europe’s large copper and gold mines

Scale brings large waste volumes. USGS notes that tailings from the Rudna, Polkowice and Lubin mines go to a common tailings pond. Tailings are the fine waste left after the metal is taken out. At Aitik, Boliden’s 2025 report describes a completed dam project, and capital spending on it is reported separately. Aitik’s waste production also rose sharply in 2025, to 63.5 million tonnes from 35.8 million. Those are the kinds of figures a consultant should request and track, along with water balance and closure provisions.

Emissions are the other pressure. ICMM, the mining industry council, describes Boliden’s electric trolley lines for haul trucks at Aitik as one way to cut greenhouse gases from transport at a large open pit.

How exploration teams screen ground near these districts

Any new deposit still has to be proven by drilling. Satellite imagery helps earlier in the process, by mapping alteration minerals, structures and surface disturbance across a licence before drilling. It works best on exposed ground and is of little direct use for a deep, covered ore body like Rudna’s. Farmonaut offers satellite-based mineral detection for this early screening, and results are exploration targets that come ahead of any resource estimate. You can request a quote or contact the team with a licence boundary.

Frequently asked questions

What is the largest copper mine in Europe?

Rudna in Poland is the mine most often named. It is one of three KGHM mines that together gave 401,100 tonnes of copper in concentrate in 2025. The largest single-mine figure in the 2025 filings used here is Čukaru Peki in Serbia, at 172,300 tonnes.

Is Kiruna a copper mine?

No. Kiruna in Sweden is run by LKAB, which sells iron ore and related products. The large Swedish copper mine is Aitik, owned by Boliden.

Which country mines the most copper in Europe?

Among the European countries USGS lists, Russia is highest at an estimated 1.3 million tonnes in 2025, though USGS gives no European split. Poland follows at 410,000 tonnes. Serbia has no separate line, but Zijin’s two mines there produced about 296,000 tonnes.

How deep is the Rudna mine?

KGHM says the orebody lies 844 to 1,250 metres below surface in the Rudna deposit, and the shafts are 940 to 1,348 metres deep.

What is the largest gold mine in Europe?

Among European mines publishing a gold figure, Kittilä in Finland leads with 217,379 ounces in 2025. Turkish and Russian mines are outside this comparison.

Is the Olimpiada gold mine in Europe?

No. Olimpiada is in Krasnoyarsk Krai in Siberia, so it should not be counted among Europe’s gold mines.

Who owns Neves-Corvo now?

Boliden, which bought the mine and Zinkgruvan in Sweden from Lundin Mining on 16 April 2025.

What are the best copper mines to invest in?

No source can give a neutral answer, and this page gives no recommendation. Investors buy listed owners rather than single mines, so compare each owner’s grade trend, ownership share, by-products and country risk using its filings.

Will Zijin overtake KGHM in Europe?

Zijin targets 450,000 tonnes a year from Serbia and says that would make it Europe’s largest copper miner. KGHM’s Polish mines gave 401,100 tonnes in 2025. Zijin’s 2026 guidance is unchanged at 296,000 tonnes, so the target is still ahead.

Can a satellite find copper at Rudna’s depth?

Not directly. Satellites read the surface, and Rudna’s ore lies more than 800 metres down under cover. Imagery is more useful where altered rock is exposed.
