KGHM Copper Production Fell in 2025 Despite Stronger Earnings

KGHM

KGHM copper production declined in 2025 after planned maintenance at the Glogow II smelter and refinery in Poland and the first-quarter sale of the McCreedy West mine in Canada. The group’s full-year payable copper output fell 3% on the year to 710,000t.

KGHM copper production was also affected by weaker performance at its North American assets. KGHM International produced 52,200t of payable copper in 2025, down 14% from the previous year, because of the McCreedy West sale, lower recovery rates, and lower copper content in feed.

The weaker KGHM copper production result was partly offset by stronger output from the Sierra Gorda mine in Chile. Payable copper attributable to KGHM’s 55% stake in Sierra Gorda rose 8% on the year to 86,800t, supported by higher copper grades and better recovery rates.

Polish Smelter Maintenance Weighed on Copper Output

KGHM’s Polish operations remained the group’s core production base in 2025. Electrolytic copper production from Polish assets fell 3% on the year to 570,900t because of planned maintenance at Glogow II.

Fourth-quarter electrolytic copper output in Poland rose 1.6% on the year to 149,000t, showing some recovery after maintenance-related disruption. Copper in concentrate from Polish assets totalled 401,100t for the full year, broadly flat compared with 2024.

The results show that KGHM’s Polish copper chain remains operationally stable, but smelter and refinery availability can still influence annual payable production. For European copper supply, this matters because domestic smelting and refining capacity is becoming increasingly strategic as concentrate markets tighten.

Sierra Gorda and Higher Prices Supported Financial Performance

Sierra Gorda delivered a stronger result in 2025 and helped offset weakness elsewhere in the portfolio. KGHM’s attributable copper output from the Chilean mine rose because of better ore grades and recovery rates, while fourth-quarter output increased 6% on the year to 21,900t.

The mine also strengthened KGHM’s by-product profile. Sierra Gorda produced 5mn lb, or 2.27mn kg, of molybdenum in 2025, up 53% from the previous year.

Despite lower copper production, KGHM’s financial performance improved. Group net profit rose 28% on the year to 3.7bn zlotys, while EBITDA increased 22% to 10.3bn zlotys. Stronger copper prices helped support earnings, with the three-month LME copper contract averaging $9,965/t in 2025, up 7% from the previous year.

The Metalnomist Commentary

KGHM’s 2025 results show that copper producers can still improve earnings even when output falls, if prices and asset mix move in their favour. The stronger Sierra Gorda contribution also underlines the value of higher-grade, internationally diversified copper assets.
