Antofagasta Copper Production Surges in Q1 2025 on Chilean Mine Gains

Antofagasta

Strong Growth at Los Pelambres and Centinela Drives Higher Output

Antofagasta’s copper production surged in the first quarter of 2025, driven by strong performance at its Chilean mines. The London-listed miner produced 154,700 tonnes of copper, up 20% year-on-year. Copper sales rose 47.1% to 170,200 tonnes. This growth reflects improved processing rates and higher ore grades at its flagship operations.

At the Los Pelambres mine, copper output jumped 26.4% year-on-year to 69,900 tonnes, supported by reduced maintenance disruptions. Meanwhile, Centinela’s copper production rose 23.6% to 55,600 tonnes, as concentrate volumes climbed 56.1% thanks to better copper grades. However, Centinela’s cathode production fell 10% to 19,800 tonnes due to shifting production priorities.

Full-Year Copper Outlook Stays Bullish

Antofagasta reaffirmed its 2025 copper production guidance at 660,000–700,000 tonnes amid strong market fundamentals. Copper output at Antucoya rose 3.1% to 20,200 tonnes, while Zaldivar fell 5.3% to 9,000 tonnes in the quarter. The company also reported molybdenum production up 14.8% to 3,100 tonnes, with Centinela contributing an impressive 60% rise.

Copper remains vital for global electrification and energy security, according to CEO Ivan Arriagada. As a result, Antofagasta expects long-term demand growth and plans to meet it through ongoing project expansions.

The Metalnomist Commentary

Antofagasta’s quarterly copper boost reinforces Chile’s role as a global copper hub. As demand for electrification metals grows, production agility at major mines will remain a critical advantage.
