Antofagasta’s shares jumped over 10% after global copper futures climbed 7% to $6.34 per pound, marking a near 48% year-on-year increase. Investors reacted positively to the sharp rally that reflects ongoing supply constraints and strong demand from electrification trends. The stock’s performance underscores the company’s leverage to commodity cycles, positioning it as a beneficiary of sustained upside in base metals markets.

The miner reported a 9% quarter-on-quarter increase in copper output, with Q4 production reaching 177,000 tonnes. Full-year copper output totaled 653,700 tonnes, in line with upper guidance ranges and up from 638,200 tonnes in the prior year. Gold production also held firm, contributing to revenue diversification. Unit costs remained competitive, reinforcing Antofagasta’s first-quartile position in the global cost curve and bolstering free cash flow generation.

Antofagasta is advancing its Centinela expansion project, which is expected to add approximately 370 million pounds of annual copper capacity and reduce operating costs through enhanced throughput and processing efficiencies. This growth, scheduled to come online by late 2025, should support record profitability and cash flow in the 2025–2026 period. Management forecasts that higher realized copper and gold prices, combined with these capacity gains, will drive shareholder returns through dividends and share buybacks.
