Antofagasta’s $2B profit and Chile copper woes: production and asset risks for engineers

30 Second Briefing
Antofagasta has cut its 2026 copper production guidance to 625,000–655,000 tonnes, down from 650,000–700,000 tonnes, after heavy rain and snowfall in July forced a full shutdown of the Los Pelambres operation in Chile’s Coquimbo Region under a government “state of catastrophe”. First-half pretax profit still jumped 72% year-on-year to $2 billion, with EBITDA up 27% to $2.84 billion and operating cash flow up 53% to $2.77 billion, driven by a 36% copper price rise and 46% gold price gain. The company reports no major infrastructure damage but must repair pipeline platforms and water-management systems, while net debt has increased to about $4 billion and 2026 guidance cuts at both Antofagasta and Codelco sharpen concerns over Chile’s ageing copper assets.
Technical Brief
- July shutdown at Los Pelambres followed a government-declared “state of catastrophe” in Coquimbo Region.
- Antofagasta’s London-listed shares fell 5.3% on the day, to 3,814 pence.
- Company market capitalisation sits around £37.7 billion (about $50 billion).
- Adjusted earnings reached $847 million ($0.86/share), 15% above BMO’s forecast.
- Net debt increased to roughly $4 billion, from $2.8 billion at end‑2025.
- Interim dividend declared at $0.30/share, aligned with a 35% payout ratio, ~1.1% yield.
- Codelco has trimmed 2026 guidance to ~1.34 Mt Cu, down from ~1.37 Mt and well below the earlier 1.7 Mt target.
Our Take
Antofagasta’s plan to lift copper output by 30% by 2030, flagged at the World Mining Congress, sits awkwardly against a 5% cut to current-year production guidance, signalling that near-term operational or water constraints in Chile may force a steeper ramp-up profile later in the decade.
Codelco’s trimmed 2026 guidance to 1.34 Mt, well below the earlier 1.7 Mt target, combined with Antofagasta’s strong copper- and gold‑price leverage (36% and 46% price gains in the period), underlines how private Chilean producers with growth projects could gain pricing and negotiating power in a structurally tighter domestic supply setting.
The decision to commit $900 million to extend the Zaldívar copper mine using treated wastewater, alongside rising net debt to $4 billion, suggests Antofagasta is willing to carry a heavier balance sheet to secure long‑life, lower‑risk Chilean copper exposure at a time when our database shows copper remains one of the most frequently covered critical minerals in mining news.
