About the company
Antofagasta plc prepares its accounts under the UK Companies Act 2006 and publishes through the London Stock Exchange, yet its operations are in Chile. The half-year report for the six months to 30 June 2026 says the group is organized into two business divisions based on their products: Mining and Transport.
The Mining division is reported mine by mine: Los Pelambres, Centinela, Antucoya and Zaldívar, plus exploration and evaluation and corporate items. The Transport division, reported as FCAB, provides rail and road cargo transport. The report names Metalinvest Establishment as the group's immediate parent and the E. Abaroa Foundation, in which members of the Luksic family are interested, as ultimate parent.
Two divisions, with partial holdings drawn dotted
Solid lines follow the group's management reporting. The Mining division holds each mine, the exploration and evaluation segment and the mining corporate centre, Antofagasta Minerals S.A., while Transport stands alone. A solid line does not mean full ownership: the group's earlier payments-to-governments report describes Los Pelambres, Centinela and Antucoya as subsidiaries with non-controlling interests.
Dotted lines mark partial interests. The group holds 50% of Minera Zaldívar, a joint venture with Barrick Gold Corporation, 18.94% of Buenaventura, an associate, and 30% of Antofagasta Terminal Internacional, which operates a port concession. Twin Metals Minnesota, a wholly owned US project on hold during litigation, is drawn under exploration and evaluation, where its costs are reported.
How this structure supports the business
A flat list of four mines would read as four equal subsidiaries, yet Zaldívar is a 50% joint venture and the group's Peruvian and port holdings are minority stakes. Separating the divisions the group manages from the dotted interests it only shares shows what Antofagasta controls, what it partly owns, and why Transport sits apart from Mining.
Interesting facts
- Antofagasta's 2026 half-year report names seven reportable segments, including Exploration and evaluation, Corporate and other items, and the Transport division.
- The group accounts for its 18.94% of Buenaventura as an associate because of its rights to propose directors to the Peruvian company's board.
- Corporate and other items, including the mining corporate centre Antofagasta Minerals S.A., are reported within the Mining division.
