Antofagasta plc Announces the Construction of the Centinela Second Concentrator Project Antofagasta plc announced that after an extensive review, the construction of the Centinela Second Concentrator Project has been approved. Critical path works will begin immediately with full construction expected to commence after definitive project finance documents have been executed during First Quarter 2024. Growth: Centinela Second Concentrator to produce an additional 170,000 tonnes of copper equivalent tonnes per annum, comprising of 144,000 tonnes of copper production, 130,000 ounces of gold production and 3,500 tonnes of molybdenum production, with a 36-year mine life based on Centinela's substantial ore reserve of two billion tonnes. · Lower net cash costs:Moving to first quartile C1 cost of production at Centinela through an increased focus on concentrator capacity that incorporates modern technologies, increased by-products and greater economies of scale. Net cash costs in the Centinela district are expected to be in the first quartile of the industry cost curve following the expansion. Capital investment:Project cost of $4.4 billion, including a new 95ktpd concentrator plant incorporating high pressure grinding rolls ("HPGRs") to reduce energy consumption, the expansion of the existing raw seawater pumping and transport system, a new tailings storage facility, capacity growth in energy and other input supply infrastructure, the expansion of outbound logistics networks such as the concentrate transport system and critical port infrastructure, additional loading equipment, autonomous hauling equipment and a truck-shop for the mine expansion at Esperanza Sur. Also included are camps, and ancillary civil infrastructure, which have been designed to fully integrate into the existing Centinela operation, to avoid any redundancy. This updated and approved capital cost estimate (previously $3.7 billion - announced in August 2022) is based on advanced detailed engineering and includes escalation for inflation during construction, a stronger local currency estimate, updates to local labour regulations and additional contingency provisions. The phasing of the project's capex is expected to be weighted towards2025, with similar expenditures in adjacent years. · Mining plan:The second concentrator will source ore initially from the recently opened Esperanza Sur pit and later from the Encuentro pit. The sulphide ore in the Encuentro pit lies under the Encuentro Oxides reserves, which are expected to be depleted by 2026. Fully exposing the sulphide ore in the optimal sequence required to initiate feed to the second concentrator from the Encuentro Pit is expected to require separate investments in infrastructure, mining equipment and mine development activities, which will materially commence half-way through the construction phase of the second concentrator and will span a period of 3-4 years. The combined investment in mine development and sustaining capital for the expansion of the Encuentro pit is estimated to be approximately $1 billion. This expansion in mining activities will further enable Centinela to achieve the development potential of its extensive mineral resource base. · Financing: Project to be financed by Centinela through a combination of direct funding from Centinela's shareholders (Antofagasta plc and Marubeni Corporation, representing approximately 40% of total funding), and project finance provided by lenders. Definitive project finance documents are expected to be executed during First Quarter 2024. · Water infrastructure: Detailed terms and conditions have been substantially completed for the option to provide water for Centinela's current and future operations by a third party acquiring the existing water supply system and building the new water pipeline expansion. The planned outsourcing of the water supply will only proceed if it improves the net present value of the project, with closure of this process scheduled to be made alongside the execution of definitive project finance documents during First Quarter 2024. If it goes ahead as planned, an estimated amount of $600 million in cash will be received for the divestment of the existing water infrastructure and the project cost will reduce by approximately $400 million, considering that the investment required to expand the existing water system to supply the Second Concentrator will be undertaken by a third party. · Project permitting: The Centinela Second Concentrator Project has all the relevant permits approved by the authorities in Chile for the project to proceed into the construction phase. · Timeline: Three-year construction schedule, with critical path works commencing immediately. First production is expected in 2027. Tillkännagivande • Dec 12
