NEWS RELEASE, 15 NOVEMBER 2018

LOS PELAMBRES EXPANSION APPROVED

60,000 tonnes of additional low-cost copper production

Antofagasta plc announces the approval of the expansion of its subsidiary Minera Los Pelambres ("Los Pelambres"), which is 60% owned by Antofagasta and 40% owned by consortiums led by JX Nippon and Mitsubishi. The expansion will add an average of 60,000 tonnes of copper a year to the mine's production over the first 15 years of operation.

Ivan Arriagada, the CEO of Antofagasta plc, commented: "The expansion of our world-class Los Pelambres mine is an important step forward in the advancement of the Group's organic growth pipeline. The expansion project will add 60,000 tonnes a year of low cost copper production at this long-life operation and will ensure that it remains a first quartile producer for many years to come.

"The project includes the construction of a desalination plant and water pipeline which will also benefit the existing operation in cases of prolonged or severe drought, and for a potential further phase of expansion."

Construction of this $1.3 billion project will start at the beginning of 2019 and first production is expected in the second half of 2021. Throughput at the plant will be increased from the current capacity of 175,000 tonnes of ore per day to an average of 190,000 tonnes of ore per day. The plant expansion includes an additional SAG mill, ball mill and the corresponding flotation circuit with 6 additional cells.

Annual copper production will increase from 40,000 tonnes in the first year at the expanded throughput to 70,000 tonnes towards the end of a 15 year period, as the hardness of the ore increases and the benefit of the higher milling capacity is fully realised. Over the full period production will average approximately 60,000 tonnes.

The capital cost of the project also includes $500 million for a desalination plant and water pipeline. The desalination plant will supply the expansion and a potential further growth phase as well as acting as a back-up for the existing operation in case of extreme dry conditions, were these to materialise.

A subsequent phase of expansion may follow, dependent on the receipt of the necessary environmental and regulatory approvals. This phase will further increase production and also significantly extend the mine life of Los Pelambres as it accesses the operation's substantial undeveloped mineral resources, which are currently some five times larger than its ore reserves.
