Chilean miner Antofagasta revealed on Wednesday that the expansion project at its Los Pelambres operation in the home country would cost $1.7 billion, up from the original $1.3 billion, due mainly to revised marine works and value of a desalination plant extension.

Construction of the project resumed in August, after a four-month halt triggered by the covid-19 pandemic.

A detailed review of the schedule and costs, including those associated with the realized and ongoing restrictions linked to the global pandemic followed. The assessment also considered changes to the marine works to enable an expansion of the desalination plant.
