Latest Developments
Antofagasta has completed a review of the project schedule and costs for an expansion of its flagship Los Pelambres copper mine, and on April 21 reported a revised capital cost estimate of $2.2-billion.
This is a 30% increase from the previous estimate of $1.7-billion and is mainly owing to the impact of Covid-19 on costs and the construction schedule, as well as generation inflation, including increased input prices, wages, labour incentives and logistics costs.
Antofagasta in early 2021 raised the capital expenditure estimate from an original $1.3-billion to $1.7-billion, owing to revised marine works that were needed to enable the future expansion of the desalination plant.
At the end of March, the project was about 73% complete.
Key Contracts, Suppliers and Consultants
None stated.
