Corporación Nacional del Cobre de Chile (Codelco) has secured approval from the regional environmental regulator to extend the operational life of its Radomiro Tomic mine until 2030.
The approval from the Antofagasta Region Environmental Assessment Commission allows the company to invest $882m in the expansion of the project.
The open pit mine in the Antofagasta region was initially planned to be closed in 2022.
However, the company plans to incorporate new mining resources to extend the mine life for another seven years.
Codelco executive president Octavio Araneda said: “This is very good news for Codelco and for Chile.
“The continuity of Radomiro Tomic’s operations and its sustainable extension in the coming years is part of our plan to continue providing resources to the State, and thus collaborate with the development and progress of our country and of those who need it most.”
