SANTIAGO – Chile's Chuquicamata underground copper mine is due to start operations in the middle of this year, the State copper miner Codelco's chairman said on Wednesday.

Chairman Juan Benavides said the start-up will be "a fundamental step and milestone in this structural overhaul" of Codelco.

Codelco, which produces nearly 10% of the world’s copper, announced a $5.550-billion investment to convert Chuquicamata, its second-largest resource, from an opencast mine into an underground facility last year.

The plans for Chuquicamata are part of a 10-year, $39-billion overhaul of the state miner's key operations as it seeks to maintain production despite rapidly falling ore grades at its deposits.

Finance Minister Felipe Larrain confirmed in the same news conference on Wednesday that the government would pay out the remaining $400-million of $1-billion capitalisation for Codelco's overhaul that was announced last June.

"This is a show of the confidence we have in the company and in the importance of these resources for Codelco to be able to complete its structural reform program," Larrain said.

Codelco's Chuquicamata and nearby Radomiro Tomic mines produced 653 000 tonnes of the company's total 1.8-million tonnes of output last year, a third of Chile's total production.
