Extended lockdowns hit copper production

Peruvian copper mine Antamina, owned by BHP (NYSE: BHP; LSE: BHP) and Glencore (LSE: GLEN), has reported 210 positive cases of coronavirus and said the date to restart operations is still uncertain.

One of the largest copper-zinc mines in the world, Antamina produced 101 million tonnes of copper in 2019.

The announcement on April 27 comes after six workers at Fortuna Silver Mines' (NYSE: FSM) Caylloma operation in southern Peru also tested positive for COVID-19.

Freeport McMoRan's (NYSE: FCX) El Abra copper mine in Chile also announced it would scale back copper processing by 40%, as global prices for the red metal plunge amid the coronavirus pandemic.

The mine, located in the province of El Loa in northern Chile, is one of two copper mines operated by Freeport in South America. The world's largest publicly traded copper producer said on April 24 that it would cut its 2020 costs by 18%, or $1.3 billion, as prices for the red metal plunge.

Copper giant Codelco has also been hit by delays in upgrades and expansion projects caused by measures to stop the spread of the novel coronavirus.

Anglo American's (LSE: AAL) Los Bronces copper mine in Chile, outside the capital Santiago, saw output tumble 25% to 68,700 tonnes, battered primarily by a worsening drought in the region.
