The Latin American country has suspended constitutional rights including free movement and assembly as it tries to deal with the fast-spreading virus, which had infected 71 people as of Sunday.

Anglo said the work on the project will be significantly slowed, with only critical areas of the project continuing as normal.

The Quellaveco project, with an expected capital cost of $5 billion (4.08 billion pounds) to $5.3 billion, is expected to start production in 2022.

Anglo expects output of about 300,000 tonnes per year at a cash cost of $1.05 per pound of copper during the first ten years of full production at the project.

Copper accounts for nearly 20% of Anglo's annual revenue.
