Anglo American’s first-quarter production rose 3% year on year despite some operations running at 95% capacity because of covid-19 disruptions, it said on Thursday.

Copper production climbed 9% to 160,000 tonnes in the quarter from 147,000 tonnes in the same period last year, but down from 168,000 tonnes in the previous three months. Diamond output slipped 7% year-on-year, partly due to excessive rainfall in southern Africa and a covid-19-related shutdown in Canada.
