According to the annual report published by the Chamber of Mines in Democratic Republic of Congo, besides low commodity prices, erratic electricity supply reduced copper output in the country.
Copper production dropped 3% to 995 805 tons in 2015. Output in the fourth quarter slumped 12% from the previous year, it said.
In the annual report, the Chamber says the shortage of electricity in Congo grew to 950 megawatts in 2015, from 542 megawatts the previous year.
A picture that emerges is that, even if the commodity prices were to rebound, mining companies would not be able to increase productivity to capitalise.
