Metals and commodities trading firm Glencore PLC is aiming to cut net debt by about $20 billion. The plan includes suspending operations at two copper mines for 18 months in a bid to lower operating costs. The Katanga and Mopani mines are located in the Democratic Republic of the Congo and Zambia, respectively, and their suspensions will remove about 400,000 tonnes of copper cathode from the market, which are “substantial reductions” by Glencore to copper output.
