Glencore PLC (LSE:GLEN) has maintained its production forecast for the current year even though most of its mining operations saw modestly lower output in their latest quarter.
Cobalt saw the biggest drop at 18%, but copper, zinc, nickel and silver were also down with gold flat.
Coking coal was up sharply as Glencore saw the first contribution by the assets acquired from Teck Resources.
Gary Nagle, chief executive, noted production improvements at African Copper Antapaccay, Kazzinc, Murrin Murrin and Australian energy coal.
