South 32 has cut its full-year production guidance for several commodities after heavy rainfall at its South African thermal coal operations and an underground fire at its Cannington mine in Western Australia.
The diversified miner expects unit production cost at Cannington's silver, lead and zinc mine to rise to $US155 a tonne, up from its previous guidance of $US141, following disruption of operations in early April.
The company reported a decline in March quarter production for several commodities and also said it is pursuing exploration opportunities for base metals in four countries, after signing two separate joint venture agreements.
