MELBOURNE, Jan 23 (Reuters) - Australian diversified miner South32 Ltd (S32.AX) on Monday reported production of key commodities that largely met expectations but noted that shipping snarls had led to an inventory buildup, impacting working capital.
In its quarterly report, South32 met coal, aluminium and copper forecasts and slightly exceeded analyst estimates for manganese ore production, for which it is the world's biggest producer.
"While production was inline, sales were impacted, leading to weaker-than-expected cash generation," said analyst Glyn Lawcock of Barrenjoey in Sydney.
"This impact is most acute in our aluminium value chain in Southern Africa due to ongoing shipping delays."
In manganese ore, South32 reported 1,477 kilotonnes (kt) of production, ahead of an RBC estimate by 7%.
