The strong performance from the marketing division came during a period marked by sharp commodity-price swings and disruption from the Middle East conflict. Chief executive Gary Nagle said Glencore expected to report the strong half-year earnings alongside a robust production performance across its mining operations. Glencore left its full-year copper guidance unchanged at 810,000-870,000 tonnes despite completing the sale of the Kidd mine in June. The energy coal forecast was raised by one million tonnes to 96-101 million tonnes following stronger Australian production. Steelmaking coal guidance was narrowed to 30-32 million tonnes from 30-34 million tonnes.
