Glencore PLC has revised its 2022 production forecasts, cutting copper output by 40,000 tons and zinc output by 100,000 tons due to geotechnical issues and labor shortages. Despite these setbacks, the company expects trading profits to exceed the top end of its guidance, bolstered by a strong marketing division. Additionally, Glencore has increased its output guidance for nickel and ferrochrome and reported a 16% rise in thermal coal production, reflecting a strategic pivot amidst ongoing market volatility.
