BHP Group BHP released production details for the quarter ended Sep 30, 2021 and affirmed its previously announced production and cost guidance for fiscal 2022. Total iron ore production dipped 4% to 63 Mt (million tons) in the quarter due to higher planned maintenance and temporary rail labor shortages related to COVID-19 related border restrictions. The company reported declines in quarterly output for copper, metallurgical coal and nickel, while petroleum and energy coal were up year over year. Last week, the company's peer, Rio Tinto plc RIO, reported a 4% drop in iron ore production to 83.3 Mt in the July-September quarter citing heritage management, brownfield mine replacement tie-ins and project completion delays.
