Despite these challenges, Rio Tinto remains focused on its core business of mining iron ore in remote northwest Australia, with production reaching 84.1 million metric tons during the quarter, up 1% year-on-year and 6% from the previous quarter. Shipments from the Australian operations, primarily destined for Chinese steel mills, also increased by 1% year-on-year to 84.5 million tons. The company maintained its annual shipment estimate for the region and highlighted that productivity improvements are offsetting declining reserves in older mines.
