BHP Group (LSE:BHP) reported a 19% decline in copper production for the first quarter of its 2027 financial year, reflecting lower ore grades, scheduled maintenance and operational disruptions at several mining sites.
The mining group produced 400,700 metric tonnes of copper during the three months ended 30 September 2026, compared with 493,600 tonnes in the corresponding period last year.
Production was affected by lower planned concentrator feed grades at the Escondida and Spence operations in Chile.
In Australia, severe weather and a conveyor belt failure disrupted operations at the Carrapateena copper mine, contributing to the overall reduction in output.
Despite the decline, BHP maintained its full-year copper production guidance of between 1.65 million and 1.8 million tonnes for FY27.
Iron ore production increased to 66.5 million metric tonnes during the quarter, compared with 64.1 million tonnes a year earlier, representing growth of approximately 3.7%.
The increase was supported by performance across BHP’s Western Australia Iron Ore operations, including its mining, rail and port infrastructure.
The company reported quarterly production records at both its mines and port facilities despite significant planned maintenance during the period.
BHP also reaffirmed its full-year iron ore production guidance of between 260 million and 272 million tonnes.
Commodity pricing trends varied across the group’s principal products.
BHP reported a 53% year-on-year increase in its average realised copper price to $7.01 per pound, providing additional revenue support despite lower production volumes.
Meanwhile, the average realised iron ore price declined by 9% to $76.27 per wet metric tonne.
The contrasting price movements highlight differences in market conditions affecting the company’s copper and iron ore businesses.
BHP also addressed workplace safety following fatal incidents at its Escondida and Peak Downs operations.
The company said investigations into both incidents were underway and reiterated that safety remained a priority.
For investors, the quarterly update presents a combination of lower copper volumes, higher realised copper prices and increased iron ore production.
The rise in copper prices may help offset some of the financial impact of reduced output, although the overall effect on earnings will depend on production costs and other operating factors.
Maintaining full-year guidance indicates that BHP has not revised its annual production expectations following the first-quarter disruptions.
Looking ahead, investors will be monitoring copper production recovery, operational conditions at Escondida, Spence and Carrapateena, and the group’s progress towards its FY27 output targets.
Changes in realised commodity prices and the findings of the ongoing safety investigations will also remain relevant to the company’s operational and financial performance.
