BHP (ASX: BHP) shares fell on Thursday despite the mining giant reporting record annual iron ore production. Investors focused instead on weaker copper production guidance and an eight-hour strike at the company’s Port Hedland operations.
BHP shares closed 2.34% lower at A$59.14 on 16 July 2026. The decline showed that record iron ore output was not enough to ease concerns about the company’s copper outlook.
Record Iron Ore Production Fails to Lift BHP Shares
BHP produced a record 264.7 million tonnes of iron ore during the financial year ended 30 June 2026.
The strong result reflected reliable performance across the company’s Western Australian iron ore operations. BHP said it had delivered record iron ore production while producing around two million tonnes of copper for the second consecutive year.
Iron ore remains one of BHP’s largest sources of earnings. However, investors are increasingly focused on copper because the metal plays an important role in electricity networks, renewable energy, electric vehicles, and data centres.
This helps explain why the market paid more attention to the weaker copper forecast than the record iron ore result.
Why the Copper Warning Matters
BHP produced approximately 1.95 million tonnes of copper in FY26. However, the company expects production to fall to between 1.65 million and 1.80 million tonnes in FY27.
At the midpoint of that range, copper output would be approximately 12% lower than the FY26 result.
The expected decline is mainly linked to lower ore grades at the Escondida mine in Chile.
Ore grade measures the amount of copper contained in the rock being mined. When grades fall, a mining company normally needs to process more material to produce the same amount of copper. This can reduce production and increase costs.
The warning is important because copper has become a major part of BHP’s earnings and growth plans. Copper contributed 51% of the group’s underlying earnings before interest, tax, depreciation and amortisation during the first half of FY26.
Investors will therefore be watching whether lower grades at Escondida are a temporary problem or a longer-term challenge.
Will the Port Hedland Strike Disrupt Shipments?
Around 200 workers at BHP’s Port Hedland operations also stopped work for eight hours on Thursday.
The strike followed unsuccessful negotiations over wages and employment conditions. It was one of the most significant industrial actions to affect the region’s resources sector in many years.
However, the strike did not cause an immediate disruption to port operations. ABC reported that BHP remained on track to load seven ships by 10 pm on Thursday.
This means the initial eight-hour stoppage is unlikely to have a major effect on BHP’s earnings or annual shipments.
The risk would increase if workers begin longer or repeated strikes. Port Hedland is a critical export hub for BHP’s Pilbara iron ore operations, so extended disruption could delay shipments and sales.
What Should Investors Watch Next?
BHP’s record iron ore result shows that its largest operations remain strong. However, the share-price fall suggests investors are looking beyond current production records.
The main issues to watch are copper production at Escondida, mining costs, copper prices and any further strike action at Port Hedland.
For now, weaker copper guidance appears to be the bigger concern. The Port Hedland strike remains a risk, but the first stoppage did not cause a confirmed interruption to operations.
