Rio Tinto has temporarily shut its Amrun and Andoom bauxite mines in Queensland after Cyclone Narelle hit northeast Australia.

These two mines produce about 30 million tonnes of bauxite each year, which is used to make aluminium.

The company said it has activated its cyclone response plans. It stated that the priority is the safety of workers and the protection of site operations. Rio Tinto added, “We will continue to closely monitor the situation and take all necessary precautions.”

Cyclone Narelle brought strong winds, heavy rainfall, and power outages across parts of northeast Australia. Authorities advised residents to stay indoors and prepare for possible damage. Weather conditions have made it difficult to continue normal mining operations.

The shutdown was first reported earlier in the day. Following the news, Rio Tinto’s share price fell by up to 4 per cent, reaching AUD 145.36 (USD 102.99). This is the lowest level for the stock since January 13.

The Amrun and Andoom mines are part of Rio Tinto’s larger bauxite operations in Australia. These sites play an important role in supplying raw material for aluminium production. Any disruption at these mines may have an impact on supply chains if it continues for an extended period.

For now, the closure is described as temporary. The company has not given a timeline for when operations will restart. This will depend on weather conditions and site safety assessments after the cyclone passes.

Rio Tinto said it will continue to review the situation and provide updates as needed.
