03:52 AM EDT, 03/20/2026 (MT Newswires) -- Rio Tinto (RIO) temporarily shut its Amrun and Andoom bauxite mines in Australia as tropical cyclone Narelle struck far North Queensland with strong winds, heavy rain and power outages, Reuters reported late Thursday.

The company activated cyclone response plans, with the two mines producing about 30 million metric tons of bauxite annually, Reuters said, citing the company.

Rio Tinto is monitoring the situation and will implement necessary safety measures as the cyclone is expected to weaken further as it moves west, the report said.
