05:30 PM EST, 11/17/2025 (MT Newswires) -- Rio Tinto (RIO) said Monday it will reduce production at its Yarwun alumina refinery in Gladstone by 40% starting in October 2026 to extend the operation's life to 2035.

The tailings facility is expected to hit capacity in 2031, and the cut will trim annual output by about 1.2 million tonnes and impact around 180 roles, with redeployment planned, according to a statement.

Rio Tinto said customer supply and other operations will not be affected.
