CSR has revealed it will use Rio Tinto's planned sale of its $US5 billion ($5.01bn) aluminium asset portfolio to review its 25 per cent interest in the Tomago aluminium smelter in NSW, which could result in the building materials group quitting the stake.
In his first public comments on the issue since Rio announced plans in October to tip its aluminium assets into a new business unit call Pacific Aluminium, CSR chief executive Rob Sindel said the group could sell the Tomago take to help fund a major acquisition of a new building materials business.
