MELBOURNE May 10 U.S. private equity firm Carlyle Group has submitted a bid for Anglo-Australian miner Rio Tinto's 80 percent stake in the Northparkes copper mine in Australia, Dow Jones reported on Friday, citing a person familiar with the bid.
Macquarie, which is advising Rio Tinto on the sale, declined to comment. A Carlyle executive and Rio Tinto spokesmen were not immediately available for comment.
Northparkes is one of several assets that Rio Tinto plans to sell as it looks to pare $5 billion in costs and focus on its best assets to help protect its single-A credit rating in a weakened commodities market.
Carlyle is the second private equity firm to be linked to the Northparkes stake after it was earlier reported that KKR & Co was looking to bid.
However, KKR is no longer in the running, two sources told Reuters.
