Shares of Rio Tinto Group (ASX:RIO) fell past 2% in recent Tuesday trade after Reuters reported Monday that the company's shareholder and activist fund Palliser Capital demanded that the company make a counterbid for Canadian resource firm Teck Resources.
In an Oct. 17 letter to the company's board, Palliser also urged the miner to unify its London and Sydney listings and split its base metals business.
The company and Palliser did not immediately respond to MT Newswires' request for comment.
