1518 GMT [Dow Jones] Rio Tinto PLC's (RTP) $469M investment to develop the US-based Kennecott Eagle nickel and copper mine was expected and reaffirms the company's belief that long-term demand recovery is underway, says Rebecca O'Dwyer of Investec. Adds: "It's Rio Tinto's first major nickel development. After 18 months where they have been very tight with capital expenditure, this is a sign that they are perhaps more confident about the recovery." Investec has a buy rating and 4750p target price.
