bhp say no to olympic dam

Just watching Trading Day on Foxtel and BHP said that the development would now be on the back burner for a couple of years . The problem with Olympic Dam is the ore is to deep and to bring it to the surface would be so expensive. One possible option is a gigantic open pit at a capex of $20 billion but no comment further to date with that option .
Now does that put Rex Minerals in a good position with its definite open pit option at Hillside . BHP and its options must be be a better result for Rex Minerals with its future open pit mine and low cost extraction. Still need the initial capital to get it going but a twist of fate I would say for the future of copper in South Australia .
