Thanks Tweety.

I don't know much about mining but would be glad for any clarification:
1. How do the projected cash costs of $21/t compare to other miners?
2. Slide 18 has got two statements about Xstrata. The RFP option and SEEP JV. I understand Xstrata have an interest in Roseby copper project and that they need to exercise the option before 30 June 2012 or else they lose their rights? Can anyone put in more plain language what must/should/could happen in regards to Xstrata?

Thanks.
