Can anyone tell me what the value of 4N ,5N and 6N HPA is?  Im trying to get a value on ORT for HPA only.  Called IR this morning and they gave me a 50,000 per tonne figure for 4N but he wasn't sure what higher purity would fetch.  I looked at my notes from a year ago and quotes were as high as 400,000 per tonne.  Thats a pretty big gap, have prices really droppe that much or was someone at ORT over optimistic?.


Do we have any more clarity on the HPA figures?
