Not sure about the term "exaggerated" but if you call the Kitco and LME Cu prices that, then that is what I used and always use.

I don't use those sites but if they are spot prices then I believe they are exaggerated for these type of valuations.

As for recovery rates I have used the data in the reports.

Which recovery rate did you use. PWC show 3 options 60/70 and 80%

By the way PWC have calculated between US$6000 and US$7000 up to the year 2015. Maybe an average of $6500.
