Redundancies, page-66

In the preliminary project financials, the copper price and fx converted to from memory $3.68lb
Using current copper prices and fx it works out to be A$3.30 lb or 90% of the figure they used in the prelim financials
So not a disaster on the copper front (cobalt prices though are way way below what they used)

So WM puts great store in the prelim financials, he even quoted figures from it in his court dealings with HC

So price should not be an issue.
