RE:Comparison of gradesHi Mats Interesting story on Barrick's Lumwana mine in Zambia. A clear case of government greed and need for cash destroying the economics of an otherwise viable project. The other implication of course is one less copper mine's output which should help future copper prices due to supply constraint. By how much? Well I'm not prepared to even guess at that question.. Fortunately, our Nevada deposit is in a mining friendly state that really needs the jobs that this project will offer. I'm betting we have political risk to worry about...
