pog is out of sync with costs, page-27

It makes sense BH! that companies would look to a resource of at least 2 million ounces and that would need to be decent average grades and in a politically stable country and preferably not in an earthquake zone! Start up costs would be huge and would need to be amortised over a significant resource. I would only go for a junior with a resource of 2 million plus ounces. Indeed mine has 5 million and good grades. Anyone got an opinion on what grades are needed at what levels?
