"in situ" gold price has been averaging roughly $75 for producers with 43-101 compliant reserves...casey research should wake up and realize that many companies are'nt even messing with "proven and probable" recently... inferred and measured/indicated seem to be good enough in this market...

the problem is, $75 represents companies from the bottom of the scale (like kry) at $7 per oz. to many companies over $400oz...mines in canada are commanding the highest premiums while mines in venezuela, the "stans" and much of africa are'nt worth as much for obvious reasons...low cash costs are very important but it seems like folks have put more value in government stability and business environment.
