Those with Google Earth, change the position to view UTM (Universal Transverse Mercator) in the setting options.
Go to Jorge Lopehandia's website and on the first page you will see environmental sat maps which show Tesoro claims with a yellow mountain highlighted. Jorge says the gold is there. Check out the other maps, Amarillo Sur covers that area. As for proof how much gold is at that location, my understanding is that through environmental and drill records that is Pascua. Of course all unvarified or MWR would be above $20 right now.
