Thanks a lot for those amazing maps. When I look at those kinds of maps I always wonder how the geologists figure out where to explore in detail. I know that those guys are optimists by nature, otherwise they would find something else to do while waiting for the big one.

At Herc I wonder about golden gate and how they went about finding that. When looking at the maps, I can't see any reason whatsoever to look there. There are lots of stange anomalities at many locations,but not where they identify GG. Maybe it was so simple that a 4-wheel drive got stuck at that location, spun the wheels down to the bedrock, and there it was?  Anybody with a better explanation ?
