Gold is where you find it.
That’s an old timer joke, and at the same time true. It seems to always end up being found where it “can’t occur”. I saw a youtube video recently where the author bought a sack of sand at Home Depot and panned gold out of it. The Fort Knox mine was like that, a granite hosted gold (in quartz stringers) IIRC. The author of a book I have on prospecting sold the claim that had the strike for a pittance, The area had produced about 8 million ounces of placer, but no one could noodle out the source, and it was right under many peoples nose in the local granite hillocks. The guy who bought his claim didn’t know any better and cleaved off the covering growth of one after putzing around for a while. I think he made something like a half billion on that hit...
A century ago low grade ore was dumped as unprofitable waste but with modern extraction methods and high prices this “waste” has become a valuable resource.
Yep, everyone likes gold and I think there’s still a lot more to be found.
