Roger,
I just can't figure out why you are basing this whole thing on Capt Pauline Weaver. Yes he was a part of the group that developed the La Paz Placers, but it honestly didn't last that long and he moved on to Rich Hill and then down around Prescott and to other parts of AZ. He died a camp Verde, AZ in 1867 apparently dead broke. I will agree that this man was a noted frontiersman and prospector and apparently had a pretty exciting life. But nowhere and I mean nowhere is there any evidence that he located the richest mine in the world. Most of those very early prospectors in AZ were looking for the easy surface placers and when thy were exhausted, thy moved on, an this was the story of Pauline Weaver. He certainly was an active prospector but their is zero evidence or reference of any sort that he found the really, really big one. He was involved in the early workings of Rich Hill and that was a big one, but he even moved on from that once the easy surface gold was gone
