Babymick1 - there are lots of references to John Reed and his and his father's possible knowledge of Waltz's mine floating around on this forum and others. It's too long a story for me to post so if you're interested you'll have to do some digging, but on his supposed last trip to the mine site when he was 12 years old (somewhere in the time frame of 1884) this is the description he gave...
- quote from Thomas Glover's book "Treasure Tales of the Superstitions."
John Reed himself eventually got into contact with the Ely's as well as Bark and Erwin Ruth - and eventually even came out and attempted (maybe) to find the mine site with Clay Worst. Some people claim Reed didn't know anything but was trying to horn in on finding the mine - other suspect he knew more than he was letting on - or even misleading people and used Clay to try to search the mountains so he could go back at a later time on his own and dig out the gold, etc... Nobody really knows.
Anyways - I just thought your picture looked like ore that I would imagine fits the description Reed gave.
