Greetings,
A bit late getting to this, but we will see if it goes.
The famous lost Breyfogle gold mine is one of those close to my own heart, and I have to admit having spent some time looking for it. What a bonanza, with ore so rich it assayed something like $13,000 per ton with gold prices at $20.67 per ounce!
The area is spectacular for natural splendor, covering a rather vast area stretching from S. California into Death Valley and even Nevada. The ore is real, the region is HIGHLY mineralized so there is good reason to suspect the ledge is genuine, and sad to have to say this and be the "wet blanket" but unfortunately for us treasure hunters, is all too found.
I would not believe that the mine had been found, as I have run across a great many extraordinary claims of folks who say they found this lost mine or that lost treasure only to discover they indeed had found some lost mine, but only a known and abandoned one, or the treasure was really an old trunk with rotted old clothes in it. So until I actually saw with my own eyes the ore of the "found" Breyfogle, which is known today as the Amargosa mine in California, I did not believe the reports. Again, sad to say but the ore from that mine is identical to the few ore samples that Breyfogle left with various friends in Nevada. As any geologist can tell you, no two gold ores are identical, and an expert geologist who did examine the two ores (Breyfogle and Amargosa) pronounced them to be identical. I later learned that even Breyfogle himself knew this; for he was once spotted wandering about close to the mine and went over to look at it - then left and NEVER went looking for his lost mine again. That alone is a strong indicator that Breyfogle knew his mine had been found and was being mined.
Anyway sorry to be the bearer of bad news for treasure hunters, I generally wish to encourage fellow THers but in this case it would be a very real waste of your time. That being said, there remains a very rich placer associated with the Breyfogle mine, which was found by men searching for Breyfogle's mine in a canyon that eventually connects to the Colorado river. If I knew more details as to the location, I would sure be there but I don't know any more than this. So the location cannot be TOO far from the Colorado river, but how far it is anyone's guess - and it would be in California.
