I have heard of the campo bonito mine and buffalo bill Cody , any other mines in this area where exactly has the gold been found ? has anyone already done some research on this ?
Beach High Banker, Sweep Jig, Whippet Dry Washer, Lobo ST, 1/2 width 2 tray Gold Cube, numerous pans, rocker box, and home made fluid bed and stream sluices.
Remember, Google is your friend. Just found these in a couple minutes search and it took me longer to write this reply. Use key words for your future searches such as: near, placer, lode, mine, Oracle, gold etc.
Good luck.
PS it is never recommended to enter old mines for reasons too numerous to list!
