Gold in the San Francisco District Oatman, Mohave County, Arizona
December 2013 by W. Dan HauselI suspect detailed geological mapping and prospecting would lead to discovery of one or more overlooked gold deposits in the district even though it has been heavily prospected in the past.
...more folks rolled in on Saturday morning and many were eager to venture out onto the Sleepy Bear property—all 415 acres—and try their luck at finding some gold.
The 2011 gold season had finally got underway on the Middle Fork of the Feather River near Quincy, California. Cold weather and high water had pushed gold mining into mid-summer, but things were looking up.
If the material drops down out of the hopper too fast, it can overwhelm the riffles and you can blow the gold right out. If it runs too slowly, the riffles can clog up and the process is too slow.
I like to think in terms of “conductive mass” because it is a combination of both the conductivity of the metal and the size of the target that determine how a detector sees conductivity.
I love it when I am in the middle of a high trash area and all the ferrous bars go away, the screen number goes to a three or an eight, and the meter is forty to a hundred. I don’t know for sure that I have found gold, but it narrows the odds down.
My third sample location proved to be my last and most interesting. I needed to look no further.
It is the eighth largest brown diamond to be found and certified by park staff.
