Prospecting Underground: Use Caution
April 2011 by Don RobinsonIn underground placer work, the contact point of the bedrock tunnel and the gravel is a very weak point and always has to be timbered. The bedrock here is thin, fractured, and the gravels loose from many years of oxidizing.
...it's very refreshing to hear that some of our youth will learn of the value of mining without all the environmental spin.
At first, I tried to shift things around, but then a hand with a rock would appear, so I would stop trying to adjust my gear and grab the rock to keep things moving.
We decided to check some spots that were pretty good to us on previous trips. The detector was deceptively simple with few buttons and auto-ground balance.
We spent the morning in a meeting with one of the higher-ups at the US Forest Service. I presented him with 412 complaints received from our readers, along with a summary of the complaints to make his job easier.
Mike and I each selected a side of the creek and started to work our way upstream. We both worked the water and sides of the creek, and better than half the gold found in this area is in the water.
There is a surprising amount of detectable gold under the water’s surface. The right tools make it much easier to find, and with a little patience and practice you can take advantage of this underappreciated bonanza.
