Take it to Bedrock
November 2017 by Adam H
Picking the right spot to placer has to do with years of experience, and a little luck. The textbooks can tell you where it should be, but sometimes the rules just don’t seem to apply.
I frequently get asked, "What should I look for when I am out prospecting that will tell me there are good amounts of gold present in the ground?"
...it’s been a little known secret that one man was involved in designing many of the most respected very low frequency (VLF) nugget detectors on the market. Dave Johnson has designed gold-oriented detectors for Tesoro, Whites, Fisher and others for more than 25 years.
In 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.
Looking for nugget laden bedrock in forested mountain regions, you first need to explore the banks of the gold-bearing streams and look for the bedrock that is exposed as this is your starting point.
I could see lots of quartz, both loose on the hillsides and in the numerous small prospect diggings. There was a small gold rush here more than a century ago.
When working fine gold placers with a drywasher, there are some natural variables that can be beneficial as well as others that can be a hindrance to achieving good recovery.
It is the eighth largest brown diamond to be found and certified by park staff.
