Highbanking for Gold

Pumps can be set up quite a distance away horizontally from the sluice, even hundreds of feet. It will work so long as there is sufficient water at the source where the pump is located. Vertical distance is more of a problem than horizontal distance; 30 to 40 feet is the maximum vertical climb for most pumps.
Ray followed up by detecting the same area and I was happy to see that he did not find any good targets in the same line. So far so good.
We’ve had two trips to the deserts of Nevada and explored mines and mill sites, hiked miles of ravines in California, and swung our detector coils over thousands of square yards of bedrock.
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.
We panned out maybe three gold pans of the material and we were shocked at the gold that was there. This rock appeared to be rich.
It is the eighth largest brown diamond to be found and certified by park staff.
I have been detecting the area on and off since I discovered it. Every time I bought a new detector it was the first place I went to.
These are entry-level machines designed with gold prospecting in mind and with the ability to handle mineralized ground and see nuggets of a grain or so in size, perhaps smaller.
