Another Prospecting Adventure: Coulterville
November 2021 by Dan Stanton
What also helped keep Coulterville alive was the fact that the town itself happened to be sitting on top of one of the richest veins in the Mother Lode. The ledge itself was three hundred feet wide.
We just completed a trip to another river, and yes, there was definite movement and redistribution of gravels, and other prospectors have seen this as well.
I am learning more about gold deposition in this area than I knew previously. I am passing this information on with the hope that many of you will be able to locate patches and lines a little easier in the future because of this article.
The problems of the submersible dredge tube are addressed by the subsurface dredge, where the enclosed sluice recovery tube is suspended from a flotation assembly...
After he excavates the ore down to bedrock, he goes over the bedrock with a metal detector to ensure he didn't leave any gold behind before he backfills the area.
Even with my favorite top-of-the-line gold detector there were several false digs. Many of the hot rocks gave a solid signal that was too much like a nugget to ignore. After trying several tests I just dug everything because it is better to be safe than leave a big, deep nugget for a more diligent gold hunter.
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.
