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...
The PIGMI—a DIY Crevice Tool
I’ve had great success using it to gather gold from crevices. I’d like to share the design with all of you gold miners reading this article and hope that you get as much satisfaction building and using it as I did.

The whole purpose of sampling mineralized ground is to measure the values in a small volume of material that would be representative of a much larger volume of similar material. The key word is representative. Chemical and fire assaying will not accurately represent placer deposits by themselves.
Gold in Unlikely Places
Detectors have been around for decades now. And with thousands of them swinging, many of the best or at least most likely nugget places have seen a swinging coil. The part that amazes me is that so many nuggets still get pulled out of these seemingly pounded places.

It's Not Always El Dorado
This was “pocket” country. All around were “pockets” that had been hand dug by old and new miners.
