Prospecting & Detecting
The PIGMI—a DIY Crevice Tool
April 2017 by Tom Leftwich
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.
I Finally Made It to Northern Nevada
After a while I got a very nice signal and out came a sweet kidney-shaped bit of gold weighing about three grams.

Palladium may well be an underexplored element and therefore an opportunity for prospectors and geologists. This is because they are often less than obvious and other than the native metals, a chemical analysis of samples is required to identify PGM-enriched rocks.

George was considering filling his dredge floats with closed-cell foam, ensuring that there would be no area available within each float for flooding.
Downieville: Another Gold Rush Favorite
I didn’t know what to expect because the area we were working was not close to the water, but we were pleasantly surprised when we began to pan out some nice flakes and a few pickers.
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.
The Perfect Summer
Within the first 3 hours he and I had found pocket after pocket of gold and couldn't wait to tell Levi of our treasure.
