Prospecting & Detecting
Old Mine Sites and New Technology
September 2018 by Jack Geck
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.
Summertime Gold Panning
I have smaller pans for cleaning black sand concentrates, big pans for taking large samples, pans with corners for pouring out materials, and pans with lots of special riffles. This variation is why I have so many pans—they each have their specialty.
The Essentials of Dry Washing
Most dry washers have a feed rate adjustment. It needs to be set so that the material flows evenly over the riffles and does not bury them.
Green Valley Reconnaissance
During this trip we found enough gold to make us want to come back, even with the punishment of a very long, tough hike.

Prospecting for Gold at Green Valley
In October, five of us decided to take an exploration trip into an area called Green Valley. This was perhaps ten miles upstream from where we had gone in September and the difficulty was access. One would think that based on the name it was an easily accessible area not far from a nearby town. This couldn’t be more wrong.
Nome Offshore Dredging Creates Challenges
The Alaska state government has been trying to keep up with and maybe even stay on top of the situation by studying the problems associated with rapid growth and how to solve them.
Sierra County Gold—Part I
...this county contained some of the richest placer ground found in all of California and still produces some pretty impressive finds to this day.
