Prospecting & Detecting
Keep Watch for The Unexpected
May 2019 by Michael Greyshock
As I have always done, I stashed those heavy black rocks in my pack and put them in the garden at home. They never were given a second thought until a half decade later…
The Half-Mile Claim
We dug and extracted for two more hours. This time, as I dumped the concentrates, I saw a piece of gold three-fourths of an inch long and as big around as a pencil.
A Successful Trip Through Gold Basin
This time we took the detectors. Roger had worked that spot very well and wanted to see if my new detector would uncover any gold he might have missed.
Recovering Fine Gold with Oleophilic Adhesion
Oleophilic means "affinity to or attracted to oils," and this includes gold an diamonds.
Old Mine Sites and New Technology
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.
How to Find Prospects That Others Missed
Every year I go through this and every year it becomes more difficult to find new territory that is available for us to prospect. Is there anywhere that hasn’t been worked?
Prospecting for Diamonds
Let’s take a look at diamonds and diamond mining and see how they form, how they are used beyond just jewelry, and what leads geologists to find diamond deposits.
Sniping for Drought Gold
There are not a lot of tools needed to get out and take advantage of the situation. Other than my wetsuit, I typically travel light with a gold pan, maybe a pry bar and a few crevice cleaning tools.
