Prospecting & Detecting
Detecting Nuggets—Overcoming New Challenges
September 2015 by Steve Herschbach
Depth is not an issue unless the site is thoroughly cleaned of shallow trash, and it is far easier to isolate and remove targets using a small coil in a target rich location.
The Significance of Nuggets in Placers
Chances are better that both types of gold did not come from the same source. Let's look at the probable conditions to cause two types of gold in a placer.
Tips for Detecting Old Hydraulic Pits
There are several counties around Shasta County that offer very good gold detecting. Many of these locations are old hydraulic pits. While detecting these old pits over the years I have come up with some ideas on how to go about hunting them.
Finding Streams of Gold
Without knowing or even thinking about it, I had put together a map that showed me a pattern of the ancient Sacramento River channel. I also had a distinct picture of where the ancient channels of several other creeks and rivers were running.
Nice Specimen Gold Recovered in Northern California
Each specimen is carefully examined to determine if it would be beneficial or not to use an acid treatment to reveal more of the gold.
Proper Assaying of Placer Samples
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.
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.
Heavy Glacial Rocks and Gold in the Midwest
Over the years, I've noticed a pattern in the type of rocks associated with the best gold deposits in Midwestern glacial gravel.
