November 2014 by Alex Dolbeare
Science has shown, over the past few centuries, that there is a direct correlation between certain plants and their geophysical surroundings.
Detecting: Getting Away From The Heat And Into The Gold
Within a very few minutes, I had my first nice sounding target. It turned out to be a nice earring-size gold piece that was about a half a gram.
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.
Following Clues to a Hidden Gold Deposit
Many years ago I was in the American Canyon. I remembered a few details about a placer deposit there, so we decided to make a trip down and re-check some of these old workings.
Drywashing in Black Canyon, Arizona
May 2016After the hike and a quick snack break we gathered a few buckets of material to really dial in the drywasher for the most efficient recovery. This involves leveling the unit, setting the riffle box drop angle and regulating the speed in which the material is processed.
Underground in the Original 16-1 Mine
These days they employ the use of metal detectors and carefully scan the shattered rocks, hoping to hear that sound we detectorists love to hear.
Prospecting on the North Yuba
The research I did for “Gold in the Slate Creek Basin” (September 2011 issue) found me chasing a channel out of the LaPorte territory headed towards the old mining town of Brandy City, California.
