Prospecting for Diamonds
January 2013 by Chris Ralph
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.A Model Mining Operation
After he excavates the ore down to bedrock, he goes over the bedrock with a metal detector to ensure he didn't leave any gold behind before he backfills the area.
The Importance of Prepping you Gold Detecting Spots
If you want to get better gold you will need to put your detector down for a while .
Do Gold Nuggets Come Out At Night?
There were many small gold placers found and worked in the deserts in the old days, which had then been pretty much forgotten about. We all tried to be the first to re-discover these spots.
Panning on North Fork American Yields Good Gold
This second trip down was a challenge. It started in Colfax on the Stevens Trail, where the distance to the river is four miles with an elevation drop of about 1,000 feet.
Cherry-Picking for Gold Nuggets
We have a location where nuggets over an ounce have been detected over the past twenty years. This location is a small hilltop on which an ancient river channel once flowed.
Indicators and Hillsides
The placer gold shows up in ground sluice areas, hydraulic pits, secondary channels and hillside diggings. It is coming down the hillsides from an ancient channel left high and dry millions of years ago.
It's Not Always El Dorado
This was “pocket” country. All around were “pockets” that had been hand dug by old and new miners.
