Prospecting for Diamonds in Kimberlite
January 2014 by W. Dan HauselKimberlite is very difficult for geologists to find, let alone prospectors and rock hounds. This is because kimberlite is rarely exposed on the surface and few people know how to identify the rock.
This is just the type of specimen that could have been easily ignored by the old-time miners. It felt a little heavier in my hand than a chunk of quartz of that size ought to have been.
Right away I got a target, and it ended up being gold from a nice little bench. With only an hour left of daylight, I continued heading upstream and found five more tiny pieces of gold with my VLF…
Watching for these areas is one of my primary targets during the winter. It doesn’t take but a few inches of the surface moving away to give a fantastic target response that you didn’t hear prior to the washing of the surface.
The first thing I realized was this was not a toy—this thing had power and I needed to really pay attention. I got into position, took a deep breath, and pushed that monster into the hard pack.
Sampling other people's stockpiles or dumps has some inherent risks that sampling undisturbed ground does not have.
Some experienced panners with the vigor and longevity to spend a full day panning in the small creeks and ravines can possibly find as much as a gram or more on a good day.
It’s worthwhile for the prospector using a metal detector to know a little bit more about the association of iron and gold as well as how iron minerals affect your metal detector.
