Prospecting & Detecting
Prospecting for Diamonds in Kimberlite
January 2014 by W. Dan Hausel
Kimberlite 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.
VLF Detector Operating Modes
It is important to note that discrimination is a type of electronic filtering. The signal is analyzed, and depending on the discrimination setting, identified as either a target to be dug or a target to be ignored.
Why So Much Gold in Nevada?
Nevada produces about 75% of all the gold mined in the US. This means that all the other 49 states combined only produce 25%, and this includes California, Alaska and Arizona.
Green Valley Reconnaissance
During this trip we found enough gold to make us want to come back, even with the punishment of a very long, tough hike.
Detecting For Gold—Are You Up For It?
Over the years that I have been detecting for gold I have had many of the same questions come up. I decided to write this article to hopefully answer some questions that a person wishing to detect for gold may have.
Gold in The Midwest--Part I
Gold can potentially be found in all the glaciated areas of the Midwest, but to find it in any appreciable amount one needs to look to areas where the gold gets concentrated by more recent water flows.
Pinpointing for Gold
This rock had been with a family for many years and they were cleaning up an old workshop that had lots of minerals and miscellaneous “ore” samples.
Metal Detector Testing Methods
It will not be any easier than on your table at home, and so testing a very small test target like the ballpoint pen can tell you immediately if a detector is suitable for looking for tiny gold nuggets.
