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.
Don’t hunker down and just keep digging in one spot where there is very little or no gold—if you don’t find it, you’ve got to get up and move on!
Lately I’ve been having success utilizing two types of detectors in succession. The first is a pulse induction (PI) detector with a blanket-style antennae, and I follow it up with a very low frequency (VLF) detector.
This time we took the detectors. Roger had worked that spot very well and wanted to see if my new detector would uncover any gold he might have missed.
So why would a modern-day prospector want to learn about a method of mining that was banned by the courts more than a century ago?
The first requirement is permission from a land owner. This can be tricky and it’s always a bit nerve-racking to approach a stranger cold with such a request.
The old report I read indicated all they ever did was dig some trenches and take samples. It sounded to me like a good place to take my metal detector...
If you do the math, it equates to about $1,500 of heavy metal value per three-hour dive. This is good wages, and you are doing a service to the environment by removing this toxic metal.
