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.

A New Prospecting Spot
Once indicators start showing up along or below a contact I start to get excited. When I have shale, and outcroppings of diorite with iron-red, gritty soil and some clay thrown in, I really get lightheaded. I may be a mile away from the nearest diggings but that’s okay. I just found a spot that could provide some nice nugget hunting.

Fountain of Youth Gold
Across and downstream of our operation was a large pile of huge boulders. It was logical to think that water forces may have deposited gold in and around these boulders. We moved our dredge over and started pulling the rock pile apart.
