Here's a little item I found on another forum.

Astrobleme,
One of my young guys stumbled across this a few days ago... tested it. Diamondiferous Kimberlite exposed right on top of the ground. Of course it is now claimed done and dusted. Onward's and upwards! Cannot wait to get my teeth stuck into this bit! DD Pic 1 Overview of the area Pic 2 A few indicators. Have fun out there! |
