From his early 20s in Africa and later in. Before learning how to identify a raw diamond its important to realize that diamonds are created in relation to specific geologic conditions. Kimberlite ores containing no swelling clay were not prone to weathering under any of the conditions tested.

Kimberlite is ultramafic and has extremely low SiO 2 content 35 wt very high MgO 15 wt extremely low Al 2 O 3 5 wt very low Na 2 O 05 wt and Na 2 OK 2 O. KIM sampling involves taking wide space soil or stream sediment samples separating out the heavy minerals and examining them under a binocular microscope to look for the presence of KIMS. The stilted shrubby tree appears to prefer growing on kimberlite-derived soils which are high in potassium phosphorous and magnesium.

While ground sampling is still necessary airborne geophysical sampling can help to identify prospective targets in an area already identified as a potential host of diamondiferous kimberlites. Given that less than 1 of kimberlites will yield an economically-viable diamond deposit finding a viable diamond mine is a daunting task. Others were found by geophysics which led to the discovery of another group of kimberlite in the State Line district that were found with IMPUT.
