Hi Bob: I wouldnt read much into the word "mixed". There is a definite relationship of G-9., and G-10s to probable diamond emplacement in primarily perioditc orgins. There have as well been sources which have abounded in G-10 garnets and yet were diamond barren. So a lot of things have to happen besides mineral picking and probing. When Gurney used the ca G-10 plots., he predicted with some certainty the eventual grade of the Jwaening mine., his work probably has been the benchmark for classical kimberlite exploration programs. By classic., I am referring to primarily kimberlitic emplacements of perioditc orgins. It worked very well in Botswana. It remains to be seen if it will work in Maritunia. The garnets mentioned implies in a likelyhood the proper pressure was present to form diamonds. Many times diamonds are found with perioditic garnets included within the stones. So you know the garnets sampled the diamond stability field. Lots of things have to be right for diamond preservation and grade. I would consider this a nice beginning and will see what developes as the program proceeds. I dont know of a direct relationship between G-9 and G-10. to each other., but as in the case of the Jwaening they plotted very high in relationship to the other garnets present. I guess Maritania sources may fall into conventional classic despcriptions., but it is too early to tell from the data presented. It does point to a classic kimberlite system though. Hope this helps George J.
