Yes, the rotary core is brought in once the core-auger samples have been analyzed and from them it's decided that further drilling is merited. The auger serves as a very cost-effective means of retrieving core samples, checking OB depths, etc. I am assuming the new core drill is a diamond core-driller. Anyway, due to the bringing in of a more rugged rotary-core drill, it seems to me that it can almost safely be deduced that internally, the pulled material was ascertained to be kimberlite. Externally, a lab workup must be there to verify before any such announcement. Also bear in mind Doug's comment re. the further flying in the area looking for similar magnetic signatures. Doug, you make a valid conclusion re. the rushed further, tightly spaced flying of proximal lands (the MMU, MMU/CG, and MMU/MIX properties in the Chinchaga region). This should be a happy crew! Violetta, I don't think we'll see any greater delay than the 3-6wk projection in the NR. Again, I'm hoping for earlier pre-cursor sample results! But, yes, I remember the olivine delay for ACA v.well; that's where I learned about it (as I bet you already guessed!). *Bear in mind that the olivine reference here is mine, not the company's. And in terms of the extra-hard unit that was twice encountered on target 7 (2 separate holes at similar depths), ..., hmmmm. It seems too shallow for the igneous diatreme which would match such a description. For if the kimberlites have had little or no erosion, the upper 2-300m would be crater facies. If it is diatreme kimberlite, that would be quite spectacular, for therein can lie the richer deposits of diamonds, acc'dg to what I've read (if K is diamondiferous). I guess any kimberlite could be pretty hard, depending! -- It's way too early to make any type of valid conclusion of course. And please remember, I am no authority, only a learning investor!
