I think it pays to take 1000 ton samples etc..and drill holes all over, for good form if for nothing else, but anytime you are having a real hard time trying to get handle on a pipe, just send me 100 garnets pheno-xenocrysts of any type from 4 different areas of the pipe, collect about the same number of pyropes if possible, and some 20 lbs of fresh core for other sampling. About 5K in lab costs and an equal consulting fee should settle whether you should spend a lot more money on the pipe. Some stats on whether you saw eclogite, macrocrysts etc. would come in handy too.
If more people had done that in the last ten years, there would have been a lot fewer Tli Kwi Chos and a few more Diaviks.
It all depends on what you are calling chemistry. I would take it that most companies that herald chemistry, not regarding orignal size of pipe, oxidization, erosion etc, do not have a good handle on what good stats really are. So you may be damn well right about that.
But if they did all the work right and I saw the trace and major numbers in p and e probe, oxidation, and microdiamonds, then I would most certainly be tempted to buy stock. It is a lot better shot than Babe Ruth up to bat.
