Hello DD I am not so sure that the issue is all that new to DB's and therefore probably not new to experienced diamond geologists like CJ et all. I can't recall the name of the pipes, but if you go to DB's site and follow the links to the specifications on their RSA/Namibian pipes, I believe you will find two or three who's grade is not all that exciting but who's values/tonne are, hence those pipes probably have larger stones of higher quality with a relative absence of smaller and larger numbers of stones. Possibly, the diamonds in those pipes tend to be of an eclogitic source rather than peridotitic. Anyway, every Canadian Tom, Dick and Harry with a geology degree has been jumping on the diamond bandwagon since 91 but very few ever took any formal education in diamond geology when they got their goat skins. Much of what's known by the Canadian industry now has come to light over the past decade and real experts are only now becoming more common. For five of those years, most Canadian jr's and their promoters thought all they had to do was look for mag lows with coincident EM highs and drop an NQ drill 20 meters in one direction to find out if they got lucky. Others did the geochemical train sleuthing but still only made small shallow holes in what they found. Only CF et all and later a few key folks at Aber knew that a number of the pipes they were finding were not milkshakes but poorly mixed backfill that required thorough sampling to determine average grade. Hence the resampling of all the Kenady Lake pipes including 5024 and Yamba Lake's Sue, etc. If your bonanza stones are being recovered from alluvial gravels in Brazil which have historically produced exceptional stones of colour and size, I would be cautious about any play claiming to have found the hard rock source. Many wise players have tried and none to my knowledge have succeeded. There are thousands of K & L pipes and hundreds of very unusual brecciated and uplifted peridotitic intrusions down there cut by rivers for eons that could be the low grade sources, and Brazil is not overly friendly to mechanized alluvial operations. That play is truly like looking for a needle in a haystack. Anyway, good luck. Vaughn
