DebVan: I believe that an argument of under sampling or rather limited sampling is strengthened rather than diminished by demonstrating that the item in question is actually present in the sampled body. Maybe yes, maybe no. Typically, the lack of any valuable diamonds in a small parcel is the result of undersampling. The presence of a rare diamond in a small sample generally proves to be a fluke, with larger tests. That is, it might take 10,000 carats to produce what a 1,000-carat parcel delivered. There are only probabilities however, not absolutes. I always await Gahcho Kue mini-bulk tests with eager anticipation. I trust you do as well. All diamond mines produce most of their value from a tiny proportion of the total carat count. Regards, WillP

I have always been saying that I think Debeers should have taken much larger samples at GK.Debeers claims they can model with as little as 2000 cts due to the huge data base.While I agree with WillP, that taking larger samples could produce lower grades and values,The risk IMO is worth taking.I think that in production the large 9.9 ct gem will prove to be no fluke.It seems unlikely that Debeers could have got lucky and of the 30+ million tons present put the drill on top of the only large gem in the deposit.1600 ton is such a small fraction to the millions of tons of ore present,that in fact a larger sample may have produced even more bigger gems.This may be the reason Debeers is going to widen the search this winter.Looks like the stock wants to test $5.
