In regards to homogeneity. We have no way of knowing that the results won't be homogeneous once mining starts. It could be that the grades are homogeneous at given distances from the source and that the grade of the very distant portions is somewhat poor. This has been hinted at from some of the CF results and WSP staff.
At what sample size do you expect homogeneity? If we were to take samples shovel full by shovel full I am sure that no one would expect consistency. Perhaps 3000 tonnes is no way to ensure consistency because of the presence of large stone which skew the value. If there were many small stones of equal value the results would be more predictable but even at the 3000 tonne level if a 30 carat stone pops up it might skew the results by $40 to $50 dollars per tonne.

"Dikes are rarely homogenous, but layering or banding can be relatively consistent over large distances. Kimberlites often display sorting or winnowing characteristics depending on the proximity to source feeders and various other effects during fluid emplacement."

The same thought as one i heard this morning, in almost identical words.
Made me think of your post ... there is imho a good chance that this 3000t will come in considerably higher than the previous. It would be asking a lot to expect value per tonne like that of the rich pit last year, but it is not imho out of the question either. I say +$230US/t if there's a guessing game on ... it's very freeing, a halt - you can say hypey things without being accused of trying to manipulate the stock price -g-
