I would be very surprised if the rest of the batch had bad grades, it would be very unusual for part of a batch to be chokkas with diamonds and the rest have very few. I think it would be safe to say that they haven't found any further 5ct+ stones though.

It is probably a case of being busy trying to fill the rest of the shortfall and not feeling like the results are newsworthy, requiring the market be updated. We have already determined that BLK6 has good grades, that the rest of the batch contained similar grades would not be a surprise.

I do suspect that once the shortfall is closed we may get an update shortly after.

Having said all that, I do agree that more regular news would be desirable. Three months between results is a long time.
