Buenas, Frank! I'm still around. ;) Preliminary K-91 results had high counts of microdiamonds in the mix, with a couple of nice rocks thrown in, ie, a 1.35mm and a 0.95mm, both clear and colourless
(~ .14ct, .13ct-- see Fe.9/98 NR)
--no comments by the co. on fragmentation, I don't think??
See the K-91 summary results here:
ashton.net.au
-where you'll note the results are reported in <0.5mm & >0.5mm
-however,
when Ashton later gave the boiled down K-91 statistic of an avg of 35.4cpht,
they used the >0.8mm cutoff:
ashton.net.au
--just pointing this out for consideration!
--------
K-14 minibulk results:
ashton.net.au
The results are an encouraging indication that kimberlite K14 contains a population of diamonds of commercial size.
More results from K-14 (remember variances):
ashton.net.au
These results confirm that K14 contains a population of diamonds of commercial size while continuing to show the high degree of variability between samples reported in the November 11th results. This is not considered unusual given the random distribution of diamonds in kimberlites.

Re. pending K-91 ~45tonne mini-bulk showings--
I'm looking for better than 40cpht, but a key issue will be the presence of some good-sized crystals. This is likely, given that we're in the same cluster as K-14. I myself am already predicting a high gem-quality %age, tho confirmation of that must wait for bigger samples. It is not really appropriate to report gem-quality levels at this early stage, but I gotta say it would be nice to learn, even just for ball-park estimates!

Again, remember the size of these anomalies. The tonnages are immense.
