Rough carats/tonneI have done some rough figuring of the carats/tonne for the different pipes reported in the news releases. I modeled each diamond as a sphere with a diameter=sieve size and a diamond density of 3.5 grams/cu.cm.
These assumptions may be way off but they do give a way of rating the relative qualities of the different pipes.

Tuklu-1-3 are very promising, Qavvik 5-6 less so and the rest would probably only be feasible if a processing facility was close by.
