If I understand it they have a dyke/sill/fissure up to fifteen feet wide down dipping 10-15-20 degrees sandwiched between granite. The kimberlite I have seen from snap is a grey fairly hard and consistent rock so I don't think they will run into the ground problems DHK and Diavik had with ground stability.
I agree sampling something like this and extrapolating results is tricky. I view last years mini bulks and this years bigger bulks, not as any sort of difinitive grade calculation but as a method of determining "should we proceed".
In my view the answer to that is a resounding yes. the drilling has shown the dimensions of the dyke and the bulks a grade worth presuing. Some ore bodies you just have to mine to determine the real grade but as they proceed with mining they should through sampling get a handle on grade calculating. It would be akin to taking out a round run a sample and that tells you weither you took out a round of ore or waste.
The clunker here is one or more real large stones can pay for removing and processing alot of waste. If they start mining and find a few truely large stones, then they are away to the races. As we all know some large mines can produce alot and barely break even while some small mines can make alot, if the grade is there.
Time will tell but my quess is they start an open pit and process on site, followed or in conjunction with, a ramp and underground testing.
