I took a snip from willp and here it is. In order to fulfill SGF's goal of a parcel of diamonds large enough to get a value and grade - they could possibly have to take out as much as 25K tonnes.

"Shore Gold hopes to advance its Star project in a much different way however. Rather than conducting a mammoth drilling program at Star, which might take a several years as it has at No. 141, the company hopes to come up with a large parcel of diamonds to settle the question of grade and value in one fell swoop. To get a sufficiently large parcel, weighing at least a few thousand carats, Shore will have to extract about 25,000 tonnes of kimberlite. Such a large sample might require about 250 reverse circulation drill holes, or about 25 times the number that Kensington and its partners have planned at No. 141 this year. The expense of such an undertaking would be exorbitant, and as a result, an underground sample would seem to be the best way of collecting such a large batch of kimberlite.
Just how much such a program might cost is hard to say. Large, 5,000-tonne underground bulk samples have been collected in the North for roughly $20-million, and the cost in Saskatchewan would logically be much less than that, although ground conditions and the depth of the kimberlite might complicate matters. In any case, a large bulk sample seems certain to cost several millions of dollars, and it seems likely that Shore will have to come up with more cash in the coming months. Nevertheless, the company seems off to a good start. "
