As far as I recall, there is no mention, in the recent update, of continued work on the concentrate and reject material.
At this time, I suspect that the cash position of the company may be dictating where money should be spent. If this is the case, perhaps Snowfield has opted to leave the bulk sample material for later and concentrate on getting the new cores processed, while continuing the exploration drilling for further kimberlites.
I do not know for sure what the short term strategy is, but perhaps someone else has had a chance to talk with the company.
