I'll offer another option

They did not expect the completion of the BFS to become the ordeal that it did

They thought that the added drilling and slow turnarounds on assays would delay the BFS, having no idea what kind of a clown show was already in store for them

So they opted to shorten the time to BFS by not including additional drilling at that point, with Teck concurrance

Not knowing that it probably would not have made a bit of difference (or maybe it would have) in their getting the report this year
