Having the high grades continue seems to me to be the more likely possibility, but we can't discount the possibility that they're two separate zones, with no (or poor grade) minerals between them. Unless and until drilling is done in the in-between region, I prefer to discount the possibility. That way, if they do find high grades in the area between the two zones, I get a pleasant surprise. :)

I'm pretty sure that in-fill drilling in that region is fairly high on the list of things to do.

Honestly, though, I'd like to see the company start making a move towards developing a mine. Drilling costs money; I'd rather have Peak become cashflow positive, and then prove more reserves outside the mining area. That said, management know more about this stuff than I do; I'm willing to trust their judgement.
