Well, I think it's safe to say that after next week, or even the week after (I would allow for that scenario) it would be a bit unusual for results to take that long.
If the drilling had stopped, and the assay's were sent in regularly along the way, then 2-3 weeks after drilling stops should be plenty of time to get assays back and analyze results and write a PR. Any longer and it's either for a reason (good or bad, who knows) or the company is just slow. And I think that then, a certain poster would be dangerously close to being right about something and I don't think many here would like to see that!
