SprottAssuming Sprott would have filed if they were acquiring, I think it is safe to say that it's someone else. Maybe one of the firms who are considering financing? Doubt it is an insider as they should have trading restrictions if financing is being contemplated and a term sheet is worked on. This leaves speculators who may also be pumping. I own NKL shares and have stop losses in place in the event we see a large sell off today or later in the week.
