I normally wouldn't be to worried, as I've seen stocks many times sold down at the end of the quarter only to rally out of the decline just as fast at the start of the next quarter. The PFS and the timing of it's release you would have thought would have made this stock immune from any sell down.
If the PFS is anything less than brilliant I'd expect the share price to go lower. I've been in a number of miners or explorers resently that have come out with reasonable announcements and the stock has been slaughtered.
If I take a lose on this one think I'll sit on the side line for a while and wait for the market sentiment to change on explorers and miners. It must do eventually.
