RE: Technically and fundamentally sound I don't think Corvus is a pump and dump at all.
But the Cardero Group have been associated with a lot of pumping and dumping in their lives. Management has been seen giving themselves loads of free shares, paying for a pump, and then dumping their shares into the spike.

I'm saying if you're going to buy KOR make sure your eyes are open, not closed. Don't spit in my face just for wanting to give you a heads-up on who you're dealing with.
BTW, Quentin Mai is nothing but an IR guy for Cardero. Him buying shares is less significant than were a geologist to buy shares. Then again, he's done IR for Cardero so long, he must have a good bank account by now....
