Price Run Up is Signs of PP ClosingRun up is from the PP being closed. By all accounts it was oversubscribed. Today's volume is from people who couldn't get in on the PP and are now forced to buy in the open market where people are holding onto their shares for higher prices. I suspect It will take a few days for everyone to be notified one way or the other and for the money to arrive in the bank accounts and shares to be deposited.
As for a press release if I was a betting person I would imagine any press release on the PP closure will coincide with OSK's completion of due diligence and an announcement regarding future drilling plans. I bet its another 7 to 10 days.
