Short covering?  That would be my guess, there are 177 odd million shares outstanding.....whether they're bought on the TSX or OTCBB it doesn't matter, the number doesn't change.  Shares bought on the OTC can cover shares shorted on the TSX or vice versa I am sure.  

I'm also thinking we'll see the OTC price drop back to in and around where it was on Friday by the close...in the $1.30 to $1.35 area.
