RE: Sprott is buying constantlymargin calls take days or even weeks to play out. I had many,the bank will usally send you a letter after a few days and give you a week to bring in more cash,more marginable securities,or sell something,if you do not comply,after a while they will sell something to bring your account current.I think anybody holding ARU on margin(marginis only 25%) will just hope the price goes back up and they would have to do anything.
