If you haven't figured it out by now our AUMN warrant value has plummeted since ECU and AUM amalgamated. It is unfortunate that those in at a higher price per share levels will now be hit with their own margin calls on the AUMN warrants.
My bank / stock trading company is very strict that anything being asked at less than $2.00 per share is called for settlement right away. If you can't come up with the margin call cash, they have the right to sell your shares.
Just thought I would share the bad news. Don't shoot the messenger, please.
