"I wouldn't think that there would be any tax implications, mergers  generally are structured so as to avoid adverse effects and I'm  confident this one will be, too."
I would agree.  But I'm wondering about page 6 of the presentation, where it says:
 - 0.0500 Golden Minerals shares plus C$0.000394 for each ECU share
 - To be implemented via a plan of arrangement
 - Taxable transaction
Not sure what they mean by "taxable transaction"...  Hopefully only the cash portion would trigger a tax event.
