With GRZ trading well under cash in the bank value, this is a "can't lose" trade for any institution with the money to sit it out...

If the stock drops further they just buy more until they eventually control the company and then they can do a deal with anyone to recover the cash and value of the equipment even at a discount.

There isn't one major miner who needs a mill in a hurry who wouldn't jump at the chance to get it at a discount, and get some cash for free thrown in regardless of what happens in Venezuela.
