GRAM are being opportunistic to the extreme..
In Sept 2009 GRAM thought PNA was a good buy at $2.53 /Share, when they bought 20% of the company. They took advantage of a low copper price then as well because the Price of Copper in Sept 2009 had dropped to about the same as it is now in US $$s
Also there was no Takeover premium attached at this price.
Why would they expect to get it for less?
