I'm neither in nor out on this pig. I wouldn't touch it with a 10 foot poll. Would take some stellar thing to get me interested in this PIG again. They have a track record for pumping up reserve estimates that don't really exist.
I view Gurupi/JAG as a "low grade" ore play. Forget the drilling results. They are bogus. If the value is cheap enough, and the POG starts heading to the $2K level and higher, then JAG (and the other low grade plays) will do well. SSRI for silver is the same thing. A bunch of schitty, low grade ore.
