I fully understand that is is hard to wrap our heads around a sub $2 stock being worth $20. I get that, but sometimes the market is just plain wrong for a long time.

If the numbers prove out, every miner worth his salt will want a piece of this. Most miners are working on 0-20% margins, not 80%.

To that point, its the responsibilty of every CEO to try and increase shareholder value as much as possible for the owners of the company. While it would be fantastic for company X to pick up zen on the cheap for 5 or 6 dollars, company Y's CEO could also increase his shareholder value dramatically by paying 7 dollars. The whole goal of getting a bidding war setup is to have the larger miners bid up the property until their NPV calculations say to stop.

As a side note, buyouts don't have to be cash deals. It could be a stock offering, a cash offering, or a mixture of cash and stock in the purchasing mining company. Companies that might not have the borrowing capsity or available hard cash to buy up zen could offer a all stock deal in order to be in the bidding process.
