An asset is only worth what someone will pay for it.  Be it a car, house whatever, an owner has emotional attachment to it and always wants more than the asset is worth.  If a bonafide offer came say at $5US and Zen management negotiates the price up several dollars and then no other offers come in, that is what the company is worth at that time.  They would not go through the pain and agony of trying to develope the mine themselves.  I believe AE and crew would take the money and run off to their next adventure.  And so would you and I. 

ZEN management are not miners as we all know.  They are explorers. Go ZEN!
