Bender,
Great point, I am sure companies are thinking about it. However, I am not sure what AB really has? How much Zinc/Copper/Silver? They state that they have all that, but without results or drilling I don't think you can put a value to that.
Notice how they said their NTA has now been lowered from 75cents to 60cents. Again its only on paper, the important piece is cash flow - and that sucks
