I don't think you'll see a counter-offer from Barrick. Barrick is known as being risk averse and specializes in low-cost mines. I don't know enough about the others to comment.
Schmuckie.....You obviously don't know much about the FDN deposit as it is a very high grade mine to be and will be a VERY LOW COST MINE...
You also better go look at what Barrick has to spend on one of its' low cost mines.....billions !!
