He's the same clown that got on BNN and said RBY's ounce count would go down substantially because they didn't employ a top cut and the stock would take a huge hit. Not really interested in what he says, since he is clearly guessing and a bad one at that.
I recently heard an interview with him where he made it clear that "Grade is king." He was making the point that ounce count can be very deceiving. He was explaining that many investors only look for the number of ounces touted vis a vi the ore grades.
I think Mr. Cook is a good communicator, and gives investors an honest look at some of the hidden dangers involved in mine investing.
