My only thought on Northern Dynasty would be that the grade is pretty low. In these days of low gold prices grade counts for a lot. Also they have permitting problems. Not one I’m wild about. JMO
I remember when I owned it years ago, John Embry was doing an interview and in it he termed their ore “dirt.” An exaggeration for sure but what is, is. It pissed me off at the time.
