Thanks geoprof for some very sound thinking.  You could be right on many of these issues.  I think I echo the thinking of other posters when I say that it is equally feasible for NOT, BMK, SPQ and others to individually prove up enough resource for a mine.  As is the case for all theories and suppositions we'll have to wait it out to see.  I'm also reminded of R.N. commenting on how they are already in negotiations with majors, which tells me that they are perhaps doing more than just kicking the tires and that  knowledge is more forthcoming on their side of the fence than ours.  As much as I would wish any mining in Canada to stay North American owned,  it is equally likely that China, Russia or others could gobble up this area with the kind of resources they have in a blink if they felt it was warranted.  They of course are not fools with their money but they are aggressive and likely to be up to bat sooner than later.  

Again you posed a very sound businesslike approach likely to be taken by a company given your parameters.   We'll see what the parameters actually turn out to be.  Thanks again.
