$2 Trillion in metals? Seems a stretch...right now the total metal value of the Pebble deposit might be around $500 billion (keep in mind the current mine plan is to "only" mine about 12% of it.
Still, to get to $2 trillion would require that metal prices move up about 3 fold (not at all implausible to consider $5400 an ounce gold within the next 30 years) or...that other Pebble sized deposits are confirmed (eventually) over the next 30 years or so. A partial combination of both could in time lead to a metals in the ground valuation of $2 trillion...though it might take 100 years or longer to get them out! The most valuable company on Earth today is Apple with a market cap of around $1.5 billion. My guess is in a hundred years people will still need copper and gold will certainly continue to be highly valued.
My opinion is that NAK will be trading over $2.00 over the next 6 months. Regardless of who wins the election the gold will ultimately be extracted as all great buried treasures eventually are dug up. Any mining company would be foolish not to buy NAK, even if the they have to wait longer for its eventual full development. The prize is worth it!
