I can only conclude that when Sprott reps quote numbers, they are not likely to do so lightly. Consequently, their math is based on a few details that may have eluded our hub estimators or have been left out of the mix. They have one advantage we do not. They can afford to transport their reps anywhere to talk to anyone thay want (kick the tires) likely most any time. Owing to their high stature, R.N. likely makes them comfortable in doing so.
