Regardless of whether they can stockpile or not, the salient point here is that silver in the ground is like money in the bank.
No, BETTER than money in the bank, because money in the bank is gradually and inexorably depreciating in value, while silver in the ground is - and by all indications will continue to be - gradually(?) and inexorably appreciating.
That's why I'm quite willing to be patient and give Alexco all the time it needs to pull the metal out of the ground. As long as the price of silver is going up - or even more or less holding - relative to the dollar's purchasing power it is going to be worth even more tomorrow than it is today.
Silver miners are a very small and increasingly powerful group, not unlike OPEC or the oil companies. Like the oil companies, one can even see the day approaching when they will collectively be in a position to determine how much they want to charge to be willing to part with their increasingly valuable booty.
Think about it: Silver miners own the perfect commodity. If the economy goes DOWN, silver goes up in investment value. If the economy goes UP, industrial demand for silver increases. Silver has a built in hedge that even gold lacks. That's why I believe the gold-silver ratio is likely to continue falling - and the value of silver rising - over the long run, regardless of what the economy does.
