OPM - I have no expertise or particular knowledge regarding your claim about the amount of silver left behind when mining copper, gold etc but am prepared to take it at face value. You say the cost of retrieving this silver wouldn't be high. However in the short to medium term (while silver trades form $20-$40 and potentially higher)this will still take time and therefore there will be an opportunity for companies that control these sites to make mmoney. Do you have any thoughts on which companies might be well placeed to exploit this opportunity?
