Ok yeah sure. I have read all that and not from silverdoctors. I mean no ill as I have looked at this for years. It is true, grams per ton is only part of the issue. I wish we could get good data on grams per energy unit. That is the key. It is cost of grams per ton. With more grams per tom the cheaper the cost...yet how much recovery costs in grams per ton, energy per gram return. This is where is gets tricky. @5 silver, not much - copper mines just sell it off the bottom line @10 not so much but still cash for minors @20 -break even for exclusive Silver Miners @ 25+ now mines become profitable and the price stabilizes right? Wrong, demand is growing faster than supply, the ol Feds are out as they have to buy now. Its an industrial metal - my paycheck involves this just not silver...
I don't know if there will really be a lot more available, unless we tap into the core of the planet, since most gold and silver came here with asteroid strikes and will not be renewed at the rate we're using it. It takes a lot more energy lately to get silver and gold out of the ground and we have peaked in regular crude oil production. I expect PM's to keep going up.
