As far as I can tell, all natural gas resources has a percentage of Helium. Since we won't be running out of natural gas anytime soon, we won't be running out of extractable Helium. It just isn't extracted right now because the US is dumping their stockpile. By 2015 this should be done, prices should spike because production was stopped and will take some time to restart, and then it'll go back to "normal".
