RE:Helium basesAmerican Helium is pretty much a dead duck in Utah(?) - seriously nothing there, just stay away.
NORTH American Helium is private - out of Calgary is the largest lease holder in Canada and already porcessing helium out of SW Sask - building it's own facility in the area as well.
No investment opportunity - but they have a very good website that shares a lot about helium and the SW Sask area.
