In case he meant it serious I think Cameron simply has not done his homework right.
Mining on the moon, well maybe that has a very (a VEEEERYYYY) longtime perspective, but catching and/or mining on the occasional asteroid or meteor for several billion dollars per mission is - well, Monty Python would have loved the idea.

The real need is for those basic metals to be used in space for construction of new stations and spacecraft, rather than building them here on Earth.
That water is remass for spacecraft, we don't need it down in the grav well.
The real prize is in the outer solar system; Jupiter has as much methane (a common fuel) as Earth has
mass. Forget pipelines from Canada, we need space tankers from Europa!
