No, i'm not proposing MegaMaid ;)

But, could, if we could find a mechanical or natural means of siphoning materials up a tube... we use these potential resources in space for manned mission resources, or even terraforming? What else could we do with it if it was even possible?

Planetary resources seem to have the primary goal of mining water from asteroids as water is an expensive resource in space. With an ocean or lake ice ball we could then possibly transport it to the moon or mars to extract from. I wonder if oxygen could even be preserved in such an ice ball.

Added bonus we lower a bit of Earths oceans? And in turn creating a shift in our mass and yearly orbit around the sun?
