Invasion of the Ore Snatchers

My eggheads are telling me the alien base is causing these quakes! Something about the pillars of the world and strip mining. I only read the first paragraph of that report. It's 300 pages long! There's no time to sit around calculating! We need to find out why they came here!

The aliens roaming the fields seem to be working on something. If you could eliminate the aliens and bring back a Galactic Pouch , we could figure out what they're doing. Actually, bring back 10. The eggheads always want extra samples.

Masteria is in danger. You must help us!

They're after our ore! Those planet-snatching, rock-loving space-jockeys! They didn't even apply for zoning permits! The ore they're taking is super-conductive. They're converting it into a power source!

That explains the earthquake too! It must be their digging machines!

\ Those ore veins are foundation of Masteria! If they dig them all out, Masteria will collapse in on itself like a big souffle! We have to stop them!

We need 10! We need a good sample of the alien Galactic Pouch if we're going to solve this puzzler!
