Hmm, interesting. I was thinking that we could mine fresh debris from the asteroids themselves, in concentrated form. Plus saving the earth, of course.

GP's point is that plenty of asteroids have crashed into the moon in a recent enough time frame that the debris is still "fresh". After all, there's not much erosion on the moon.

Yes but not all in the same place, so the ore would presumably be less concentrated?
