The asteroid set to give Earth a historically close shave this Friday (Feb. 15) may be worth nearly $200 billion, prospective asteroid miners say. What do think makes this space rock so valuable?

Sign and suit me up too, and for Apophis too while we're at it. Based on it's trajectory and so forth, I'd agree that there wouldn't be much more than silicates, maybe a little iron, but it's still worth a shot some time in the future. I wouldn't be surprised if the sun just launches it out to deep space though; our marble is going to change it's course, so we'll just have to see. Perhaps we should try to guide it to orbit Venus for a while? That would keep it nice and warm, probably help with the extraction process.
