They can be like the Iron Range of Minnesota was for the Detroit car industry a key resource located near where it was needed.
What a preposterous sentence. The Mn Iron Range is still there, it's still 1000X closer than an asteroid, and there is still enough iron there to supply Detroit and the reset of the country for a thousand years.

Just attach a guidance system onto each asteroid that guides descent to the desired location, say, the Mesabi Iron range area. May be a bit of cleanup after impact, but much cheaper.
