You could mine it from asteroids, which have plenty of base metals. There's already a speculative market for investors wishing to mine them. The only thing is; the technology for transporting it around doesn't exist yet. (We can land probes on them however for recon, but that's about it so far!).

You might be overestimating the mass of asteroids. The total mass of asteroids in the asteroid belt is 3% of the mass of the moon. Kuiper belt is 2% of the earth’s mass.
