Iron outside = Iron inside

Thank you Andy.

There are many interesting asteroids.

The bulk of them, however, are simply stoney. Only about 4% of NEA's
are the Iron-Nickel type. But that's still a hell of a lot of
Platinum.

What's exciting is the Iron is pure. It's not like the Iron on
earth, mixed with lighter elements and, because of this plus earth's
gravity, comparatively difficult to process.
