The conventional wisdom is that asteroids lack the geologic processes
that concentrate ore. I would imagine an ordinary chondrite is fairly
homogenous with various substances distributed evenly throughout.

Bear in mind that nickel-iron meteorites are clear testimony that some
asteroids briefly had active geology -- enough so for the inside to melt
and a core/mantle distinction to get started, with rock in the mantle and
metal in the core -- before they froze and were then broken up.
