In any event, that fact that there is a major difference of distance between an asteroid's surface and its core, and Terra's surface and its core, is not an indicator that former planetary core fragments will be filled with mountains of valuable metals that will be easily exploited.
The pressures at the Earth's core probably cause everything to exist in a heterogenous state. Mass seas of nickel/iron mixed up with vastly smaller concentrations of the other metals dispersed among the larger mass.

Also, planets are extremely unlikely to form around the types of stars that will go supernova. The lifespans of such stars are too short for the planetary formation process to complete.
This means that when a star goes supernova, there won't be any planets there for it to burn to a cinder (or blow apart).
