Each Class A asteroid contains just one ore core. To get it, you have to keep drilling until all the outer layers are gone and only the center circle with the core symbol is left. Keep the drill within this circle for a few seconds longer and the asteroid will break up and release it's core. If you abort or fail the drilling process, you won't get the core.
