Unfortunately, they are not labeled by location.  This makes it a little
difficult to use them for planning a mining expedition, although they
do give us a reasonable idea of what's out there (somewhere).

No, but it makes six locations (actually a few more if you count results
from some of the unmanned probes as supporting evidence) known quantities,
and it gives us some notion of average properties.
