Well, we haven't actually gone out there and assayed any asteroids,
of course, but the nickel-iron meteorites found on Earth have all
contained a significant percentage of Pt-group.  The Sudbury deposit
in Canada is the remains of an ancient asteroid strike, and it supplies
Pt/Pd/Ir and such as a byproduct.  And the iridium in the K-T boundary
layer is considered pretty convincing evidence for the Alvarez 
theory that a major asteriod strike is responsible for the massive
wave of extinctions at the end of the Cretaceous.

So platinum group metals being available from asteroids seems a pretty
good bet.  If we can get out there.  And especially, if we can find any
that don't have Soviet claims already staked, which may be a considerable
problem by the time Our Congress finally gets off their backsides.
