Palladium Minerals - There are very few APEX eligible Palladium minerals.  

Cabriite (Pd2SnCu) with 54% Palladium is the best choice for APEX Mineral.   It is only found as small inclusions on other minerals and is extremely rare. The Cabriite inclusion above is the dull gray little ball.

Palladium ore deposits are rare.

Palladium is one of the six Platinum Group Metals.  These are precious metals which have similar physical and chemical properties, and tend to occur together in the same mineral deposits.
