LOL There is no potential for PGE's in Nevada, California, etc. etc. etc. etc. Search outside "CONVENTIONAL DEPOSIT MODELS" See below for true answer.

Email From Paul J. Lechler, Chief Chemist/Geochemist ----
"I think that there is potential to find economic PGE deposits in Nevada
and elsewhere. There has actually been little exploration for PGE
mineralization outside of the well known layered mafic intrusions and
large mafic dikes. The high current prices for most of the six PGEs has
accelerated the exploration efforts of many mining companies, even
outside of the conventional deposit models.
