Tim, <<have to be separated and hauled to a dump>> Maybe instead of deadheading the earth moving equipment 2/3 of the removed ore can be returned to the removal site for site restoration? Maybe even power screen at the dig site and then just move the concentrate?

<<consistent assays is because sometimes the pms are in the minus 20 mesh and other times>> I understand that Hewlett has done a good amount of research in that area. His method of fractional milling and assay is some of the result. Too bad IPM wasn't interested, however I understand that IPM now has an assay method that works. It would be nice if at some point a major would become interested enough in the desert dirt potential to apply their laboratory efforts for better understanding.

The issue of PGMs in the desert dirt is still an interesting subject. I agree that area mineralogy doesn't support finding PTMs. I did follow a PGM mining company located near Toronto Canada. Seems that their PGMs came from a meteor impact ages ago where the meteor punched deep into the earth's core releasing large amounts of nickel rich in PGMs. As wild conjecture could meteor impacts in AZ be the source? Wild hypothesis I know, but something produced the PGMs. Something more than chickens or aviation platinum wire spark plugs. <VBG>
