what happened to my two posts, one discretely insulting my buddy DOC??
Pegger, on the legal aspects I am not your man sorry, but there are many here that are..
As for recovering your Pt from the Cu, hmm, it is far far more complicated than you apparently imagine.
In regards to assaying it, there are probably only handful of assayers competent to correctly do this in the US. A friend of mine lost his shirt this way. He relied upon two assayers for the Pt content of a dump that he bought for it's pt content.
The first practical vessel made out of Platinum was done by mechanically joining the pieces of placer Pt together by hammering them. - cold fusion process? ehhe.
The iron canon with Pt were made from iron ore in the new world, this is why they have the high pt content which incidentally actually weakend them.
I have Pt in the TAYOPA ores, in fact there was a minor rush in the old days at near by San Luis Barbarocos.
