I know this is a loaded question , but realistically where does most of the Platinum come from in the USA , and no smart answers like in the ground . LOL
I have found some at Horseshoe bend, Green River, Utah. actually found more platinum one day than gold, but only once I have found it.
Ez to find in Trinity/Shasta counties. My biggest shiny pt nugget is 2.5 dwt(Trinity county) with many smaller less attractive nuggets from all over the state. Merced rocks with ugly nasty rhodium also with all the pt family of minerals. State bulletin has complete story on calif pt group metals of same title-John
When gold hit $2k a oz rhodium hit in the $5500 range and sold every grain I ever found, traded or bought....love them highs as sold my nasty tiny micron gold also. Keep them nuggets though as $2k+ will rise again as this new bubble is already busting at the seams yet again due to insane monetary policies-John
