			Hi Jeff,
 Welcome to the forum.
 True, mining in the Mojave Desert has been going on for more than a thousand years, if one can trust the written word. Mining gems and a lot of other things.
 
 Could your mill balls go for Indian wootz ingots, or should I ask, how much expert do you have to be, to see that they are not Indian ingots, remembering that most of us have only seen ingots on pictures?
