--thanks--having been a hardrock miner most of my life, I'm more interested in what are the ultimate sources of geologic wonders such as the porphyry copper deposits, the Homestake orebody, etc.,--

I’ve had an idea that many concentrated surface ore bodies came from the cores of crashed asteriods. May be totally off-whack here though.
