"...they have in fact hit some near-surface ore?"

That's what I meant because chalcopyrite is the most abundant ore for copper.  And if I interpret older pictures of surface samples correctly, we should also have malachite in the mix, a source of copper carbonate ore.  Hence, the CDR/Scarn link.  

What excites me is this is looking more and more like an analog to the Copper Queen but with a footprint of Bingham Canyon.
