What I've seen since I started looking into this is a report of a purported
ceramic mold fragment discovered in Ohio. However, there is considerable
disagreement as to whether that actually is a mold fragment or not. It is
also far from the native copper sites being discussed, and hasn't been
dated to the time frame under discussion. So it sheds very little light on
the subject of pure copper casting.
