First time I've heard of Michigan copper in the old world, looks like an interesting rabbit hole to explore. Transatlantic trade secrets being lost in the bronze age collapse is definitely very possible.
It is a really interesting rabbit hole - i first came across it in, iirc, Hancock’s Fingerprints of the Gods and it helped tie together a few things that seemed anomalous but disconnected, like the level of sophistication seen in prehistoric America (the Mound Builders, South American pyramids with surrounding populations plausibly in the millions despite having all but vanished into barbaric cannibalistic remnants by the time Europeans show up), the common building patterns (e.g. megaliths, PSM, and pyramids) showing up around the globe, and so on. Hell, it even ties together with the Book of Mormon of all things lol!
