This is an excellent report. It was clear that Poverty Point was the natural nexus for manufacturing export copper. after metal and ores were brought down the Mississippi. Likely charcoal came as well to facilitate smelting.
I have written and posted on this for a decade and what this does is fill in the massive archeology that needed to exist here in particular. It matches anything elsewhere in terms of scale. Bimini is also mentioned as it is the natural safe port to go to in preparation for the Atlantic crossing by way of the Gulf Stream to Ireland and the Irish Sea before sailing south to reach Gibraltar.
It is also possible that copper out of the Rio Grande made its way to this facility as well for blending with the better metal ores.
Were Prehistoric Copper Oxhide Ingots manufactured on the Mississippi coast near the mouth of the Mississippi River?
