It sounds as if the indigenous Norte Americanos had a somewhat earlier bronze age than Africa, Europe of India. Hmmmm.

250,000,000 worth of near pure copper ore. Where did it go? The finding only shows when some mining took place but tells nothing more. Was it all taken then or was the vast bulk taken far earlier by another means?
That amount in that purity would have supplied all of the Copper and Bronze Ages world wide.
Oddly enough, they didn't. They made use of copper though. By 1492, there was no bronzemaking in the Americas. The Spanish looked for and found tin, and started making bronze cannon. Precolumbian mining of copper though really took off in what is now Michigan, which may be why Central American cultures that made body armor (of a sort) out of cotton never needed to figure out bronze.
