America’s Forgotten Copper Reserve: The Upper Peninsula’s Ancient Treasure
For more than 6,000 years, the shores of Michigan’s Upper Peninsula have produced one of civilization’s most valuable resources. Long before Rome, before the Bronze Age reached its peak, and long before Europeans set foot in North America, Indigenous miners were extracting native copper from the Keweenaw Peninsula and Isle Royale. That same metal helped electrify America during the Industrial Revolution and today powers everything from smartphones and AI data centers to electric vehicles and military technology. The richest deposits may be gone, but the story isn’t over—Michigan’s remaining copper could prove to be one of America’s most important strategic resources for the next century.
