Copper would have been especially useful to ancient humans as it was much stronger than gold, hard enough to be made into useful items such as fishhooks and woodworking tools, but still soft enough to be easily shaped, unlike meteoric iron. The same deposits of native copper on the Keweenaw Peninsula and Isle Royale were later mined commercially.
The Old Copper Complex of the Western Great Lakes is the best known, and can be dated as far back as 9,500 years ago. [4] [1] Great Lakes natives of the Archaic period located 99% pure copper near Lake Superior, in veins touching the surface and in nuggets from gravel beds.

Native copper is an uncombined form of copper that occurs as a natural mineral. Copper is one of the few metallic elements to occur in native form, although it most commonly occurs in oxidized states and mixed with other elements. Native copper was an important ore of copper in historic times and was used by pre-historic peoples.
Natural bronze, a type of copper made from ores rich in silicon, arsenic, and (rarely) tin, came into general use in the Balkans around 5500 BC. [104] Alloying copper with tin to make bronze was first practiced about 4000 years after the discovery of copper smelting, and about 2000 years after "natural bronze" had come into general use. [105]
