History of Copper | When Was Copper Discovered?
In North America, extraction of copper started with marginal working by Native Americans. Native copper is said to have been extracted from mines on Isle Royal using stone tool around 800 – 1600 BC. Around 1000 AD, copper metallurgy was fast flourishing in South America especially Peru; it spread at a much lower rate across other continents.
