Copper has been mined for about 5,000 years so it's exact origin is unknown.
Since copper was a known element at the time that Dimitri Mendeleev first laid out his Periodic Table in 1869, it was included in that first periodic table. Other elements that were unknown at the time, like helium, were not included.
