Recently, scientists from West Germany found an old copper-bearing pine tree (Pinus halepensis) from archeology in the copper mine in Cyprus. The wood contains brightly colored copper grains and copper pieces. The tree is about 2500 years old and the copper mine is the site of 18 ~ 14th century before the era.
