how much copper from million tons of ore

Papua Region's Copper Ore Reserve is Approximately 2.6

Copper ore reserve in Papua is estimated at 2.6 billion tons. Meanwhile, copper metal reserve is only about 25 million tons. Minerals and excavations that promise other potentials are nickel ore, iron sand, and gold. Nickel ore is found in Tanah Merah area, Jayapura. Most of these resources are still indications and are still unexploited.
