Sumatra hits huge prized metals deposit

An Australian resources company has discovered a massive copper and gold deposit in Indonesia’s northern Sumatra that it says could rival Rio Tinto’s Bougainville deposit in Papua New Guinea, which was the world’s largest open-cut mine when it ceased operations in 1989.

Tigers Realm Group has identified a maiden resource of more than half a billion tonnes grading 0.47 percent copper. The Beutong deposit also holds gold and silver and has a higher-grade core of 153 million tonnes at 0.63 percent copper. The company has implemented a scoping study to investigate the viability of a mine at the discovery.
