Beijing A multi-metal mine in resource-rich Tibet has been found to have the potential to be one of the world's 50 biggest mines of its kind that could generate an annual product value of USD 712 million from 2015.

The mine located in the birthplace of Tibetan King Songtsen Gampo about 68 kms from provincial capital Lhasa may become the country's biggest copper town in 10 years, Jiang Liangyou an official of Tibet Huatailong Mining Development said.
