GUID (UUID V4):

Porphyry copper-gold ore field in southeastern Mongolia, close to the Chinese border. Perhaps the world's largest agglomeration of copper and gold deposits.

The site was discovered in 2001 and is being operated as a joint venture between Turquoise Hill Resources (a majority owned subsidiary of Rio Tinto) with 66% ownership and the Government of Mongolia with 34%.

The ore field contains four large deposits and several occurrences within a 7 km long belt.
