Chinese scientists have uncovered a “supergiant” deposit of high-quality gold ore hidden near some of the country’s existing gold mines. The vast reserve, which could be the largest single reservoir of the valuable metal left anywhere on Earth, could end up being the largest known deposit of the precious metal anywhere in the world, and is worth more than $80 billion.

As LiveScience reports, the new deposit was uncovered at the Wangu gold field in the northeast of Hunan province, representatives from the Geological Bureau of Hunan Province (GBHP) told Chinese state media on Nov. 20. Workers detected more than 40 gold veins, which contained around 330 tons (300 metric tons) of gold down to a depth of 6,600 feet (2,000 meters). However, using 3D computer models, mining experts have predicted that there could be up to 1,100 tons (1,000 metric tons) of gold — roughly eight times heavier than the Statute of Liberty — hidden at depths of up to 9,800 feet (3,000 m).

If true, the entire deposit is likely worth around 600 billion yuan ($83 billion), GBHP officials said.
