The largest gold mine in the world with 1,100 tons has been discovered in China

According to Chinese state media, a team of geologists detected over 40 gold veins of roughly 330 tons of gold ore dipping 6,600 feet deep under Pingjiang County’s Wangu gold field.

But 3D modeling blows that number out of the water, showing there could be as much as 1,100 tons as deep as 9,800 feet. If the models are accurate, the deposit in its entirety could be worth roughly $83 billion.

According to the report, the new discovery features 138 grams of gold per metric ton of ore, a valuable rate not often found in gold mining. “Many drilled rock cores showed visible gold,” said Chen Rulin, an ore-prospecting expert at China’s Hunan Province’s Geological Bureau, according to Chinese state media.
