After researching this claim, although there are not many sources that have put anything out there about this, but I did find a couple articles that talk about this.
My primary source that I found is from the New York Post titled " China claims to have unearthed the largest gold deposit in the world —worth $83B" https://nypost.com/2024/11/30/world-news/china-claims-to-have-unearthed-the-largest-gold-deposit-in-the-world-worth-83b/. The article is from 2024, and they claim that "China is claiming to have unearthed the largest gold deposit in the world — estimated to be worth more than $80 billion". I do notice that when talking about this they use words like "claim" and "alledged" when talking about the findings and mentioned that before this finding, the largest gold deposit was located in South Africa. It seems to me this is still being investiagted by scientists to confirm if this claim is true or not.
A second source I looked at is from https://www.popularmechanics.com/science/a70547429/china-supergiant-gold-mine-world/, "Geologists Might Have Stumbled Upon the Largest Gold Mine in the World". This article is pretty similar to the New York Post one, but it is mentioned that scientists only have a predicted amount of gold that they think is in the deposit, but it has not yet been confirmed. This article also uses language like "may have" and "claims".
Overall, I think this claim is misleading because it has not been confirmed that it is the largest gold deposit in the world, they are still investigating.
