Geologists in China have discovered a “supergiant” gold deposit in the Wangu goldfield, Hunan Province, potentially holding over 1,000 tonnes of gold, valued at around $80 billion and featuring exceptionally high-grade ore with visible gold, marking a massive find that could be among the world’s largest and highest-grade discoveries, with development challenges due to its significant depth (up to 2,000-3,000 meters).
Key Details of the Discovery:
- Location: Wangu goldfield, Pingjiang County, Hunan Province, China.
- Estimated Size: Initial drilling confirms 300 tonnes, with geological models suggesting over 1,000 tonnes in more than 40 gold veins.
- Value: Approximately 600 billion yuan, or over $80 billion.
- Grade: Exceptionally high, with some samples showing 138 grams of gold per tonne of ore (commercial mines often below 10 g/tonne) and visible gold in core samples.
- Significance: It’s considered one of the largest and highest-grade gold deposits ever found, potentially surpassing older records.
Discovery & Future:
- Method: Advanced 3D geological modeling and deep drilling (around 2,000 meters) were crucial in locating the deposit.
- Challenges: Mining at such depths (up to 3,000 meters) presents significant costs, technical hurdles (pressure, heat, groundwater), and a lengthy development timeline (10-20 years).
- Next Steps: China will conduct further drilling and feasibility studies before full development.
This “supergiant” find is a major geological event, potentially reshaping China’s gold reserves and offering substantial resources despite the considerable mining challenges.
