Geologists in China have uncovered one of Earth’s largest gold deposits beneath Hunan Province’s Pingjiang County, valued at €78 billion. The Wangu gold field holds over 1,000 metric tons of gold, according to the Hunan Geological Bureau, which confirms the deposit as a milestone for the global gold sector.
High-Yield Veins at Deep Earth Levels
Survey teams identified more than 40 gold veins at depths of around 2,000 metres, initially estimating 300 tons of reserves. Continued drilling at 3,000 metres increased the projected yield, surpassing 1,000 tons and confirming it among the world’s largest finds.

Experts noted the rare presence of visible gold in many extracted cores, indicating extremely high-grade mineralisation across key sections. Chen Rulin, ore-prospecting expert with the bureau, said, “Many drilled rock cores showed visible gold,” which reinforced the deposit’s exceptional yield.
Gold Density Shows Exceptional Concentration
Some ore samples contained as much as 138 grams of gold per metric ton, a figure rarely seen at such volumes. The high density strengthens the deposit’s commercial value, with analysts pointing to the rarity of large-scale sites yielding such concentration.
Advanced Modelling Key to the Discovery
The Hunan Geological Bureau relied on advanced 3D geological modelling to guide drill operations toward the richest areas. These models helped researchers locate underground gold formations with precision and map complex structures at depth.
Liu Yongjun, vice head of the Hunan Geological Bureau, said, “Gold was also found during drills around the site’s peripheral areas,” indicating the deposit may extend further.

Potential for Expansion Beyond Current Estimates
Exploration efforts continue beyond the mapped zones, with the bureau expecting further discoveries around the Wangu site. Surrounding areas show similar geological signatures, suggesting the deposit may grow in size with ongoing drilling.
Economic Impact Spans Regional and National Sectors
The Wangu discovery positions Hunan Province as a central player in China’s gold production network. Industry observers expect strong domestic and foreign investment interest in the site’s development and processing capabilities.
Mining operations could generate thousands of new jobs and stimulate support sectors like transport, energy, and logistics. Infrastructure upgrades will be necessary to handle the extraction and movement of heavy ore across the region.
Boost for China’s Strategic Gold Reserves
The deposit strengthens China’s position in the global gold market, adding to its strategic reserves amid shifting economic conditions. Analysts estimate the site’s value at over 600 billion yuan, reflecting long-term benefits for national fiscal planning.
Environmental Oversight Needed for Large-Scale Mining
Industry leaders and environmental experts urge strict management of ecological risks linked to the deposit’s development. Key concerns include land degradation, carbon emissions, and water resource usage, particularly in high-yield zones.
Regulators must balance industrial growth with sustainability, as the scale of operations increases pressure on local ecosystems and communities.

A Global Case Study in Resource Development
The Wangu site represents a test case in combining economic opportunity with responsible mining practices. Authorities have emphasised careful monitoring to reduce environmental damage while securing long-term profitability.
Mining Sector Watches Development Closely
International mining corporations are tracking the Wangu project for potential partnerships and technology transfer opportunities. Analysts note the site’s strategic location and high-grade mineral content as key attractions for future investment.
Exploration Success Reflects National Strategy
China’s push for high-tech geological exploration is delivering results, with Wangu serving as proof of its capabilities. Officials see the deposit as a major achievement in resource prospecting, backed by innovation and precise modelling.

Gold Industry Set for Global Adjustment
The Wangu discovery may shift gold production forecasts and influence international pricing strategies. Supply chain planning will adjust to accommodate the influx of high-quality reserves from the new site.
Outlook Tied to Responsible Development
The discovery offers economic benefits but requires careful oversight to meet both market and environmental expectations. Industry participants await further updates as exploration and planning continue in Pingjiang County.
