China’s geological authorities are examining very large gold deposits found in the country's northeast and central areas. The Dadonggou deposit in Liaoning and the Wangu deposit in Hunan have drawn renewed focus after years of exploration. Early estimates suggest Dadonggou contains more than 1,000 tonnes of gold at about 3,000 meters depth. This resource is valued at roughly 600 billion yuan ($83 billion), though these numbers are preliminary and need more verification. The Dadonggou deposit is unusual because it has low-grade gold spread evenly in a large area, rather than high-grade veins. Gold levels range from 0.3 to 1.0 micrograms per gram. Its unique geology involves broad shear zones and layered changes, a style now called "Dadonggou-style" by some geologists. Nearby, the Wangu deposit in Hunan could bring total gold resources in these two sites to over 2,000 tonnes. This may be the biggest combined gold discovery in China recently. However, experts remind us that early estimates often shrink once mining costs, technical limits, and environmental concerns are considered. Though low in grade, Dadonggou’s ore is shallow and appears easy to process, which can help offset costs. Researchers emphasize caution, saying that gold underground does not automatically mean gold mined. The deposit is currently more valuable for what it reveals about gold formation than immediate mining profits. The discoveries spark fresh interest in China's gold geology and mining landscape, but actual extraction and economic returns remain to be proven in the future.
