China Unveils Massive Gold Reserve: Liaoning’s Dadinggou Mine
On November 14th, China’s Ministry of Natural Resources announced a groundbreaking discovery: the Dadinggou gold mine in Liaoning province. This low-grade but colossal deposit boasts a staggering 1,444.49 metric tons of proven gold reserves, making it the largest single gold mine found since the founding of the People’s Republic of China.
The Dadinggou mine holds 2.586 billion tons of proven gold ore at a depth of -720 meters, with an average grade of 0.56 grams per ton. Despite its low grade, the sheer volume of ore positions this mine as a cornerstone in China’s strategy to bolster its national gold reserves.
This discovery follows a string of significant finds in the North China Craton belt and the Zhejiang-Fujian region. The Dadinggou mine has completed its feasibility study and is deemed highly promising for extraction.
Record-Breaking Exploration Efforts
The exploration process set a new benchmark for speed and scale. At its peak, nearly 1,000 engineers and workers were deployed alongside 45 drilling rigs operating simultaneously. The project utilized a “multi-tiered, closed-loop” management model, integrating central strategy, specialized execution, and continuous technical support.
The Liaoning Geological Exploration and Mining Group, granted exploration rights in late 2023, collaborated with 18 research and production organizations to launch a major campaign, employing cutting-edge technologies.
Over 15 months, the team drilled 219 boreholes totaling 136,700 meters, investing nearly 200 million yuan (approximately $28 million USD).
The Dadinggou mine holds immense significance for China, both economically and in terms of resource security. It strengthens the nation’s strategic gold reserves, enhancing its position in a volatile global gold market.
This discovery also revitalizes the gold industry in Liaoning, contributing to the broader revitalization of China’s Northeast, a traditional industrial hub prioritized for redevelopment by Beijing.
Furthermore, the find enriches geological knowledge, particularly in deep and peripheral exploration techniques for known resource deposits.
Initial indications of the mine’s existence date back to 1989, with further surveys in 2009 and 2014. However, the full extent of the deposit was only confirmed during the comprehensive 2023-2025 survey.
The discovery of this massive gold mine is a strategic milestone for China, as the nation accelerates its efforts to strengthen mining capabilities, innovate exploration technologies, and ensure long-term resource self-sufficiency.
