On November 14, Red Star News reporters learned from the Ministry of Natural Resources that Liaoning Province has successfully identified the first domestic kiloton - scale, low - grade super - large gold deposit - the Dadonggou Gold Deposit (with a cut - off grade of 0.25 grams per ton). At present, the economic feasibility of the deposit's development and utilization has been demonstrated, and the expected benefits are promising.

At present, the mine has passed the economic demonstration of exploitation and utilization, and the expected benefits are good. It is reported that in December 2023, Liaoning Provincial Geological Prospecting and Mining Group Co., Ltd. obtained the "Liaoning Province Gaizhou City Dadaogou Gold Mine Prospecting Prospecting Right". On September 15, 2025, the exploration report was reviewed and filed by the Liaoning Provincial Department of Natural Resources, and a total of 2.586 billion tons of gold ore and 14,444.49 tons of gold metal were explored above the elevation of -720 meters in the whole area, with an average grade of 0.56 grams / ton, and the ore body was located between the elevations of -913.06 meters and 115.08 meters, with a maximum strike length of 3,128 meters. It is the largest single gold ore body discovered since the founding of New China.

It is reported that the Liaoning Provincial Geological Prospecting and Mining Group has raised nearly 200 million RMB in its own funds, and after 15 months of exploration work, 219 boreholes have been completed, the mechanical rock core drilling advance has reached 136,700 meters, and the field work was fully completed on June 30, 2025. On August 19, the "Liaoning Province Gaizhou City Dadaogou Mine Area 34-39 Exploration Line Gold Mine Exploration Report" was submitted, creating a precedent for "short cycle, high quality" gold mine exploration in China.

The Ministry of Natural Resources introduced that the gold mine was first discovered in 1983, and made phased progress in the comprehensive prospecting work in 2009 and 2015. In 2024, a new round of exploration implemented the "comprehensive detailed exploration" exploration mode, and organized 18 production and research units to carry out a "big battle".

During the peak construction period, 45 drilling machines were operating simultaneously on site, and nearly a thousand staff members were working together. The three-dimensional modeling technology was fully applied to show the state of the ore body, and the geological statistical method was used to estimate the resource volume. After verification by the traditional geometric method, the estimated results were true and reliable.

The Ministry of Natural Resources said that the implementation of the project not only further consolidates the national strategic reserve of gold resources, but also provides a successful example for the deep and peripheral mineral exploration of the original resource base, significantly enriching the gold mine genetic theory, and is of great significance for creating a world-class gold industry base in Liaodong and serving the comprehensive revitalization of Northeast China.
