1444.49吨！我国探明首个千吨级金矿

自然资源部14日公布一项重大找矿成果，由辽宁地矿集团在辽东地区成功探明了国内首个千吨级、低品位超大型金矿床——大东沟金矿，共探明金金属量1444.49吨，为新中国成立以来发现的规模最大单体金矿床。

The Ministry of Natural Resources announced on Friday a major mineral exploration breakthrough, as China has successfully delineated the first thousand-ton-level, low-grade super-large gold deposit — the Dadonggou Gold Mine — in the Liaodong region, Northeast China's Liaoning province, with a total proven gold metal content of 1,444.49 tons, making it the largest single gold deposit discovered since 1949, China Media Group (CMG) reported.

自然资源部表示， 大东沟金矿全区负720米标高以上共探明金矿石量25.86亿吨，金金属量1444.49吨，平均品位0.56克/吨。

The Ministry of Natural Resources said that the entire Dadonggou Gold Mine area above the -720-meter elevation has proven reserves of 2.586 billion tons of gold ore, with a total gold metal content of 1,444.49 tons and an average grade of 0.56 grams per ton, per the report.

自然资源部介绍，该金矿床找矿线索于1983年首次发现，在2009年和2015年的普查找矿工作中取得阶段性进展。2024年，新一轮勘查中创新实施“普详勘一体化”勘查模式，统筹组织18家生产与科研单位“大会战”。施工高峰期间，现场45台钻机同时运行，近千名工作人员协同作业。全面应用三维建模技术展示矿体赋存状态，采用地质统计学方法估算资源量，经传统几何法验证，估算结果真实可靠。

According to CMG, the Dadonggou Gold Mine is another super-large low-grade open-pit gold mine discovered in China. It has currently passed the economic feasibility assessment for development and utilization, with promising expected benefits. During the exploration process, nearly a thousand staff members collaborated on the work, shortening the exploration timeline to 15 months and pioneering a domestic precedent for "short-cycle, high-quality" gold mine exploration.

自然资源部表示，该项目的实施，不仅进一步夯实了国家黄金资源战略储备，也为原有资源基地深部及外围找矿提供了成功范例，显著丰富了金矿成矿理论，对打造辽东世界级黄金产业基地、服务东北全面振兴具有重大意义。
