Core Insights - The Dadonggou gold mine in Liaoning Province has been identified as China's first thousand-ton, low-grade super-large gold deposit, with a resource amount of 1,444.49 tons, which could significantly alter the country's gold resource landscape [1][2]. Group 1: Economic and Strategic Importance - The large-scale nature of the Dadonggou gold mine allows for long-term stable mining, reducing reliance on high-grade scarce resources and enhancing national resource self-sufficiency [2]. - The mine's low-grade ore, with an average grade of only 0.56 grams per ton, can benefit from economies of scale, lowering unit costs and making the development economically viable through technological advancements in ore processing [2]. - The development of this mine is expected to generate substantial economic and social benefits, potentially decreasing dependence on imported gold [2]. Group 2: Historical Context and Development - The exploration of the Dadonggou gold mine has spanned over 40 years, with initial clues discovered in 1983 and subsequent surveys conducted in 2009 and 2015, culminating in the successful identification of the deposit in 2024 [4]. - The transformation of what was once considered a "waste mine" into a valuable resource highlights innovations in exploration concepts, mining technology, and environmental practices, providing a model for low-grade gold mining development in China [4]. - Future plans for the mine include integrating mining development with ecological restoration, aiming to promote local economic growth and rural revitalization during the 14th Five-Year Plan period [4].

Core Viewpoint - The successful exploration of the Dadongou gold mine in Liaoning Province marks China's first discovery of a thousand-ton, low-grade super-large gold deposit, which has the potential to significantly alter the country's gold resource landscape [1][2]. Group 1: Resource Characteristics - The Dandongou gold mine has a resource volume of 1,444.49 tons, making it the first single-unit gold mine in China to exceed a thousand tons [1]. - Despite its average grade of only 0.56 grams per ton, the mine's large scale allows for a cost-effective and sustainable mining approach, leveraging economies of scale and technological innovations [1][2]. Group 2: Economic and Strategic Importance - Gold is a strategic mineral resource crucial for national industrial and financial security, with China's gold mining industry characterized by a low proportion of large gold mines and a reliance on medium to low-grade deposits [2]. - The Dandongou mine's shallow burial and favorable local conditions (abundant water resources, well-developed electricity, and transportation networks) are expected to generate significant economic and social benefits, reducing dependence on imported gold [2]. Group 3: Development and Innovation - The exploration of the Dandongou gold mine took over 40 years, with significant milestones in 1983, 2009, and 2015, culminating in its recent successful identification as a valuable resource [2]. - The transformation of a previously shelved "waste mine" into a high-value strategic asset showcases innovations in exploration concepts, mining technology, environmental processes, and industrial development models, providing a Chinese solution for low-grade gold mining [2].

黄金是战略性矿产资源，对维护国家产业安全和金融安全具有重要意义。我国黄金资源大型金矿山 占比不足，已探明大型金矿多为中低品位，呈现"产销大国、储备中等"的行业特征。大东沟金矿矿体埋 藏浅、易开采，加之当地水资源充足、电力与交通网络完善，具备极佳的开发条件，将产生巨大的经济 和社会效益，一定程度降低对进口黄金的依赖。 大东沟金矿的勘探历经40多年。辽宁地矿集团地质勘查事业部部长白银增在接受新华社记者采访时 表示，该金矿床找矿线索于1983年首次发现，2009年和2015年，大东沟金矿项目又分别开展了两轮普查 工作。2024年开展新一轮勘查工作，最终成功探明我们国内首个千吨级、低品位超大型金矿床。 新华社北京11月14日电（记者王立彬）2025年11月14日，自然资源部宣布，辽宁省成功探明国内首 个千吨级、低品位超大型金矿床——大东沟金矿。 辽东一处寻常村落，隐藏着宛如巨龟的黄金矿脉，资源量达1444.49吨。这是我国首个单体千吨级 金矿，其规模足以改变国家黄金资源格局。 "超大型"好理解，"低品位"何以成为利好？答案在于规模效应与技术创新的双轮驱动。大东沟金矿 虽矿体平均品位仅0.56克/吨，从这个角度看，是名 ...
