新华鲜报|千吨超大型金矿！“低品位”何以成利好？

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].
