新华鲜报丨千吨超大型金矿！“低品位”何以成利好？

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].
