甘肃一地发现大型金矿

Core Viewpoint - A large gold mine has been discovered in the Qianhongquan area of Yumen City, with an additional gold resource of over 40 tons, equivalent to the resource amount of two large gold mines [1][2]. Group 1: Discovery and Significance - The newly discovered Qianhongquan gold mine adds over 40 tons of gold resources, significantly enhancing the region's mining potential [1][2]. - Gansu Province ranks second in gold resource reserves in China, with the Beishan mineralization belt being a key area for gold deposits [2]. - The discovery is a result of a long-term geological survey initiated in 2017, which laid the groundwork for identifying mining potential in the area [2][3]. Group 2: Exploration Efforts - The Gansu Geological Exploration Bureau's Fourth Geological Exploration Institute conducted extensive sampling and analysis, collecting 6,177 sediment samples and identifying 16 comprehensive anomalies with gold as a primary indicator [2]. - The exploration efforts included expanding the mineralization zone to 10 kilometers and identifying multiple gold bodies with industrial-grade ore [2]. - A total of 76.28 million yuan was invested in the Qianhongquan gold mine survey project, which involved significant drilling and exploration work, leading to the identification of a new mineralization belt approximately 14 kilometers long and 10-100 meters wide [2]. Group 3: Methodology and Future Implications - The discovery utilized large-scale geochemical exploration methods, providing valuable insights for future gold exploration in similar geological settings [3]. - The findings are expected to guide further exploration efforts in the Gansu North-South belt, particularly in selecting exploration methods and refining mining strategies [3].
