四川探获最大金矿 资源量超80吨

Core Viewpoint - Sichuan Province has made a significant breakthrough in gold mining exploration with the discovery of the Dongbeizhai gold deposit, which has been evaluated to contain an additional gold resource of 28.24 tons, bringing the total confirmed gold resource to 81.06 tons, marking it as the largest gold mine in Sichuan to date [1] Group 1: Exploration and Findings - The Dongbeizhai gold deposit has been classified as a super-large scale mine with an average gold grade of 3.75 grams per ton [1] - The exploration work was conducted by the 10th Geological Brigade of the Provincial Geological Bureau, involving nearly 100,000 meters of drilling and over 4,000 meters of tunnels, along with the collection of 35,000 samples [1] Group 2: Research and Development - In addition to exploration, the project has undertaken multiple specialized studies, including research on mineralization mechanisms and structural relationships, to establish a mining model for "Dongbeizhai-style" fine-grained gold deposits [1] - The project has also conducted beneficiation tests to overcome technical challenges related to high arsenic and high carbon gold ore, laying the groundwork for future development and utilization of the deposit [1] Group 3: Strategic Implications - The discovery of the Dongbeizhai gold deposit alters the traditional landscape of gold exploration and development in Sichuan, providing resource assurance for the establishment of a strategic gold mining base in the western Sichuan region [1] - This breakthrough significantly enhances Sichuan's strategic position in the national gold mining sector and offers valuable experience and demonstration for similar types of mineral exploration across the country [1]
