Group 1 - Tungsten is a critical industrial metal, often referred to as the "tooth of industry," due to its exceptional hardness, high melting point, and significant density [1][3] - Tungsten alloys are widely used in military applications, including tank armor-piercing projectiles and missile warheads, as well as in aerospace components like rocket engine nozzles and turbine blades [3][5] - China holds over 50% of the world's proven tungsten reserves and accounts for 82% of global production, establishing a dominant position in the tungsten market [7][11] Group 2 - Chinese tungsten companies have shifted from exporting raw materials to producing high-value-added tungsten products, increasing their share in the global high-end market [9][11] - In 2023, tungsten was officially classified as a strategic mineral resource in China, leading to a 15% reduction in annual mining quotas to stabilize production at 140,000 tons [11][15] - The U.S. relies on imports for over 35% of its tungsten resources, with a 100% dependency on foreign sources for high-end tungsten products used in aerospace and military sectors [13][16] Group 3 - The U.S. has faced supply chain disruptions due to a shortage of high-end tungsten alloys, impacting production timelines for military equipment like the F-35 fighter jet and M1A2 tanks [16][18] - Major semiconductor companies, including Intel and TSMC, are experiencing tight supplies of precision tungsten wire, leading to a 40% price increase and production adjustments [18][20] - The U.S. government has initiated a "critical minerals strategy" with a budget of $3.5 billion for exploration and development of tungsten and other essential minerals [20][22] Group 4 - American companies are attempting to circumvent Chinese controls by sourcing tungsten through intermediaries in Vietnam and Mexico, but China's stringent regulatory framework complicates these efforts [24][25] - Data from Vietnamese customs indicates a 67% year-on-year decline in tungsten exports to the U.S. in the first half of 2024, highlighting the effectiveness of China's resource management policies [25][27] - China's strategic management of tungsten resources not only protects its limited resources but also ensures industrial security, presenting a sustainable model for global resource utilization [27]

锰矿，是一种重要的战略矿产资源，可以用于钢铁工业等领域。 记者近日从四川省自然资源部门获悉， 四川青川毛湾里锰矿普查项目取得重大突破，探获锰矿资源量606.7万吨。 经过长期勘探，毛湾里锰矿普查项目在普查区内探获锰矿石推断资源量462.8万吨，同时在该普查区与南邻采 矿权区之间的空白区估算锰矿石推断资源量143.9万吨，总计606.7万吨。值得注意的是，项目组在毛湾里仅1 平方公里就探获了超600万吨锰矿资源量，单矿体资源量规模达到中型，解决了困扰川西北锰矿区域研究50余 年的困惑和难题，提升了区域找矿空间。 四川省地质局第五地质大队队长 王晓辉： 通过毛湾里锰矿普查项目实施，证实寒武系邱家河组锰矿分布具有 多层多次交互式韵律产出特点，打破了对"石坎式"锰矿矿体规模较小的认识，在1平方公里上实现了探获锰资 源量606.7万吨。 来源：央视财经 END 校对： 杨立林 版权声明 证券时报各平台所有原创内容，未经书面授权，任何单位及个人不得转载。我社保留追 究相关 行 为主体法 律责任的权利。 转载与合作可联系证券时报小助理，微信ID：SecuritiesTimes 点击关键字可查看 潜望系列深度报道丨 股事会专 ...
