Core Viewpoint - The recent exploration project in Mao Wan Li manganese mine in Sichuan has discovered a significant manganese resource of 606.7 million tons, marking a breakthrough in the region's mining potential [1][2]. Group 1: Manganese Resource Discovery - The Mao Wan Li manganese mine exploration project has confirmed an inferred resource of 462.8 million tons within the surveyed area and an additional 143.9 million tons in the adjacent unclaimed area, totaling 606.7 million tons [1]. - The project has successfully identified over 600 million tons of manganese resources within just 1 square kilometer, indicating a medium-sized ore body and resolving a long-standing issue in the research of manganese resources in Northwest Sichuan [1][2]. Group 2: Geological Insights - The exploration has revealed that the Cambrian Qiu Jia He formation exhibits a multi-layered and interactive rhythm of manganese ore distribution, challenging previous assumptions about the small scale of "stone dam" type manganese ore bodies [2].
