内蒙古李清地铅锌银多金属矿危机矿山找矿突破与找矿方向探讨

李清地铅锌银矿床位于内蒙古中部,经过多年开采,矿山已面临资源匮乏的危机。2018年至今,国城矿业联合有色地调中心和中色地科等地勘单位在该区开展系统的边深部找矿工作。对该区域及矿区地质特征、矿化体特征进行分析,对近两年来所开展的覆盖全区的地质、物化探工作和近万米钻探工作成果进行研究应用,探获的铅、金和银资源储量规模都达到了中型(铅锌25万t,银260t,金6t),估值超过70亿元,属于富铅锌(共生金银)矿,实现找矿重大突破。此外,该区域还发现了富钼工业矿体,从已获取的更多找矿信息可推断,李清地矿区还具有探获大型以上的富铅锌、金、银和钼矿的找矿远景。在该区运用火山-岩浆成矿系统理论指导,采取地质综合手段寻找深部成矿岩体,是李清地本轮找矿获得实质性进展的关键,也为今后该矿区找矿指明了方向。

Breakthrough and prospecting direction of the lead zinc and silver polymetallic deposit in Liqingdi crisis mines, Inner Mongolia

Liqingdi lead zinc and silver deposit is located in the central part of Inner Mongolia. After years of exploration , the mine is facing the crisis of lack of resources . Since the begining of 2018, Guocheng Mining has employed geological exploration units to carry out prospecting work at the edge and deep. Based on the analysis of the geological characteristics and mineralized body characteristics of the area and the mining area, and the comprehensive study of the geological, geophysical and geochemical survey and the drilling results of nearly ten thousand meters in the past two years,a major breakthrough has been made in this area recently, the new discoveries reserves and resources of the (rich) lead , gold and silver are achieved medium-size respectively , further more, rich molybdenum ore bodies are discovered, with the above mentioned, indicated that Liqingdi has a huge potential in prospect and may discovery rich Pb, Au, Ag and Mo deposits with the large-scale size or even above. Guided by the theory of volcano-magmatic metallogenic system, and a comprehensive geological method is adopted to find the deep ore-forming rock mass, is the key to the breakthrough of the prospecting,and it points out the direction for the ore prospecting in this area in the future.
