摘　　要：永善金沙厂铅锌矿是一座开采历史悠久的老矿山,具备大型铅锌矿远景资源前景。依据成矿地质条件和综合矿化信息,结合以往勘查资料及成果,应用综合信息法、多成因类型矿床预测法和趋势外推法确定1个一级找矿靶区和2个二级预测找矿靶区,初步预测Pb+Zn金属资源量达20万吨,为矿区可持续发展提供远景资源条件。Jinshachang Pb-Zn Deposit is an old mine with very long exploitation history,having resource potentiality of large scale Pb-Zn deposit.According to the geological condition and comprehensive information of metallogenesis and in combination with the past exploration data and result,utilization of comprehensive information method,prognosis method of multi-genesis type deposit and trend extrapolation method,a 1-class prospecting target and two 2-class prognosis prospecting target have been determined,with preliminary prognosis Pb+Zn resources 200000t,providing the potentiality resource for the sustainable development of the orefield.
