龙头山金矿床Au 9号矿体地质特征及资源/储量估算

摘要

Longtoushan gold deposit is a volcanic-subvolcanic hypothermal gold deposit where Au 9 gold ore body is newly delineated as low grade type.Based on previous exploration work and geological data of mining production,with tunnel exploration as a complementation,the form,occurrence,space locations as well as thickness and grade variation are detected.Besides,resource estimation of Au 9 ore body was conducted,the result indicated a reserve of gold 13 t,silver 167 t.%龙头山金矿床为火山一次火山热液型金矿床,Au 9号矿体为在龙头山金矿区新圈定的低品位金矿体.在以往地质勘查工作及矿山生产地质资料的基础上,通过补充坑道勘探工程,基本查明了Au 9号矿体的形态、产状、空间位置及厚度、品位的变化情况,并对Au 9号矿体资源/储量进行了估算,估算结果,保有储量:金金属量约13 t,银金属量约167 t.
