中文摘要: 菲律宾远东南铜金矿床是一个产于石英闪长岩和火山碎屑岩中的斑岩铜金矿床,1980年至1994年矿床勘探采大致用75 m×100 m网度对矿体进行了控制,求得了一定的探明和控制的资源量。NERIN由于项目可行性研究的需要,采用地质统计学重新估算了资源,经与各家公司估算结果对比,差异不大,说明估算结果可靠。最后按照中国的勘探类型,根据矿床控制程度对资源进行了分类。该矿床的地质统计学资源估算方法作为一个案例值得矿床资源估算中研究推广。
Abstract:Far Southeast Copper-gold deposit in Philippines was a gold-rich porphyry copper deposit hosted by an ovoid quartz diorite porphyry stock which intruded a volcaniclastic sequence, definite measured and indicated resource was defined with the exploration grid 75 m×100 m during deposit exploration from 1980 to 1994. The resource was estimated by several corporations. In order to meet the need of feasibility study, the resource was estimated again with geostatistics method by NERIN, and the estimated result was little different from those by the other corporations, which indicated that the estimated result was credible. Finally the resource was classified as measured and indicated according to the exploration works by exploration category. The case with geostatistics method was worth to be applied for deposit.
