Project Overview
项目概况
Tunnel exploration in this mine is composed of 4 main shafts about 4000 m long that are fully controlled along the vein, including for transverse drift, ore drift, ventilation and ore pass. A total of 5 ore bodies are delineated, including the large bodies No. 1, 2 and 3. Preliminary work and reserve reviews have been conducted on ore bodies No. 1 and 2. In total, 380,430 t of silver ore and 41,276 t of antimony ore are reported. Subject to the occurrences of ore, it is generally planned that the ore bodies No. 1 and 2 will be mined first and their reserves calculated to a high degree of specificity prior to the rest of the ore bodies. Controlled length of near surface parts of the ore bodies and the deep parts of 4-level veins is about 650m, and dip depth about 400 m, with the potential and grade increasing with the dip. Thickness ranges from 0.7 - 4.5 m with average thickness of 1.5 m, signifying a stable thickness. The 650 m long ore body is continuous along the vein, with a silver grade of 55 – 632 g/t (Avg. grade 308 g/t Ag), and an antimony grade range of 0.3 - 1.48% Sb. However, associated scheelite is found in all ore bodies, with mean tungsten grades ranging between 0.32 - 1% W, and maximum grade of local block tungsten as high as 73%. All ore bodies show an association of massive and stripped tungsten.
本矿主要以坑探为主，约4000m左右坑道施工 4个主洞口，上中下沿脉全控制，其中包括穿脉，沿脉，通 风，溜矿井等全部贯通。共圈出5条矿体，其中规模较大的 3条，编号1，2，3号，前期工作主要以1，2号矿体为主，参 与储量评审的为1，2号矿体，报告共提交银矿石量 380430t，锑矿石量41276t，根据矿体赋存状态。总体规划为 先开采控制程度较高，参与储量计算1.2.号矿体，其余矿体 后期开采，矿体地表及深部4层沿脉控制约650m，延深控制 约 400m，深 部 延 深 潜 力 明 显 变 厚，品 位 较 高，厚 度 0.7—4.5m，平均厚度1.5m，长度650m，银品位55—632×10^-6，平均308×10^-6，锑品位0.3-1.48%。矿体均共生白钨矿，呈 块状，条带状，平均品位0.32%-1%，局部块状钨精最高达 73%。
