4. Deposit characteristics
Copper ore bodies, distributing along both wings of Sigou anticline, present in the phyllite of Hengguanling Formation, genetically is sedimentary metamorphic. There are 12 ore bodies in this area, the 2# and 3# ore are main ones. The 2# ore distributes between line3 and line9, existence elevation is 800-600m, stretches 600m long and 150m deep, occurs as stratified beds with average thickness of 5.2m, simply shaped and has the same occurrence with strata. Currently, the 2# ore is controlled by ZK301 and ZK701 with project interval of 200m. The 3# ore distributes between line3 and line7, existence elevation is 800-680m, stretches 200m long and 120m deep, occurs as stratoid beds or lens, simply shaped, with average thickness of 4.3m, and has the same occurrence with strata. The 3# ore is controlled by ZK303 and ZK502 with project interval of 200m.
Industrial type of the ore is metamorphic stratified copper mineral. Mineral of the ore is mainly chalcopyrite, then malachite, and few linnaeite, other metallic mineral is dominantly pyrite. Vein minerals are sericite, quartz, biotite, secondary are muscovite, garnet, hornblende et al. And the main texture is metasomatism dissolution texture, then solid solution separation texture.  Chalcopyrite is mainly presented as xenomorphic granular, with diameter of 0.1-0.3cm, and the ore structure is dominated by fine vein shape, dispersion shape, disseminated shape, and then the massive type.
Mean grade of the Cu in the ore is 0.64%, generally 0.51-0.82%. Other helpful element is low grade Co, 0.0046%. No harmful element was yet found.

5. Technical processing properties of ore: ore discovered from pitting was prepared in small preparation plant. The discovery is 90%, and the grade of the concentration is 20%. So, the ore is easily to be prepared.

6. The hydrology and engineering geology is simple in this mining area.

4、矿床特征
       铜矿体赋存于横岭关组千枚岩中，分布于寺沟背斜两翼，成因类型为沉积变质型。区内共有矿体12个，主要为2、3号矿体。2号矿体分布于3线-9线之间，赋存标高800-600米，矿体延长600米，延深150米，呈似层状产出，形态简单，矿体平均厚度5.2米，产状与地层一致，目前由ZK301和ZK701控制，工程间距200m，3号矿体分布于3线-7线之间，赋存标高800-680米，延长200米，延深120米，似层状或透镜状产出，形态简单，平均厚度4.3米，产状与地层一致，由ZK303和ZK502控制，工程间距200m。
矿石工业类型为变质岩层状铜矿。矿石矿物主要为黄铜矿，孔雀石次之，偶见硫钴矿，其他金属矿物主要为黄铁矿。脉石矿物有绢云母、石英、黑云母，次为白云母、石柳石、角闪石等。矿石以交代溶蚀结构为主，次有固溶体分离结构，黄铜矿多呈他形粒状，粒度0.1-0.3厘米，矿石构造以细脉状、散点状、浸染状为主，次主团块状。
矿区矿石铜平均品位0.64%，一般为0.51-0.82%，矿石中有益元素还有钴，品位较低，为0.0046%。未发现其他有害组份。

5、矿石技术加工性能：根据坑探中回收的矿石在个体小选厂加工情况，回收率为90%，精矿品位为20%，应属易选矿石。

6、矿区水文地质、工程地质条件为简单型。
