摘　　要：老挝班康姆铜金矿位于琅勃拉邦―黎府铜金多金属成矿带,属火山岛弧环境,受隐伏斑岩、矽卡岩和断裂构造控制。通过地球物理、地球化学等综合找矿信息的提取,提出3个找矿靶区和4个找矿预测区,新发现3个铜金矿(化)体,找矿实现了重大突破,矿床规模达到大型,预测金资源量大于50t,铜资源量大于6万t。Pangkuam Cu-Au deposit,lying in Luang Prabang-Loei Cu-Au polymetallic metallogenic belt,oc-curred in the volcanic island arc environment and was controlled by concealed porphyry,skarn and faulted structure.Through the extraction of comprehensive information of geophysical and geochemical prospection, this paper proposed three prospecting targets and four prospecting prognosis area.Three new Cu-Au mineral （mineralized）ore-bodies were discovered and the discovery realized important break through in prospection. The deposits reached large scale and the predicted amount of gold resource was greater than 50t while that of copper resource was greater than 60,000t.
