四川九龙中咀铜矿床为近年来新发现的一个产于江浪变质核杂岩中的富铜矿床。矿体呈似层状，受韧性剪切带控制，矿体在走向和倾向上延伸稳定。主要矿石类型为浸染状、网脉状、角砾状、块状铜锌矿石。矿石建造为Fe-Cu-Zn建造。金属矿物由黄铜矿、磁黄铁矿、闪锌矿、方铅矿等组成。主要蚀变类型为石榴子石化、绢云母化、绿泥石化、黑云母化。矿体铜品位较高，平均品位为1．65%。目前该矿床仍在进行详查地质工作，矿区向东和向北西方向仍具有较好的找矿前景。该矿床的发现与评价，对于重新认识里伍铜矿床外围找矿潜力和进一步指导该区找矿工作具有重要意义。

The Zhongzui Copper deposit, a medium-sized copper-rich deposit explored in recent years, is hosted to the Jianglang metamorphic core complexes in Jiulong, western Sichuan. The copper ore bodies often occur as stratoids controlled by ductile shear zones, and are laterally extensive. The ore types comprise disseminated, veinlet, brecciated and massive Cu-Zn ores in the Fe-Cu-Zn formations. The metallic minerals contain chalcopyrite, pyrrhotite, sphalerite and galena. The main alterations include garnetization, sericitization, chloritization and biotitization. The ore bodies have higher copper grades, with an average copper grade of 1. 65%. The discovery of the Zhongzui copper deposit is significant to the reassessment of the exploration potential around the Liwu copper deposit.
