黑龙庙矿床为以金为主的金银铜多金属矿床,通过对其区域成矿地质背景、成矿地质体(赋矿围岩)、矿体规模、矿石类型及其品位变化等特征的研究,发现该矿床矿体由表及里品位和厚度等分别呈现出变富和增厚的趋势;矿石自然类型有蚀变黑云二长花岗岩型和石英脉型两种,以前者为主。前期勘查和综合研究结果表明,此矿床具有较大的找矿潜力,通过进一步开展以中、深部探矿为主的地质工作,可大幅度提升区内已探明的Au、Ag、Cu等金属矿产的资源/储量,有望圈定和提交中-大型以金为主的多金属矿产地一处。
黑龍廟礦床為以金為主的金銀銅多金屬礦床,通過對其區域成礦地質揹景、成礦地質體(賦礦圍巖)、礦體規模、礦石類型及其品位變化等特徵的研究,髮現該礦床礦體由錶及裏品位和厚度等分彆呈現齣變富和增厚的趨勢;礦石自然類型有蝕變黑雲二長花崗巖型和石英脈型兩種,以前者為主。前期勘查和綜閤研究結果錶明,此礦床具有較大的找礦潛力,通過進一步開展以中、深部探礦為主的地質工作,可大幅度提升區內已探明的Au、Ag、Cu等金屬礦產的資源/儲量,有望圈定和提交中-大型以金為主的多金屬礦產地一處。

Heilongmiao deposit is an altered rock typed gold-silver-copper polymetal deposit with gold as its main mineral. Through research on regional metallogenic geologic context,metallogenic geologic bodies(ore-bearing wallrock), ore-body scale,ore types and grades variation,it is found that the ore grade and thickness of ore-bodies increase from the outer part to the inner part of the deposit. There are two natural types of ore,namely,altered biotite monzonitic granite typed ore and quartz vein typed ore,the former as main type. Based on the preliminary prospecting result and comprehensive study,it is concluded that this deposit has a promising prospecting potentiality. Through further exploration mainly consisting of medium to deep geological prospecting,the measured reserve of Au,Ag,and Cu in the mining area can be largely increased and a medium-scaled gold-dominated polymetal deposit can be delineated and obtained.
