There are three genetic types of mineral deposits in the Beiya ore district:① Cu-Au polymetallic deposits related to alkaline porphyries, comprising porphyritic Cu-Au deposits and polymetallic skarn deposits related to quartz-albite porphyry and quartz-K-feldspar porphyry;② Fe-Au deposits related to gabbro or basalt magma, consisting of magmatic Fe-Au deposits and sedimentary polymetallic deposits formed in caves and lakes; and ③ palaeo-placers formed at the weathering surface, in lakes and in karsts.
北衙金矿有3种成因不同的矿床：①与碱性斑岩有关的铜金多金属矿，包括与石英钠长斑岩和石英正长斑岩有关的斑岩型铜金矿床和矽卡岩型多金属矿床；②与辉长－玄武岩浆有关的铁金矿床，包括熔浆型铁金矿床和喷流沉积型多金属矿床，后者又有洞穴和湖相沉积环境之分；及③古砂矿，有古风化壳型砂矿、河湖相古砂矿和洞穴沉积古砂矿。
