堡子湾金矿位于华北地台北缘天镇断拱东部阳高凸起区，是与印支末—海西期火山—次火岩有关的隐爆角砾岩型金矿床。成矿物质主要来自重熔型岩浆源—石英二长（斑）岩，隐爆角砾岩为容矿岩石，与隐爆带总体走向平行的张扭性断裂为导矿构造，隐爆角砾岩的内部裂隙及角砾间隙，是良好的储矿构造。中生代火山、次火山机构是找矿的构造标志，金银砷元素组合异常是地球化学标志，铁帽是地表直接找矿标志
The Baoziwan gold deposit is located in the Yanggou bulge in the eastern part of the Tianzhang fault arch in the northern margin of the North China Platform and is a cryptoexplosive breccia type gold deposit associated with the Indosinian-Hercynian volcanic-secondary rock. The ore-forming materials mainly come from the remelting magmatic source-quartz two-plagioclase rock, cryptoexplosive breccia as ore-bearing rocks, and the tensile and torsional fractures parallel to the general strike of the implosive zone are the ore-bearing structure, crypto-explosive breccia The internal rock fracture and breccia gap, is a good reservoir structure. The Mesozoic volcano and sub-volcano are the tectonic markers of prospecting. The anomaly of arsenic and arsenic is a geochemical indicator, and the iron cap is a direct indicator of the surface prospecting
