The exposed strata in the Huayagou area belong to the Devonian Hejiadian Formation of the Shujia’ba Group, comprising metasandstone, metasiltstone, slate, and quartz-chlorite schist. The rocks have undergone complex deformation, metamorphism and metasomatism. The breccia within the zones consists of fragmented sericite schist, cemented by siliceous, calcareous, argillaceous, and ferruginous materials. These zones exhibit a gently undulating wave-like structure along the dipping direction. In addition to these shear zones, a major SE-trending thrust fault, steeply dipping southward, has undergone significant alteration and brecciation, making it another critical control on mineralization. This fault zone, 50–200 m wide, intersects with a southward-trending fault, forming structurally favorable zones for gold enrichment at their intersections.

Huayagou ores are mainly disseminated, with minor sulfide-bearing micro-veins. Two mineralization stages are identified: an early quartz–sulfide micro-vein type, and a later disseminated type dominated by arsenopyrite and tourmaline.
In addition to the widespread occurrence of disseminated-type ores, quartz-vein-type ores have been identified in Jinchanggou. These ores are hosted within the same mineralized alteration zone (MAZ) previously described.

The Huayagou gold deposit is situated within the central segment of the Taiyangsi district, with documented gold reserves at 5.8 tons in the past decade. In 2024, the drilling engineering at Huayagou discovered two new orebodies, with estimated resource of 20 tons.
The Hejiadian Formation in the Devonian, the dominant host sediment sequence of orebodies, dominantly composed of metamorphosed metasandstone, metasiltstone, slate, and quartz-chlorite schist, all reached lower greenschist facies. The Huayagou gold deposit contains at least 10 Au orebodies. These orebodies strike 150°–180° and dip 60°–80°, with strike lengths ranging from 160 m to 400 m and widths from 30 m to several centimeters. Ore grades vary from 0.8 g/t to 24.3 g/t, with an average grade of 1.69 g/t. Average-grade ores typically occur as fine veinlets within interlayer fractures of the strata, whereas high-grade mineralization manifests as quartz-sulfide veins hosted in shear zones, appearing as brecciated ore at the surface.
