The principal exposed strata are the Paleocene–Eocene Pana and Nianbo formations of the Linzizong Group, which generally dip to the northwest. The Nianbo Formation, exposed mainly in the central–southern and northwestern parts of the area, consists of rhyolitic crystal tuff, rhyolitic lithic–crystal tuff, and purplish-red volcanic breccia, and is conformably overlain by the Pana Formation. The Pana Formation, exposed chiefly in the central–eastern and southern parts of the area, is composed primarily of dacitic crystal tuff and dacite. Magmatic rocks are limited and occur mainly as late-stage dikes, including granite porphyry, diorite porphyry, and lamprophyre. One Cu and one W mineralized body have been delineated in the Zhigunong mining area. The Cu body, located in the eastern part of the area, is ~570 m long and 200–220 m wide, occurs at depths of 73–132 m, strikes northwest, and shows a crescent-shaped plan geometry. The W body is spatially associated with the Cu body, extends for ~200 m, and is buried at a depth of ~210 m. The host rocks are mainly dacitic crystal tuff, with tungsten occurring predominantly as scheelite.
