Walegen
It is a large-scale Au deposit with proven and probable Au reserves of 38.51 t. Exposed strata in the district are mainly in the Longwuhe Formation and Quaternary sediments, which are exposed in the valleys. The exposed rocks in mineralized zones are mainly feldspar–quartz sandstone, quartz diorite, and plagioclase granite porphyry with zircon U-Pb ages of 228.2 ± 1.9 Ma. There are seven Au mineralized alteration zones hosting thirty six gold ore bodies in the mining area. The ores can be divided into sandy slate cataclasite-type, fine-vein disseminated quartz porphyry, and stibnite vein-type ore.
