Medium-sized granitoid-related vein-type gold deposit, located in a NW-trending belt that is 70 km long and contains several tens of mineralized and altered zones of up to 3 km length and up to 400 m width. These zones are veined ore elongated lenses, concordant to the host strata, or having small angles of 5-15°. The ores have veinlet-disseminated, or veinlet-stockwork structures and are of idiomorphic-hypidiomorphic, inclusive and caulking textures. The host strata are composed of tuff, Middle Devonian tuffeous breccias of andesitic-basaltic composition, sandstone, siltstone, mudstone, and locally Upper Devonian andesite, rhyolite and trachyte. Host rocks for gold, or related to gold mineralization also include biotite granite, granodiorite, potassic granite, granite porphyry, quartz porphyry, diorite and diorite porphyrite.
