Cu-Zn-bearing veinlets and dolerite dikes traversing Pb-Zn-bearing skarn formed from impure Mn-bearing Miocene limestone. The limestone bed is sandwiched between propylitized Miocene pyroclastics and andesitic or rhyolitic breccia. The skarn body itself was worked as Pb-Zn ore; the younger dolerite dikes as rich Cu-Zn ore.
