Abstract
Small pyrometasomatic ore bodies contain massive sulfide, mainly sphaleirte and pyrite, with minor chalcopyrite, galena, arsenopyrite, magnetite, hematite, chlorite, calcite, garnet, and sphalerite Gold, silver, zinc, copper, lead, sulfur, and cadmium are recovered. The tellurides altaite, hessite, petzite, and sylvanite are scattered through the sulfides and gangue minerals. Free gold occurs in pyrite and the telluride minerals. The ore occurs as veins and pods, mainly along contacts between diorite porphyry dikes and limestone; a few veins are entirely enclosed within the limestone. The diorite porphyry is regarded as the source of the ore.
