Ore minerals and sulfides in the vein include freibergite, pyrite, chalcopyrite, galena, and sphalerite. It occurs in hydrothermal deposits associated with sphalerite, pyrite, chalcopyrite, barite and marcasite. The ore minerals in order of decreasing abundance are sphalerite, chalcopyrite, and galena. Its associated minerals include pyrite, chalcopyrite, quartz, anhydrite, fluorite, and scheelite. Pyrite, chalcopyrite and magnetite are typically found in higher abundances. Below that cap is a supergene zone containing pyrite, chalcopyrite, and sphalerite. Small amounts of pyrite, sphalerite and exsolved pentlandite and chalcopyrite are present with the pyrrhotite. The ore was chalcopyrite with pyrite and pyrrhotite in sericite schist host rock. Other products from the mine are sphalerite, chalcopyrite, and galena. Other products from the mine are chalcocite, chalcopyrite, galena, and sphalerite. Copper ore is present as chalcopyrite and tetrahedrite. Accessory and alteration minerals include hornblende, biotite, apatite, pyrrhotite, chalcopyrite, serpentine, chlorite, and calcite. Crystallographically the structure of chalcopyrite is closely related to that of zinc blende ZnS (sphalerite). It occurs as segregation deposits in layered intrusions associated with pentlandite, chalcopyrite and other sulfides. Associated minerals include&colon; arsenopyrite, barite, silver, cobaltite, pyrrhotite, pentlandite, chalcopyrite, breithauptite and maucherite.
