A quartz gangue with some primary and secondary minerals has recently been studied and described from the Sn-W deposit Cínovec. This gangue with sulfides is accompanied with stolzite, cerussite and native silver (Trangot shaft, 3rd level, Militarschacht), and a tennantite mineralization with kankite and pitticite was identified in the material examined (Petra shaft, 2nd level). Abundant crystals of cerussite as much as 4 cm in size accompanied by wire native silver were not yet described in this deposit. The assemblage of secondary minerals comprises pitticite and kaňkite. The Sn-W deposit Cínovec is the eight locality in the Czech Republic where the latter mineral was described from. The secondary minerals are evidently products of weathering of tennantite and pyrite.
