Bismuthinite
Formula: Bi2S3
Description: Although bismuthinite has been reported in older references by Chinese authors, alleged silvery fibrous and acicular "bismuthinites" from here usually turn out to be stibnite on analysis (Jensen, 2009). Antimonian bismuthinite was found by Bart Cannon Microprobe Company on a Saul Krotki specimen.

Bismutite ?
Formula: (BiO)2CO3
Description: Probably mis-identified and actually an alteration product of stibnite. Considering that Jensen (2009) could not confirm any independent bismuth minerals on contemporary specimens, the presence of bismutite appears very doubtful.
Reference: Jensen, M. (2009): Mineral News 25(4), 1-11, 14

Formula: Cu5FeS4
Description: Perhaps a mistaken ID of blue-tarnished sphalerite (Jensen, 2009)

Boulangerite
Formula: Pb5Sb4S11
Habit: Acicular fibrous crystals to 12 cm
Colour: Metallic silvery gray
Fluorescence: Not fluorescent

Freibergite
Formula: Ag6[Cu4Fe2]Sb4S13-x

Galenobismutite
Formula: PbBi2S4
Description: This mineral has been reported from the vein-type ore bodies (Chen, 1981). However, all traded specimens of alleged silvery fibrous and acicular "galenobismutite" that have so far been analyzed turned out to be stibnite or one of the sulfosalts. According to Jensen (2009), analyses of a large number of samples from all levels of the mine never disclosed the presence of any bismuth bearing minerals. These findings do not necessarily discredit all earlier reports, since it has to be kept in mind that all parts of the deposit were mined long before the first specimens appeared on the western market in the early 1990s, that mineralization zoning is a common phenomenon in intrusion-related deposits, and thus a different mineral assemblage may have been found in parts that are now mined out. They indicate however, that bismuth minerals are rare at this locality, if they can still be found at all.

Formula: Ag2Te
Reference: Weining Zhou (1994): Mineral Resources and Geology 8(4), 233-244
Hübnerite
Formula: MnWO4
Description: Data presented by Chen (1981) show a significant excess of manganese over iron (Fe:Mn ranging from 1:4 to 3:4) in all analyzed samples of wolframite from the vein-type ore bodies. Likewise, the samples from the quartz vein ore bodies used in the study by Cao et al. (2009) have been shown to be hübnerite. Ottens and Cook (2005) however state that wolframite is predominantly ferberite and hübnerite was only found in one single pocket, suggesting that their samples came mainly (all ?) from the skarn-type ore bodies.
