Detailed mineralogical studies resulted in the identification of Pt-Pd-As-Te mineralization. It is represented by an assemblage of sperrylite, unnamed Pd tellurides, melonite, an unnamed Sb-Ni telluride, altaite and native gold. Besides pyrrhotite, chalcopyrite, pyrite, ilmenite, rare pentlandite, polydymite, arsenopyrite, sphalerite and cubanite, other ore minerals like violarite, pentlandite, galena, cobaltite, scheelite and baddeleyite were newly identified by Vavřín and Frýda (1998). It is very likely that the Pt-Pd-As-Te mineralization represents the latest stage of magmatic mineralization processes which resulted partly in remobilization of Ni-Cu magmatic ores and also in the formation of hydrothermal Pt-Pd-As-Te phases. This scenario is supported by the presence of thin sulfidic veins accompanied by carbonate, quartz and near ore alterations. The following mineral phases were investigated:

Low–intermediate sulfidation mineralisation was first documented in the area near Two-Thirty by B. M. Jones (1991), who described three types of auriferous veins crosscutting skarn and associated with fault zones. These veins are broadly correlated with Stage 3B veins from this study. Jones (1991) describes cockade veins associated with quartz–sericite–pyrite alteration. Base-metal sulfides are the dominant sulfide species with local inclusions of altaite in galena and chalcopyrite in sphalerite. Intergrowths of hessite and altaite are common with lesser chalcopyrite and tennantite and minor petzite and bornite, free Au occurs as inclusions in all sulfide and telluride phases, and is rarely observed as rims to pyrite grains (B. M. Jones, 1991).
