Pyrite-magnetite-chalcopyrite-sphalerite-tetrahedrite- bismuth telluride & alteration consisting of quartz-epidote-actinolite-garnet-pyroxene-chlorite considered to be retrograde overprinting of prograde skarn assemblages.
Pyrite-magnetite-chalcopyrite-molybdenite & alteration consisting of quartz-sericite-gypsum-carbonate stockwork, disseminated and microveinlet zones.
Pyrite-chalcopyrite-sphalerite-bornite-galena-magnetite-tetrahedrite-
bismuth tellurides occurring as quartz veins, and quartz breccia localized in NNE to NE trending shear zones enveloped by K feldspar-sericite-magnetite-
hematite-epidote-garnet-actinolite-pyroxene-chlorite alteration and coeval with syenitic phases of the Lehto Batholith.
Massive pyrite-chlorite lenses 1-3m wide contain weak chalcopyrite mineralization.
