The dominant minerals are pyrite, tetrahedrite, sulfosalt
, sphalerite with lesser galena and chalcopyrite.
Visual coarse sulfosalt
mineralization, possibly tetrahedrite, to 1 millimetre in size was noted in the basal part of the fault zone between 170 and 171 metres in the core.
being) comprised (sic) of galena, sphalerite and a diverse suite of Ag and sulfosalt
minerals in a gangue of siderite, quartz, or calcite.
Shear Vein mineralization is made up of blue-gray quartz vein material containing pyrite, sulfosalt
minerals and arsenopyrite, and sheared and crushed fault breccia and gouge.
Geochemistry of drill cores indicates silver in association with silver sulfides or sulfosalts
Native silver and (to a lesser extent) native bismuth generally occur with cobalt-arsenides, sulfarsenides and sulfosalts
in near-vertical carbonate ([+ or -] silicate) veins cutting Huronian sedimentary rocks of the Gowganda Formation, Archean greenstones, and the Paleoproterozoic Nipissing diabase (Fig.

Native gold, present in trace amounts, is associated with chalcopyrite, galena (PbS), sphalerite (ZnS) and copper-lead-bismuth sulfosalts

The dominant minerals are pyrite, tetrahedrite, sulfosalts
, sphalerite, galena and chalcopyrite.
Silver values up to 90 g/t coincide with the gold and possibly indicate the presence of silver sulfosalts
in the host saprolite.
This year's first drill hole targeted the northern trend of the "A Vein" on the Bulldog Vein system and intersected a 15-foot vein that contains galena, sphalerite, chalcopyrite, and fine-grained silver sulfosalts
