Geological setting: The country rock is comprised of mafic/intermediate volcanics and is weakly foliated with distinct (<1m wide) shear zones. Quartz veining occurs oblique to the regional structure and veins have a strike of ~80 degrees and a steep dip. The veins located at the property are believed to be a result of the lateral movement of one rock surface against another, also known as shearing, indicating the presence of an Archean lode-gold type deposit.

Mineralization: Mineralization is characterized as: 1) disseminated to clotty vein hosted sulfides and 2) sulfides present as disseminated euhedral crystals found in wall rock. Mineralization is in the form of pyrite, pyrrhotite, chalcopyrite, bornite, and malachite.

Importance: In general lode deposits include a wide range of lithological and structural types. The veins at Alkenore usually consist of coarse or “cherty” quartz. Higher grade gold occurs in small fractures within the larger veins and is associated with iron sulfides.  Mineralization is usually in the form of either 1) Au-bearing silica-sulfide replacement, and 2) Au-bearing quartz veining that is characteristic of many other Archean greenstone gold deposits in NW Ontario. Heritage will look to conduct further work at the prospect to help define the presence of a much larger deposit along strike and depth.
