Feb 28, 2020 (Sheree Hinz) - The mineralized zone consists of brecciated argillite cemented by quartz-carbonate stringers and sulphides. The mineralized zone is associated with a narrow gabbro dike striking 50 degrees east. Sulphide mineralization consists of pyrite, chalcopyrite, and arsenopyrite. The sulphides are erratically distributed throughout the breccia, although some massive sections do occur. Gold is present as very fine grains; some is free or associated with chalcopyrite, but the greater proportion is in arsenopyrite.
