Two parallel shear zones each about 46 centimetres in width, trend northeasterly and dip northwesterly. The zones occur in porphyritic andesite which Geological Survey of Canada maps indicate belongs to the Jurassic age Hazelton Group. Quartz veining in the shear zones hosts pyrite, marcasite, chalcopyrite, arsenopyrite, galena, sphalerite and hematite mineralization. Good gold and silver values are reported.
