Feb 06, 2018 (Therese Pettigrew) - Several large veins occur on mining location R 64. They vary in width from 3 to 8 feet. In the veins various forms of quartz preponderate and are accompanied in places by varying proportions of green fluorite, calcite, and occasionally a little barite. At one exposure, a vein consists almost entirely of solid vitreous quartz, and has a marked, banded or "combed" appearance due to different-coloured layers (amethyst, white, translucent, etc). The fluorite seems to have been mostly deposited between the irregular surfaces of these layers. The metallic minerals sphalerite, galena, and pyrite occur occasionally, in disseminated grains, and in the case of pyrite also as very thin films coating cleavage planes, jointing, etc. The enclosing rocks are of Animikie iron formation (Tanton, 1931). It was reported that there are traces of silver in the veins on the property.
