Feb 06, 2018 (Therese Pettigrew) - A vein occurs on the south half of lot 9, concession I, O'Connor township, on a property owned by Mr. Robert Hymers of Hymers. It has been exposed in workings on the east side of a diabase-capped hill, 50 feet north of the road that runs westerly between Gillies and O'Connor townships. An open-cut has been driven south 80 degrees west into the hillside along the vein for a distance of 25 feet, and on the face of this hillside along the vein for a distance of 25 feet, and on the face of this working the vein is exposed through a vertical distance of 15 feet. The vein occupies a fault in flat-lying, wavy-bedded greenalite-taconite of Animikie age. It strikes north 80 degrees east; the southern wall is vertical, the northern dips approximately 75 degrees south. The vein is 21-feet wide in the upper part of the workings and 6 inches wide in its lowest exposure. Two-thirds of the volume of vein material consists of coarsely crystalline, interfering platy, white barite. The other non-metallic minerals, in order of abundance, are: coarsely crystalline white calcite, green fluorite, and white quartz. Small showings of galena and sphalerite occur locally in the vein.
