Mineralization Comments

Mar 23, 2018 (Therese Pettigrew) - At the northwest corner of Hebert and Peter streets, R. Thomson discovered native silver in a vein one inch wide exposed in an excavation made for the foundation of a house. Animikie iron formation composed of thin layers of chert and iron carbonate are exposed in this vicinity. The rocks dip 20 degrees toward the ESE. Veinlets less than 3 inches wide may be seen in nearly all the outcrops. In the vicinity of the discovery, there are several ½ inch veinlets spaced at intervals of 4 feet and trending from 20 degrees to 30 degrees east of north. The material consists of white quartz, amethyst, pink barite, white calcite, small amounts of sphalerite and chalcopyrite (Tanton, 1931).
