Mineralization Comments

Mar 23, 2018 (Therese Pettigrew) - In what is now the playgrounds of Ecole Secondaire Catholique de la Verendrye in the city of Port Arthur, at the corner of Prospect and Dawson streets, a pit 30 feet deep was sunk prior to 1887. This was known as the Singleton mine. A vein of quartz here occupies a fault striking north 75 degrees east. The rock on the north side of the fault is shale, and on the south taconite underlain by shale. The latter rocks are well exposed in a cliff 10 feet high about 100 feet west of the pit. Another vein, less than one foot wide, consists of quartz and strikes north. Rich bunches of native silver are said to have been obtained in the workings (Tanton, 1931).
