Jan 25, 2017 (C Papertzian) - Paragneiss and marble is intruded by gabbro, syenite, granite and granite pegmatite. Radioactivity occurs in leucogranite pegmatite and syenite pegmatite bodies 2-50 ft wide. Allanite is present.
Feb 11, 2017 (A Wilson) - In the north part of lot 34 concession 2 a weakly radioactive pink, coarse leucogranite pegmatite with pathches of graphic granite has been explored by 4 packsack drill-holes. The pegmatite body is about 100 by 300 feet in dimensions and gave geiger counter readings of 3x-6x, with rare spot highs to a maximum of 10x. No radioactive minerals were seen. A scintillometer survey of the property was completed in July, 1955. This indicated six radioactive anomalies. In 1955 and 1956 granite pegmatite bodies were explored by one drill-hole 731 feet in length , and by six packsack drill-holes totalling 288 feet.
