Location Method: Data Compilation
1918-25 : Tory Hill Marble and Mica Co Ltd shipped 3,396.5 pounds of thumb-trimmed amber mica from these lots. The old workings could not be located in 1943 but local residents said that the shipments were from several deposit and a pit is described on this lot. Whether mica or molybdenite was produced from it is questionable - this pit was shallow and 15 x 25 ft., situated between a disused farmhouse and a barn, 12 chains north of Little Bear (Glamor) Lake (1943).

Jan 25, 2017 (A Wilson) - This locality is known for its large crystals. Black amphibole occurs as large crystals and crystal groups in buff to pink coarsely crystalline calcite. Large crystals of biotite about 30 cm in diameter, and light green apatite crystals measuring up to 30 cm long occur with the amphibole. Titanite crystals measuring up to 20 cm long occur in calcite and in the granitic rocks. The calcite fluoresces bright pink in "short" ultraviolet light.
