Lithology Comments

Jul 27, 2022 (Therese Pettigrew) - The property is underlain by massive, medium-grained biotite granite, exhibiting pale grey and pink varieties that merge into one another. At test pits the rock consists chiefly of pale grey granite that is traversed by a system of joints dipping at very low angles toward the north (Tanton, 1938). The rock is exposed in a southwest-trending ridge with two small quarry openings in it. The rock is fine- to medium-grained, massive, light grey biotite granite. Vertical joints oriented 060 degrees and 180-200 degrees are spaced 2 to 6 m apart. Sheeting varies from 1 m at the east pit to 3 m at the west pit. The colour is light grey becoming pale pink to the north. The granite exposed in the workings is all light grey. There are no obvious knots or inclusions (Storey, 1986).
