May 26, 2023 (Therese Pettigrew) - A small open cut, 25 x 30 feet, at the east end of a rock ridge about 100 feet high exposes coarse pink granite pegmatite in contact with pink biotite granite, grey hybrid granite gneiss, and amphibolite. The granite pegmatite contact with the amphibolite is sharp and well-defined striking N60E, and dipping 50NW. The exposed width of granite pegmatite is about 20 feet, the contacts with granite and granite gneiss being gradational. Masses of pink biotite granite are present within the granite pegmatite (Satterly, 1971).

May 26, 2023 (Therese Pettigrew) - The granite pegmatite consists of pink potash feldspar in masses to 2 feet across, grey quartz to 2 feet, white soda feldspar to 4 inches, an occasional book of biotite to 1 foot, and a few rough crystals or masses of radioactive mineral reported by Peter Malcovitch to have been identified as euxenite-polyerase. One mass 10 inches across is largely titanite with some euxenite. This mass gave a reading of 2000 on the EA-135 PI (Internal), the rest of the granite pegmatite reading 500 counts per minute. The rock exposed above the open cut is hybrid granite gneiss. Other exposures of granite pegmatite are reported to occur to the west (Satterly, 1971).
