Aug 14, 2024 (Therese Pettigrew) - The rocks in the vicinity consist of granite gneiss containing bands of dark-coloured paragneiss. One band of paragneiss constituting the northwest wall of the pit resembles altered greywacke. The beds strike approximately N. 200 E. and dip about 45* S. E. The pegmatite exposed in the pit consists of pink potash feldspar and quartz" (Hewitt, 1951).

Aug 14, 2024 (Therese Pettigrew) - "A feldspar pit 55 feet long, 25 feet wide, and 15 feet deep is situated in a pegmatite dike that forms part of the northwest shore of Bobs Lake on the northeastern part of Lot 28, Concession 5 of Bedford Township. The pit lies within a chain of the lake shore. Feldspar was produced at this location during the early part of the present century by the Suroff Feldspar Mining and Milling Company and by their successors, Dominion Feldspars, Limited. The feldspar was transported by boat to Fish Creek at the southwest end of Bobs Lake. From that point it was drawn by teams a distance of about 2 miles to a grinding mill, which was situated near Duncan lake at Fish Creek crossing on the Kingston and Pembroke railway" (Hewitt, 1951). Hewitt (1952) reports that 145 tons of material were shipped from this prospect during 1919, the only year of operation.
