Two or more bodies of bluish grey limestone form a 300 metre long, 60 metre wide northeast trending belt in granitic rocks of the Tertiary-Cretaceous Coastal Plutonic Complex on Lot 4, 1.6 kilometres north of Bold Point on the east side of Quadra Island. A composite of six chip samples taken from various parts of the limestone belt analyzed as follows: 53.35 per cent CaO, 0.72 per cent MgO, 4.60 per cent insolubles, 0.59 per cent R2O3, 0.10 per cent Fe2O3, 0.01 per cent MnO, 0.03 per cent P2O5, 0.02 oper cent sulphur and 40.23 per cent ignition loss (Bulletin 40, pages 93, 94)

A few tonnes of limestone are reported to have been quarried from here before 1925.
