Several bodies of limestone occur as inclusions along the coast in granitic and dioritic rocks of the Jurassic to Tertiary Coast Plutonic Complex, 13 kilometres northwest of Powell River.

A limestone mass exposed, on the shore cliffs on the northwest corner of Lot 5347, is 15 metres wide and 46 metres long. A second mass, 90 metres to the northwest, is 90 metres long and 60 metres wide. A third body, 400 metres to the northwest, is at least 300 metres long. A 20.7 metre long chip sample taken across the north- west end of the first deposit contained 51.64 per cent CaO, 2.38 MgO, 2.22 per cent insolubles, 0.22 per cent Al2O3, 0.25 per cent Fe2O3, 0.03 per cent sulphur and 43.08 per cent ignition loss. A second 30 metre long sample taken across the middle of the second deposit contained 51.69 per cent CaO, 3.32 per cent MgO, 1.20 per cent insolubles, 0.15 per cent Al2O3, 0.14 per cent Fe2O3, 0.03 per sulphur and 43.26 per cent ignition loss (Bulletin 40, page 94).
