A 150-metre wide band of medium grained, pale bluish grey and white striped limestone outcrops on a point 1.2 kilometres east of the southern tip of King Island in a roof pendant within granitic rocks of the Tertiary-Jurassic Coast Plutonic Complex. The limestone strikes 165 degrees for at least 550 metres and dips vertically. On the margins of the band the limestone becomes interbedded with schist and argillite. Numerous dykes intrude the limestone. Two chip samples taken in succession across a total width of 30 metres in the centre of the band averaged 52.64 per cent CaO, 1.22 per cent MgO, 1.81 per cent SiO2, 0.30 per cent Al2O3, 0.21 per cent Fe2O3 and 0.01 per cent sulphur (Canada Bureau of Mines Report 811, page 176, Samples 31, 31A).

Some development work was carried out by F.J. Beale in 1931. The deposit was eventually quarried in 1949 for 3 months by F.J. Beale, supplying limestone for the pulp mill at Ocean Falls.
