A 120-metre thick Lower Permian sequence of grey, recrystallized limestone with interbedded greywacke, chert and argillite of the Devonian to Permian Chilliwack Group, is exposed for 700 metres along the northwest flank of a northeast trending knoll on the south side of the Chilliwack River, 18 kilometres east of Vedder Crossing. The section consists of an upper 60-metre thick limestone member separated from a lower 30-metre thick limestone member by 30 metres of cherty argillite and greywacke. The sequence strikes northeast and dips variably southeast. Both members contain chert bands and lenses. A chip sample across the top 30 metres of the upper limestone member analysed 43.6 per cent CaO, 2.50 per cent MgO, 15.1 per cent insolubles, 0.47 per cent R2O3, 0.42 per cent Fe2O3, 0.05 per cent MnO, 0.03 per cent P2O5, 0.06 per cent sulphur and 37.8 per cent ignition loss (Bulletin 40, page 41).

In 1998, three diamond drill holes were completed for a total of 367.9 metres (Assessment Report 25596).
