Jan 29, 2021 (Sheree Hinz) - The quarry exposes 18.85 m of Amabel Formation consisting of upper 3.1 m of coarse to very coarse crystalline, medium-bedded, reefal dolostone and the lower 16 m of fine to medium-crystalline, reefal dolostone, massive without stylolitic partings. Bioherms of up to 60 m in length and 10 m in height dipping in flank up to 20 degrees are present. The Reynales formation which underlies the Amabel formation consists of interbedded argillaceous dolostone and shale. Crinoid and coral fossils occur in some of the beds and reef mounds up to 30-90 m wide and 6-15 m high are exposed in the upper part of the quarry.

Jan 29, 2021 (Sheree Hinz) - Grey to buff porous dolomitic limestone of the Amabel and Reynales formations of Silurian age occurs at this quarry. "Micro" crystals of calcite and dolomite line vugs in the limestone. Gypsum occurs as colourless transparent tabular masses (selenite) and as white fibrous masses. Pyrite is associated with gypsum. Analyses by the Provincial Assay Office in 1959 reported 30.3% CaO, 21.15% MgO in sample 1, 29.3% CaO, 21.13% MgO in sample 2, and 30% CaO, 21.11% MgO in sample 3 (IMR027 p.20).
