The Olalla Creek Limestone quarry is located along the north branch of Olalla Creek, 5 kilometres northwest of Olalla, British Columbia.

The regional geology of the area consists of a series of Carboniferous to Triassic volcanic and sedimentary rocks that have been intruded by Jurassic granitic Okanagan intrusions. Larger intrusions are composed of granite and granodiorite, while smaller stocks are composed of diorite and gabbro. Numerous sills, dikes and apophyses are associated. Carboniferous to Triassic rocks are assigned to the Shoemaker and Old Tom formations. These rocks form the eastern limb of a large anticlinal fold with fold axes striking roughly north.

A northwest trending lens of limestone (marble) up to 60 metres wide outcrops for 150 metres along the north side of Olalla Creek, 5.1 kilometres northwest of Olalla. The limestone lies in tuff, greenstone and chert of the Shoemaker Formation.

The lens is comprised of medium to coarse grained, white to grey crinoidal limestone (marble), with irregular patches of reddish and brown limestone. The rock is brecciated and well fractured. The closeness of fracturing and irregularity in colouring severely limited its values as a building stone. A thin section of the brown crinoidal limestone contained 20 per cent disseminated quartz grains. A sample of chips taken at 1.5 metre intervals for 46 metres contained 53.14 per cent CaO, 0.16 per cent MgO, 3.65 per cent insolubles, 0.60 per cent R2O3, 0.41 per cent Fe2O3, 0.13 per cent MnO, 0.05 per cent P2O5, 0.008 per cent sulphur and 41.93 per cent ignition loss (Minister of Mines Annual Report 1968, page 323).

In 1968, the deposit was assessed by Apex Exploration & Mining Co. as a source of dimension stone and 604 tonnes of limestone were quarried for Ramshead Quarries Ltd. In 1984, Cominco Ltd. explored the area for precious and base metal mineralization.
