Limestone of the Lower Cambrian Reeves member of the Laib Formation was once quarried at the Reno mine (082FSW036), 11 kilometres east of Salmo. The unit is exposed as a narrow band striking north for 950 metres and dipping approximately 50 degrees east on the west flank of the Sheep Creek anticline. The limestone was burned to produce lime for milling purposes at the mine. A total of 738 tonnes of limestone were quarried between 1930 and 1934.
