The Highway 16 showing is located 72 kilometres east of Prince George along highway 16 in an area underlain by platformal sediment- ary rocks of the Cariboo Terrane. The dominant rocks of the region are limestone, dolostone, shale, siltstone and phyllite of the Mural Formation of the Lower Cambrian Gog Group.

A 400 metre long roadcut exposes dense, black, well-bedded limestone of uniform appearance. The beds, which strike at 110 degrees and dip 25 degrees north, vary from a few centimetres to a few metres thick.

A sample of chips taken over a stratigraphic thickness of 6 metres contained 53.01 per cent Ca0, 0.84 per cent MgO, 1.78 per cent insolubles, 0.70 per cent R203, 0.53 per cent Fe2O3, trace MnO, 0.03 per cent P2O5, 0.13 per cent sulphur and 42.74 per cent ignition loss (Geology, Exploration and Mining 1969 p.390).
