The Quartzite Point occurrence is located close to the east shore of Shuswap Lake, about 9.4 kilometres northwest of Sicamous.

Quartzite occurs as a band, 7.6 to 9.1 metres thick, between layers of gneiss within the Hadrynian? to Paleozoic Eagle Bay assemblage. It is exposed for 275 metres and trends northeasterly with a gentle dip to the southeast. The quartzite is medium grained and white to glassy, with patches of brown stain on fracture surfaces.

In 1928, one sample reported as a representative sample from a trench, assayed 98.20 per cent SiO2, 0.12 per cent Fe2O3, 0.77 per cent Al2O3, 0.57 per cent CaO, 0.34 per cent MgO and 0.17 per cent LOI. In 1958, another chip sample taken across the width of the quarry exposure assayed 97.48 per cent SiO2, 0.59 per cent Al2O3 and 0.02 per cent Fe (Open File 1987-15, pages 23,24).

Development work consisted of a quarry 12 by 4.5 metres, pits, stripping, two adits (7.6 metres and 18.2 metres) and a crushing plant. A shipment of 90 tonnes was made in 1923 and an unknown amount around 1962-1965.
