Located 7 kilometres north-west of Mukinbudin, on the north side of the Mukinbudin-Bencubbin Road. Also known as Snowstone Quarry. The large white mullock hill at the mine can be seen for miles across the flat wheat fields. Mining started here for Quartz around 1970, and in the 1990's was the second largest producer of feldspar in Western Australia. The deposit is divided into the western, central, and eastern pits, and the mullock hill.

The pegmatite contains a quartz core, microcline intermediate zone, discontinous plagioclase (albite)-quartz replacement unit, quartz-microcline-biotite wall zone, and sometimes a medium grained microcline-plagioclase-quartz-biotite border zone.

Exploratory drilling started sometime before 1970. By 1979, Snowstone Pty Ltd had mined 35 882 tonnes of quartz. Matlock Mining purchased the mine in 1980, and in turn Commercial Minerals Ltd purchased the mine in 1988. Commercial Minerals switched to mining feldspar until 1997 when mining ceased.

'Libraries' of rare giant black biotite books can be seen in all three quarries. Of interest is black allanite-(Ce) at the entrance to the western quarry. In 2001, zircon variety cyrtolite, were discovered, 2-8 cm in diameter. They are found rooted to base of biotite crystals, in association with magnetite crystals and fergusonite-(Y). Smoky quartz crystals to 30 cm long were once found in the eastern quarry. Lustrous clear to smoky quartz (some with hematite inclusions, overgrowth phantoms, and multiple parallel growths) up to 25 x 15 cm have been reported as found on the mullock hill, although my investigations would indicate nothing remains on the surface.
