Summary:
The material that is mined at Moberly is the Ordovician Mount Wilson Quartzite unit. Near Golden it reaches a maximum thickness of 480 metres at Horse Creek (less in the mine area) and Mount Moberly is the northern limit of the unit, where it is terminated by a thrust fault. The quartzite is typically grey to buff coloured massive orthoquartzite with some evidence of crudely laminated and cross laminated beds near the base.
Bedding generally strikes around 118° magnetic and is vertical to steeply NE dipping. The rock consists of an orthoquartzite which is variably de-cemented (ie by removal of the silica ‘cement’ binding the grains) so that most of the mining area consists of ‘altered’ friable or ‘sandy’ quartzite to various degrees. There appears to be no systematic variation or control of the de-cementing. The composition of the rock is +99% SiO2 as quartz, with the remainder being silicate clays and very rare other silicate minerals.
Petrological studies show that the sand grains within the rock vary between 0.841mm to 0.105mm in diameter (20 mesh (#) to 100 mesh (#) on the US scale).
The only potentially economic mineralization observed within the map area is quartzite. The quartzite found on the property is a sedimentary deposit known as the "Wonah Quartzite", probably of Ordovician age and is found as two distinct members. The first is a friable quartz sandstone which comes in contact with limestone to the southwest in the area of the s ........
Summary:
The Moberly silica sand deposit was drilled by four cored holes in 1982 with logging was largely done on a qualitative basis and indicates the homogeneity of the deposit at depth, although this would be essentially down-dip of the sandstone beds. Extensive exposure and mining in three dimensions by open cut mining.

Summary:
Frac sand is manufactured from naturally occurring pure quartz sand via a straightforward crushing, grinding and washing process and is used as a proppant for the oil and gas sectors; chiefly the shale gas industry.
