Ann: Third Quarter Activities Report-HSK.AX, page-14

Taken from report 24/11/2017

The Moberly silica operation has mined and processed high purity silica sand for a diverse number of industrial applications since 1983. Our SILWITE® products have a purity ranging from 99.15% to 99.55% SiO2, well exceeding the requirements for silica sand raw material in flint grade glass, ceramic and foundry grades.

Our products have extremely low iron oxide content and therefore in these applications will not interfere with the colour of the ultimate end product. The Project is scheduled to produce high-quality American Petroleum Institute (API) standard specification proppant (Mount Moberly White™). Construction completion, commissioning and first production is expected in Q3 2017.

The Project’s Competent Person estimated Measured and Indicated resources of 37.5 million tonnes of silica with 70% recovery to 30# to 140# frac sand products1 , the Stage One Moberly Project has a nameplate production output capacity of 300,000 tonnes per annum.

So worst case they earn $9 mill USD ( About $12 mill AUD ) PA $30 a ton.. decent case $90 a ton = $36 mill a year , add a p.e. ration of 5 & SP should be around 40c
