Ann: Chairman's AGM Address, page-5

In context of what you quoted and also what @Stocrates touched on...

"Our potential acquisition of IMERYS Australia’s assets will also give us access to high grade and valuable pharmaceutical grade kaolin. This is a very high value product ranging from A$3,000 to A$10,000 per tonne, we will be examining avenues to increase production and supply of all these products in the near future. We have also been investigating potential higher value emerging markets within the tech space including, battery and super capacitor 4N and 5N raw materials, CO2 capture and storage and construction materials including concrete."

Looks like there are some pretty exciting markets for our kaolin with a BOD that is thinking outside the box!
