Poochera is a kaolin district of global significance. It contains many kaolin deposits with unique characteristics, including the deposit of "bright white" kaolin at Carey's Well, some 45km east of Streaky Bay on western Eyre Peninsula in South Australia
Proppant formulation test work conducted in the first quarter of 2015 using Poochera kaolin returned very encouraging results, with several formulations of high-halloysite material matching the benchmark properties of commercial HSLW (high-strength light-weight) proppants (Figure 1). Additional samples of high-halloysite kaolin were prepared for further proppant testwork, as well as for trials and characterisation testwork by other potential offtake partners in the strengthening filler and ceramic markets.
