Exploration activity on Exploration Licences 5016 (Whichelby), 5308 (Mount Hall), 5398 (Sceales), 5787 (Yanerbie) and 5814 (Tootla) is focused on gypsum and kaolin deposits. The tenements are grouped in the Poochera Project Amalgamated Expenditure Arrangement (AEA). The licences are in the Streaky Bay area of the Eyre Peninsula, Tootla is 40 km east of Streaky Bay and contains the Carey’s Well deposit and is being explored for kaolin, as is Whichelby located 16 km east of Streaky Bay. Sceales, 14 km south of Streak Bay, and Yanerbie, 6 km south of Streaky Bay, are being explored for gypsum. On Mount Hall, located 17 km northwest of Port Kenny, exploration is focused on kaolin associated with the deep weathering of the Proterozoic basement. Long stability in the region has allowed for the preservation of thick mantle of deeply weathered material, while the Tertiary sedimentation within palaeochannel was associated with periods of intense weathering and kaolinization of the Proterozoic basement. While arid Pleistocene conditions led to widespread calcrete deposits development and extensive gyspiferous dune formation across the tenements. On EL 5814 external research projects were undertaken. These included a review of newly to hand, excellent results obtained by recently commissioned research into using kaolin of high halloysite content to create high strength, lightweight proppants. Further to this, a university student's sponsored literature review for establishing knowledge of the current and envisaged industrial applications of kaolin and halloysite was undertaken and a university student's sponsored proposal for conducting research into the optimal utilisation of kaolin and halloysite as concrete fillers was underway. [See included reports] Information supporting an ASX release made by Minotaur on 23/2/2016 of a maiden, JORC 2012 - compliant Inferred Mineral Resource for the company's Lake Purdilla gypsum deposits located on EL 5398 : 86.8 Mt @ 91% purity, for combined lakebed infill selenite (density 1.3 g/cc) and dune gypsarenite (density 1.2 g/cc). No significant technical work was completed on either EL 5016 Whichelby or EL 5308 Mount Hall, activities undertaken included a review of native title and cultural heritage, historical drill data, and investigations into potential groundwater targets. Results were received for drilling completed on EL 5787 Yanerbie in the previous reporting period [ENV12564 CNO:20041838]. During the second year of the project, exploration efforts were focused on EL 5814 and EL 5389. Significant research was undertaken with university groups on EL 5814; at the University of Adelaide the high halloysite kaolin was evaluated for usage as a ceramic proppant, as well as evaluating the high halloysite kaolin as a strengthening filler. The University of South Australia commenced a study into halloysite nanotube characterisation parameters and adsorption properties. The maiden JORC compliant resource for Lake Purdilla Gypsum Deposit on EL 5398 was communicated to potential investors, however development of the project remains constrained by the lack of local bulk shipping facilities. A reconnaissance site visit was made to the Larson and Purdilla Lakes on EL 5398 to monitor rehabilitation process from the 2015 drilling program. The strategic promotion of kaolin and gypsum continued, along with discussion with marine and transport logistic companies in relation to the need for the western Eyre Peninsula to have access to a modern and efficient bulk commodity port. During the third year of the project extensive testwork and research with different institutions continued, along with the commencement of the Andromeda Metal Ltd joint venture (25th June 2018). The evaluation of high halloysite kaolin as a cement/mortar additive, with bench scale testwork developed and ready for processing trials. A civil engineering honours project at Flinders University investigating the use of low and high halloysite kaolin in geopolymer mortars was started in 2018. Work on halloysite nanotube characterisation studies at the both the University of South Australia and the University of Newcastle continued. Quantification of halloysite content within Carey’s Well resource continued with Ongoing testwork by CSIRO with additional confirmatory testwork by University of Newcastle research. High purity alumina (HPA) testwork trials commenced with BHM Process Consultants. The Carey’s Well resource estimate was update to JORC 2012 standard, with the EL 5814 containing a Total Resource (measured + indicated + inferred) of 23.9 Mt of kaolinised granite.
