Update on Lithium Research and Development Joint Venture

Further to the announcement on 21 June 2017 regarding the expansion of the lithium ore leaching joint venture between Alexander and Dr. Nicholas Welham, the Company is pleased to provide an update on recent activity.

High quality samples and/or concentrates of the lithium bearing minerals zinnwaldite, lepidolite, petalite and spodumene have now been received from prospective projects, advanced projects and active operations in North America, Europe and Australia.

Once the mineralogical characterisation has been completed, the ores will be subjected to a range of different chemical treatments to assess their viability for leaching lithium under ambient conditions. The reagents selected will include those known to dissolve lithium minerals to provide a baseline against which the new reagent scheme(s) can be compared. Once the range of options is narrowed down a smaller suite of reagents will be trialled under varying conditions to assess optimum leaching conditions. The optimal conditions for the most prospective reagent(s) will then be used to generate a large volume of solution which will be converted into lithium carbonate using conventional technology.

It is anticipated that the initial stage of work will be completed within three months.
