Ann: Quarterly Activities Report - June 2018, page-4

‘The Company’s in-house Stage 1 processing test-works have currently resulted in removal of more difficult impurities like sulphates, boron, calcium and magnesium to acceptable levels, and the current focus is ensuring targets for process recovery and re-agent use are met. In addition, current test-works are targeting to replicate results from varying batches of LCE product to ensure product quality consistency, which is critical for future product sales to battery and cathode manufacturers.
These processing works are highly complex and are a key driver for the Company, which, when successful will allow the Company to deliver on our ultimate project strategy - to build a sustainable lithium production company.
The Company’s Rincon Lithium Project personnel, headed by the Company’s MD – Mr Jerko Zuvela and its JV partner – Mr Pablo Alurralde, remain confident the Stage 1 plant works are progressing well and will achieve its milestone objectives. They are also hastened to complete the test-works as quickly as possible to continue our fast-track development of the Rincon Lithium Project.’

Read between the lines.. that is BG. Now they are focusing on recovery levels of the Li itself and adjustments for different input batches
