Locked cycle testing is an important process in ensuring an accurate process flow sheet and verified inputs to the upcoming Definitive Feasibility Study (\"DFS\").\n \n \n \n \n \n \n \n \n Highlights:\n \n \n \n ·\n Three LCTs were completed to simulate the continuous operation of a process plant and to refine the reagent consumption of the process flowsheet\n \n \n ·\n The LCT yielded a concentrate grade of 5.5% Li2O ('SC5.5') and global\n recoveries in the range of 77%-81% at laboratory scale\n \n \n ·\n This supports the results previously reported in the ore\n variability programme, which achieved Li2O recoveries in the range of 70%-79.5% at laboratory scale with low levels of impurities, and suggests that improved levels of recoveries are achievable\n \n \n ·\n Optimisation of the reagent dose rates between test 1 and test 3 showed a 39% reduction in reagent use which should have significant operating cost ('OPEX') benefits for the Project which will be captured in future economic evaluations\n \n \n ·\n These positive results will be utilised in resource and mine optimisation, and as the basis for the upcoming DFS to support the proposed development\n \n \n ·\n Based on the encouraging results achieved to date, planning for the pilot plant test work programme is underway\n \n \n \n \n \n To view the full press release including any maps, figures or tables, please use the following link:\n \n \n \n http://www.rns-pdf.londonstockexchange.com/rns/5556P_1-2022-6-20.pdf\n \n \n \n \n \n \n \n \n \n David Archer, Savannah's Chief Executive Officer s...
