Recharge Resources Upgrading Lithium Brines From Pocitos Lithium Project To Battery Grade Lithium Carbonate

About this update from Uranium One Mining Corp.

[{"type":"text","content":" Vancouver, BC, March 14, 2023 (GLOBE NEWSWIRE) -- Recharge Resources Ltd. (\"Recharge\" or the \"Company\")(RR: CSE) (RECHF: OTC) (SL5: Frankfurt) announced today that its brine samples containing 161 ppm lithium taken from the Company’s 2022 DDH3 drill program at the Pocitos lithium brine project in Salta, Argentina, are being converted from lithium chloride to battery grade lithium carbonate. Recharge is using Ekosolve™️ 10 stage extraction process, to produce lithium chloride, as contemplated as one of the end products under the offtake LOI between Recharge and Richlink Capital’s clients. Now a further pre-engineering step is being completed to produce lithium carbonate from the Pocitos lithium brines. This additional work will also act as an Ekosolve™ Extraction performance test recovery, in consideration for a full sized plant scale-up of 10,000-20,000 tonnes per year Ekosolve™ Lithium Brine Extraction plant implementation at the Pocitos project, under the Company’s technology licensing agreement announced on September 27th, 2022. Figure 1. Recharge’s QP Phil Thomas at Ekosolve™️ Testing Facility – Melbourne, Australia The Ekosolve™️ Lithium Solvent Exchange Extraction process can efficiently manage the processing of lithium brines to produce lithium carbonate with a grade higher than 99.2% and a recovery of 97%, far exceeding any ion exchange or adsorption process commercially available to date. Ekosolve™️ is licensed from the University of Melbourne, Australia and Ekosolve Ltd is the exclusive master licensee. The key advantage of the Ekosolve system is the exceptionally high lithium yield with past yields of 93%-96% and 97.5% of the solvent being reclaimed. Other systems such as adsorption may achieve 72-80% yield, fractional crystallization of 50-70%, and membranes and ion exchange up to 70-90%. In adsorption and ion exchange systems, extra processes may be required to manage the magnesium and boron content in the brines whereas this is not an issue with the Ekosolve process. Hence the capital expenditure and operating costs are anticipated to be substantially reduced. A significant additional benefit is that evaporation ponds are not required, providing a more eco-friendly solution. The initial study cost for Recharge was USD $28,000.
