Spey Resources Extracts 99.5% Lithium Carbonate Using Ekosolve™ Process From Our Flagship Candela II, Incahuasi Salar Project


Vancouver, British Columbia, Oct. 28, 2022 (GLOBE NEWSWIRE) -- Spey Resources Corp. (CSE: SPEY) (OTC: SPEYF) (FRA: 2JS) ("Spey” or the "Company") is pleased to announce that the Chemical Engineering Department at the University of Melbourne, Australia has successfully produced lithium carbonate from lithium chloride extracted from the Company’s brines in Incahuasi Salar at the Candela II Project using the Ekosolve™ process.

Spey has acquired the first Ekosolve production licence, which prioritizes the Company to be the first client to commission Ekosolve to complete the construction proposal, preliminary and plant engineering and manufacturing of the plant at Incahuasi. EkoSolve has issued seven other licences to date and will progressively commence engineering after Spey engineering is completed.

The brines and the lithium carbonate that was produced are being assayed by an external laboratory to corroborate the results achieved by the University of Melbourne and the Ekosolve team. The brine was subjected to 10 phases of continuous processing that took approximately 22 seconds for the solvent to extract the lithium in each phase.

The 10th phase had extracted 135.05gm of contained lithium from 140.23gm, a 96.03% recovery rate. The purity of the lithium carbonate was set at 99.5% based on the sodium carbonate used to convert the chloride. The Mg:Li ratio was more than 15:1, and the EkoSolve™ process performed exceptionally well. The trial was undertaken by Ekosolve Ltd. and reported to Spey.

Phil Thomas, CEO of the Company, said “we are delighted to achieve these results. This not only proves the validity of the Ekosolve™ process for Incahuasi brines, but also the fast processing time using columns. Ekosolve Ltd. is planning to build a 100 tonne mini plant in Salta and the Company is in active discussions with Ekosolve Ltd. regarding a potential joint venture opportunity.”
