Vancouver, British Columbia, Oct. 31, 2022 (GLOBE NEWSWIRE) — Spey Resources Corp. (CSE: SPEY) (OTC: SPEYF) (FRA: 2JS) (“Spey” or the “Company“) is pleased to provide further information regarding its recent extraction of 99.5% battery grade lithium carbonate using the Ekosolve™ process. As announced in the Company’s news release dated October 28, 2022, 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 the University of Melbourne (UoM) chemical engineering department and reported to Spey.

All sampling received from Spey’s Incahuasi project was sampled by SGS, Leeder Laboratories in Melbourne, and the UoM Chemical engineering department to validate the lithium content. The exploration program sampling was subject to a company standard of internal quality control and quality assurance programs which include the insertion of certified reference materials, blank materials and brine duplicate analysis. The total amount of brines analysed was approximately 600 litres. All samples were processed for lithium analysis by ICP-5AM48. UoM, Leeder and SGS Argentina quality systems all conform to requirements of ISO/IEC Standard 17025 guidelines and meet assay requirements outlined for NI 43-101. Data verification of the analytical results included a statistical analysis of the standards and blanks that passed certain parameters for acceptance to ensure accurate and verifiable results.

The lithium carbonate produced after the B1 sample of 200 litres was processed using the EkoSolve™ process was analysed using ICP-OES. The lithium concentration in the original brine and batches 1 to 11 following the 10-stage extraction process were analyzed via ICP-OES. Prior to analysis, the samples were spiked with 5, 10, 20, 50 and 100 ppm lithium standards to capture the depressed response due to background interference from the co-ions present. The relationships between ∆[Li] spiked and measured [Li] for the original brine and batches 1 to 11 brine after the 10-stage extraction are shown with the fitting correlations. These correlations were used to determine the ‘actual’ concentrations of lithium present in solution. Additionally, the loaded organic solvents from each stage for the first and last brine batch passing through the process were stripped (three times to ensure the complete stripping of the loaded metal ions) using water at aqueous to organic (A/O) ratio equal to 1. The stripping solutions were diluted and analyzed for the amount of metals loaded in the organic phase

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 solvent exchange 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.”
