[{"type":"text","content":" VANCOUVER, British Columbia, June 01, 2023 (GLOBE NEWSWIRE) -- Medaro Mining Corp. (CSE: MEDA OTC:MEDAF FWB:1ZY) (“Medaro” or the “Company”), a multi-faceted venture aimed at developing innovative hard rock lithium extraction technologies concurrent with its lithium focused exploration in Canada, is pleased to report new, extremely positive lithium recovery data derived from use of the company’s patent-pending spodumene processing technology (the “Technology”). In bench-scale laboratory tests performed recently under mild experimental conditions, application of the Technology culminated in extraction of greater than 95% of the lithium present in two very different β-spodumene compositions, one very pure (rich in lithium with low ppm concentrations of minor and trace elements), the other relatively impure (comparatively lithium-poor with significant ppm concentrations of minor and trace elements). Further explanation of the work, along with important analytical data and calculated values developed from it, appear below.

(Knoxville, Tennessee, USA)—were communicated to Medaro in Galbraith Report 147768 dated 5/9/23. 3The following analytically determined ppm concentrations of elements in the two unleached subsamples of the β-spodumene attest to its high purity: Al, 146,000 and 148,000 ppm; Si, 286,000 ...
