PepinNini Minerals Ltd. reported very encouraging interim results from the lithium brine blending study underway in Chile, using brine from the company's leases on the Rincon and Incahuasi salares in Argentina. The study, which commenced in May 2021, uses 2,000 litres of brine collected from each salar that is transported to testing facilities in Chile and allowed to evaporate and concentrate. Three testing regimes are being applied in the study: Test 1 Blended brines; Test 2 Incahuasi brine; and Test 3 Rincon brine. After eight weeks of testing, a lithium ion concentration of 8,500 mg/kg was recorded for the blended brine, a level 14 times that of Incahuasi brine and seven times that of Rincon brine. Companies such as Orecobre at their Olaroz project(100km north) concentrate to 7,000 mg/kg. While the testing has another month to complete, the preliminary results suggest that the brine blending process is viable and highly effective. The blending of brine with a high concentration of sulphate from the Salar del Rincon with the brine of high concentration of calcium from the Salar de Incahuasi avoids the precipitation of lithium sulphate and reduces the calcium content. By using this difference between the brines, it is possible to obtain a higher concentration of lithium in the brine at a lower cost. Importantly it is industry best practice to conduct brine blending studies in order to evaluate and optimize future lithium chemical production.
