Sigma Lithium Corporation has significantly advanced its feasibility study for the Phase 2 Production, contemplating potentially doubling the Project's total capacity to 440,000 tons per year. The company and Primero completed all the metallurgical and variability prefeasibility test work at SGS Lakesfield in Canada with the aim of customizing a flowsheet to process the spodumene from the Project's second mine. The DMS metallurgical testing achieved remarkable 60.7% Li2O recoveries, producing a battery grade concentrate of 6.11% Li2O. High recoveries are a result of the Second Mine having exceptional mineralization, similar to the First Mine, with large crystals of coarse spodumene. The results demonstrate that the spodumene from the Second Mine can be successfully processed in an environmentally friendly DMS plant, with similar flowsheet to the Production Plant for the First Mine. The company completed all field work for the preparation of Phase 2 Production prefeasibility study, including geotechnical drilling and hydrogeological analysis. Additional drilling continues on the Second Mine seeking to both increase the mineral resource and to strengthen the geological data for the reserve block model (mining plan design). The Company is currently working on the mining plan and final geotechnical modelling of the Second Mine. The company completed a preliminary economic assessment for Phase 2 Production, projecting mining an average of 1.68Mt per year during approximately 12.7 years of projected mine life, which was included in an updated feasibility study report filed on SEDAR on July 15, 2021. Projects significant economies of scale for Phase 2 Production, expected to result from the low Capex of adding a second environmentally friendly processing line and vertically integrating it to the Second Mine and to the Production Plant. The company is accelerating its exploration activities in the areas covered by its portfolio of mineral rights to rapidly increase the scale of the Project's estimated mineral resources by the first quarter of 2022 with the goal to further: Increase the Projected mine life at the expanded production levels of 440,000 tons per year during, Phase 1 and 2 productions. Increase production output after 2024 in a third production phase should EV penetration growth continue to accelerate, and lithium demand forecasts continue to demonstrate strength. Determine the ultimate potential of the Project's mineralization while demonstrating its uniqueness and high quality.
