Millennial Lithium Corp. Provides a Corporate Update on Pilot Production Operations at its Pastos Grandes Project, Salta, Argentina

Farhad Abasov, President and CEO commented "Millennial is pleased with the progress at its pilot pond-lithium concentration facilities achieving a feed source with 3% Li and we are pleased with the initial progress of the process through the solvent extraction (SX) portion of the pilot plant. Our engineering team has performed very well identifying and addressing some minor issues and while some optimization of certain plant components has been necessary the overall impact on the project timeline has been minimal.   We look forward to producing battery grade lithium carbonate early in 2021 and finalizing our process design for the commercial plant.  Millennial remains well funded and continues in its financing efforts to advance development of the Pastos Grandes Project. Despite COVID-19 restrictions and slowdowns the Company has continued progressing its work with a number of off-takers and strategic investors. We are well on track with all our corporate programs.”

With help from the seasonal high evaporation rates a number of the Company’s concentration ponds in the evaporation pond string have reached 3% Li content and brine is being directed to the pilot plant for processing.  The initial processing stage, Solvent Extraction (SX), is designed to remove boron (B) from the brine.  The first batch processed contained an initial boron concentration of approx. 120 mg/l, well below modeled levels for the impurity; after the SX treatment the boron had reduced significantly to less than 5mg/L to 6 mg/L, well within the design range for the production flow sheet and pilot plant, indicating the SX system is working very well.  The main brine chemistry from the ponds, particularly B, K, Ca, Mg, and SO₄ concentrations are in line with the process and plant design parameters.

Minor pre-operational design adjustments to the primary brine purification carbonation reactors, filtering systems, the main lithium carbonate precipitation reactor, and the CO₂ purification system are ongoing and resulted in the replacement of several components to optimize recoveries.  Optimization of reactors and tanks is planned for completion by the end of Q4, 2020 with the production of battery grade lithium carbonate now scheduled for Q1, 2021. Upgrades and infrastructure improvements at the Company’s ICP lab on site have also been completed to ensure accurate analytical data for the processed brine and solids.  Millennial is continuing the pilot plant ramp-up with a significant staffing increase, including retaining experienced process engineers, supervisors and operators as well as additional lab staff and an expanded liming plant work force.  As part of the Company’s corporate initiative to develop people within the Company and the local communities, staff continue to train and educate operators and facilitate plant operation with the end-goal of providing fully qualified staff prepared for future commercial operation.  A comprehensive Health, Safety and Environmental protocol and training program has been implemented for all stages of the plant.
