Millennial Lithium Corp. Provides Progress Update on the Pastos Grandes Project, Argentina

Farhad Abasov, President and CEO commented "We are very pleased with the progress to date at our Pastos Grandes Project.  The commissioning of the pilot plant facility will be an important milestone for the Company as we will produce battery grade lithium carbonate by basically duplication of the commercial design for the company’s 24,000 tonne per year lithium carbonate plant outlined in the Feasibility Study.  On the corporate level, the Company is encouraged by the consent of the various National, Provincial and local government entities concerning our application for the Fiscal Stability protection allowing us to be confident in government support for our project and the mining sector in general. The Company is also actively advancing financing, offtake and other strategic talks with large industry players.”

The liming plant at Millennial’s pilot pond complex is fully operational and treating up to 100 m³ of brine per day, directing the partially purified brine to a large holding pond for concentration of the lithium in preparation for treatment at the Company’s pilot plant facility.  The liming operation has been successful in reducing the sulphate and magnesium content of the brine and lithium plant feed grade is expected to be reached by December, 2019.

The pilot plant facility is currently under construction and is expected to treat plant grade brine in December, 2019.  The pilot plant is planned to produce approximately 3 tonnes per month of battery grade lithium carbonate and includes a final bicarbonation purification stage to ensure consistent production of battery grade lithium carbonate.  All material components including the solvent extraction system for the removal of boron, reactors for primary and secondary carbonation, ion exchange units and final bicarbonation reactors as well as a reverse osmosis water purification system are on site and assembly and construction are underway.  All electrical systems are in place and the pilot plant complex will be powered by the Company’s solar hybrid generating system.

To support the Feasibility Study and to gain additional hydrogeological information a long term constant rate pumping test of 15 days was completed at well PGPW16-01.  Well PGPW16-01 is 358m deep and employs 10” casing to a depth of 100m and 6” casing from 100m to 351m.  Well PGPW16-01 was drilled using mud rotary methods to a total depth of 358m. Drilled borehole diameter was 17” from surface to 125m depth and 13.5” to final depth. The well was completed with 10” blank PVC casing from 20m to 80 m and 6” slotted PVC casing from 100m to 351m.  The annular space between the borehole and the casing was filled with gravel pack.

A short term (60 hours) pumping test at PGPW16-01 was completed in 2017 at an average pumping rate of 27.7 litres/second (L/s) and yielded a robust transmissivity of 550 m²/day (see News Release dated July 10, 2017).  The long term constant rate pumping test at PGPW16-01, over a duration of 15 days in 2019, employed an average rate of 23.2 L/s and yielded a transmissivity of approx. 400 m²/day confirming the robust transmissivity measurements seen in the 2017 test.  Maximum drawdown was approximately 15m established after 15 minutes of pumping and then stabilized at this level for the entire 15 day pumping cycle confirming the robust flow of brine in the aquifer.  These results, along with the results from the 2017 testwork, support high flow rates in this part of the Pastos Grandes Project and future brinefield extraction well locations will be further studied to optimize performance in the detailed engineering phase of the project.

In addition to technical progress at Pastos Grandes, Millennial continues to advance the project at the corporate level.  Recent meetings with national Mining Secretary in Buenos Aires has confirmed that Millennial is covered under the benefits of Fiscal Stability as proscribed under the National Mining Law.  Fiscal Stability fixes the maximum overall tax rates and brings additional benefits for Millennial for a period of 30 years allowing for long term planning for the project and protection against potential future political fluctuations.  Millennial originally applied for Fiscal Stability in Q4 2018; meetings this week with the Mining Secretary and his deputies indicate final approval has been granted, with the delivery of the final signed resolution in early Q4 2019.
