VANCOUVER, Oct. 22, 2019 /CNW/ - Advantage Lithium Corp. (TSX Venture AAL) ("Advantage" or the "Company") is pleased to announce the results of a Pre-Feasibility Study ("PFS") based on production of Battery Grade Lithium Carbonate from a 25 ktpa nameplate capacity stand-alone plant located at its Cauchari JV in the province of Jujuy, Argentina. The PFS was prepared by Worley, Chile S.A. ("Worley"), a leading integrated independent engineering services firm with extensive experience in the design and construction of lithium brine projects in Argentina and Chile. FloSolutions SpA (FloSolutions) prepared the resource and reserve estimates for the PFS as summarised in this announcement.
Callum Grant, Interim CEO commented "The PFS now demonstrates that we have a solid project to a much improved level of confidence compared to the 2018 Preliminary Economic Assessment. Not only have we doubled the resource but more importantly those resources were upgraded to Measured and Indicated categories earlier in 2019. Now we have a Proven and Probable Mineral Reserve demonstrating the economic viability of the asset to support long-life supply of battery-grade Lithium Carbonate to the EV market; we're now at a different level where the value of the asset is clear.
Based on these encouraging results, our intention is to engage quickly with several parties who have expressed an interest in making an investment decision in the Cauchari JV project."

Deferred Capital Expenditure
The Project economic evaluation includes additional capital expenditure totalling US$ 157.5 million for expansion of the well field production from the initial NW sector into the SE sector along with increasing the evaporation pond area and additional salt harvesting machinery purchasing, in order to maintain stable lithium production over the life of mine. The deferred capital expenditure is planned for year 5 and year 9.
In addition, the Project includes sustaining capital expenditure of US$ 2.7 million per year and a peak working capital expenditure of US$ 33.5 million.
The Operating Costs estimates are also divided into Direct Costs and Indirect Costs, as shown below in table 3. This table reflects the variations in costs produced by the effect of expanding the well field production from the initial NW sector into the SE sector along with increasing the evaporation pond area.
The life of mine (LOM) average Direct Costs associated with the brine extraction and processing operations are estimated at US$ 3,493 per tonne of lithium carbonate. Indirect Costs include G&A and some local costs and are estimated at $67 per tonne for a Total OPEX average of US$ 3,560 per tonne.

lithium is converted to lithium carbonate equivalent (LCE) with a conversion factor of 5.32. Potassium is converted to potash with a conversion factor of 1.91
The resource estimation work was followed by the development of a three-dimensional numerical flow and transport model (FEFLOW Code) to evaluate options for wellfield configurations and brine production schedules and to develop a Reserve Estimate. The modeling work was carried out by the DHI Group1 under supervision of FloSolutions. Table 5 summarizes the Reserve Estimate for the Cauchari JV Project.
Table 5: Cauchari JV Project Lithium Reserve Estimate (September 15, 2019)
Notes to the Cauchari JV Lithium Reserve Estimate:
Effective date of this Reserve Estimate is: 15 September 2019.
The Lithium Reserve Estimate represents the lithium contained in the brine produced by the wellfields as input to the evaporation ponds. Brine production initiates in Year 1 from wells located in the NW Sector. In year 9, brine production switches across to the SE Sector of the Project.
The PFS wellfield configuration maintains LOM Li concentrations from all pumping wells above 350 mg/l, which is considered a practical cut-off grade for the lithium reserve estimate.
Approximately 21 percent of M+I Resources are converted to Total Reserves.
Potential environmental effects of pumping have not been comprehensively analysed at the PFS stage. Additional evaluation of potential environmental effects will be done as part of the next stage of evaluation.
Additional hydrogeological test work will be required in the next stage of evaluation to adequately verify the quantification of hydraulic parameters in the Archibarca fan area and in the Lower Sand unit as indicated by the sensitivity analysis carried out on the model results.
Mineral Reserves are derived from and included within the M&I resources in the resource Table 4 above.
Indicated Resources of 894,000t LCE contained in the West Fan Unit are not included in this PFS production profile. There is a reasonable prospect that through additional hydrogeological test work Inferred Resources in the Lower Sand Units will be converted to M+I Resources.
Numbers may not add due to rounding.

The process is unchanged from the PEA design and scaled up due to the increased production capability resulting from expanded lithium resource. Brine is pumped to the surface and directed to a series of evaporation ponds and since Cauchari brine is a low Mg/Li type of brine, the magnesium is removed with slaked lime as magnesium hydroxide. The brine also contains sufficient sulphate in order to precipitate the calcium as gypsum liberated from the lime. During the evaporation process principally halite salts, glaserite and some sylvite and borate salts are crystalized generating a concentrated lithium solution suitable to precipitate lithium carbonate. The concentrated lithium solution is further polished in order to reduce the calcium, magnesium and other metal levels in order to produce an industrial technical grade, which is then re-crystallized in order to make a very pure battery grade product. Battery grade lithium carbonate product is planned to be transported to Antofagasta, Chile for shipment overseas. Production is modelled to start in 2022 with the plant ramping up over 3 years to a steady state of 25 ktpa lithium carbonate.
Production Profile Over Life Of Mine
Advantage Lithium's marketing and product development strategy has been established to meet customer specifications and develop QA/QC protocols for offtake arrangements to achieve Battery Grade as the operation ramps up.
The production mix and profile used in the cash flow model during the ramp-up and operational life is as follows:
Table 6: LCE Production Profile2 (tonnes per annum)
Note 2: based on recovery factor of 66% from brine produced from wellfield bore to final product
The operation plan for the PFS is based on the extraction of the lithium-rich brine by a conventional wellfield with pump installations and proven processing techniques. This has been simulated over the life of mine by FloSolutions, resulting in the Reserve Estimate, summarised in table 5 above.
The Reserve Estimate represents the lithium contained in the brine produced by the wellfields as input to the evaporation ponds. Brine production initiates in Year 1 from wells located in the NW Sector. In year 9, brine production switches across to the SE Sector of the Project until year 31 when currently defined reserves are depleted.
Lithium Markets and Price
A marketing and product pricing study, used in the project economic analysis, was completed by Roskill, UK an independent marketing consultant engaged by Advantage Lithium.
Project design, production and cost parameters were input to the Worley Discounted Cash Flow Model for the PFS. Table 7 summarises the model results based on discount factors 6%, 8% and 10% with mid-range 8% selected as the base case:
Table 7: Economic Evaluation Results
Project economic evaluation incorporates current Argentinian federal and provincial fiscal tax legislation and royalties, including assumptions regarding provincial participation, to be confirmed during the next stage of development.
The economic analysis is based on brine grades and lithium volume estimated from the company's updated Resource and Reserve Estimates used to develop the production plan.
A weighted average price of US$ 12,166 per tonne of lithium carbonate Battery Grade was used over the life of mine.
An NI 43-101 report is required to be filed, in conjunction with the disclosure of the PFS in this news release, within 45 days.
