American Lithium Announces Positive Preliminary Economic Assessment for TLC, Base Case After-tax NPV8% US$3.26 Billion & After-tax IRR of 27.5%

Globe Newswire 1-Feb-2023 7:00 AM

VANCOUVER, British Columbia, Feb. 01, 2023 (GLOBE NEWSWIRE) -- American Lithium Corp. ("American Lithium" or the "Company") (TSXV:LI, NASDAQ:AMLI, Frankfurt:5LA1))) is pleased to announce the results of its maiden Preliminary Economic Assessment ("PEA") for the Tonopah Lithium Claims ("TLC") project located in the Esmerelda lithium district northwest of Tonopah, Nevada. This independent PEA was completed jointly by DRA Global and Stantec Consulting Ltd. ("Stantec") and demonstrates that the TLC project has the potential to become a substantial, long-life producer of low-cost lithium carbonate ("LCE" or "Li₂CO₃") with the potential to produce either battery grade LCE or lithium hydroxide ("LiOH"). The PEA base case envisions an initial 4.4 Million tonnes per annum ("Mtpa") processing throughput expanding to 8.8Mtpa. The PEA alternative case is identical, but with added production of high purity magnesium sulfate as a by-product over life of operations. Unless otherwise stated, all dollar figures are in US currency.

TLC PEA Highlights (Base Case – Ramp-up Production Li only production):

• Pre-tax Net Present Value ("NPV")_8% $3.64 billion at $20,000/tonne ("t") LCE
• After-tax NPV_8% $3.26 billion at $20,000/t LCE
• Pre-tax Internal Rate of Return ("IRR") of 28.8%
• After-tax IRR of 27.5%
• PEA mine and processing plan produces 1.46 Mt LCE LOM over 40 years
• Pre-tax initial capital payback period 3.6 years; after-tax payback 3.8 years
• Average LOM annual pre-tax cash flow: $435 million; annual after tax cash flow: $396 million
• Initial Capital Costs ("Capex") estimated at $819 million
• Total Capex estimated at $1,431 million; Sustaining Capital estimated at $792 million
• Operating cost ("Opex") estimated at $7443/t LCE inclusive of power credits

Simon Clarke, CEO of American Lithium, states, "We are extremely pleased to announce a very robust maiden PEA for TLC. Our team has worked hard and spent considerable time getting an in-depth understanding of TLC mineralization and the best way to recover high purity lithium utilizing conventional processing methods with the latest techniques and best in class plant and equipment. A significant portion of the processing work has been done to pre-feasibility levels as we believe this will help us move quickly through the next phases of development. At 99.4% LCE purity, TLC offers the capability to produce either battery grade lithium carbonate or hydroxide with minimal additional refining.

In this PEA, we showcase a long mine-life utilizing only the highest-grade sections of the deposit, with the potential for additional production ramp-up and mine life utilizing our mid-grade and lower grade sections. Not only are the economics very strong for high purity lithium production, but TLC also has the potential to produce high purity magnesium sulfates as by-products for agriculture and other end uses. As shown in the PEA, even assuming conservative pricing, these by-products can add significant economic value. At the same time, we have focused our work on ensuring we continue to minimize environmental impacts and water usage in the mining, processing and production of lithium from TLC."

TLC PEA Highlights (Alternate Case – Ramp-Up Production Li + Magnesium Sulfate production):

• Identical LCE production scenario, but with added LOM average production of 1,681,856 tpa of magnesium sulfate ("MgSO₄" - monohydrate and heptahydrate) by-products;
• Pre-tax Net Present Value ("NPV")_8% $6.06 billion at $20,000/t LCE & $150/t MgSO₄;
• After-tax NPV_8% $5.16 billion at $20,000/t LCE & $150/t MgSO₄;
• Pre-tax Internal Rate of Return ("IRR") of 38.6%
• After-tax IRR of 36.0%
• Pre-tax initial capital payback period 3.5 years; after-tax payback 3.7 years
• Average LOM pre-tax annual cash flow: $684 million; annual after tax cash flow: $591 million
• Initial Capital Costs ("Capex") estimated at $827 million
• Total Capex estimated at $1439 million; Sustaining Capital estimated at $763 million
• Operating cost ("Opex") estimated at $7443/t LCE inclusive of power credits
• Operating cost ("Opex") estimated at $817/t LCE, inclusive of power & MgSO₄ credits
• PEA mine plan produces 1.46 Mt LCE and 64.9 Mt MgSO₄ LOM over 40 years

Mine Life & Production

• Simple truck and shovel open pit mining of the shallow resource underpins the scalable, long-life, lithium project producing approximately 24,000 tpa LCE over Years 1-6 expanding to 48,000 tpa LCE production for Years 7-19 years when mining ceases. Rehandling of the >1,000 parts per million ("ppm") stockpile allows production to continue for Years 20-40.
• Average LOM Production of approximately 38,000 tpa LCE for 40 years.
• Targeted 1,400 ppm Li average feed grade pit-constrained resource supports mining for 19 years and processing >1,000 ppm Li stockpile for an additional 21 years.
• 1,400 ppm feed material beneficiation increases the head grade to leaching to 2,000 ppm Li.
• LOM Strip Ratio (Waste:Ore) of 0.93:1 with a maximum final pit depth of ~325-350', well above the water table depth.
• Where possible progressive reclamation of mining areas is planned along with in-pit back-filling of waste rock and filtered tailings.
• Sulfuric acid leaching using industry standard techniques and flowsheet produces high purity lithium carbonate to enable the production of battery grade LCE or LiOH.
  
  
  • PEA study estimates that for an additional $100M (Installed) Capex, and $406/t LCE Opex, a final conversion and refining processing step will enable the production of battery grade LiOH; or
  • End users have the flexibility of acquiring high purity LCE from TLC and converting it themselves to whichever product is required.

• Magnesium sulphate (monohydrate) is an increasingly important fertilizer add-on product with a large and growing global market. High-purity hydrated products (heptahydrate & epsom salts) are used in the food, personal care and water quality industries.
  

Table 1 – TLC Project PEA Key Highlights

Notes:

1. Production: base case is 2 phases, 4.4Mtpa and 8.8Mtpa throughput; alternative case is identical, but with production of magnesium sulfate co-product over life of operations.
2. Includes all operating expenditures with credit for excess power and revenue from MgSO4 production as offset to Unit LCE Opex, the estimate is expected to fall within an accuracy level of ±30%.
3. Includes 10% contingency on process plant capital costs, 10% contingency is included in the tailings and infrastructure costs, and closure costs (LOM).
4. Tax calculation estimates were completed by Mining Tax Plan LLP, and include Federal Taxes, all Nevada State taxes and royalties and Nye County Property tax estimates, and available producer tax credits.

Sensitivities

The project is most sensitive to LCE price and process costs, but relatively far less sensitive to capital costs and mining costs, in descending order of affect (see Table 2, and Figures 1 and 2, below).

Flat 24,000 t LCE Production Scenarios

As part of the PEA modeling and design work, DRA Global and Stantec were also requested to evaluate flat 24,000 t/year LCE production scenarios without any production ramp-up using the identical 1,400 ppm Li feed scenario. The flat scenarios both have 20 years of mining followed by processing of stockpiled material for Years 21 to 36.

The two additional scenarios are as follows:

• Case 3: Flat 24 kt/a LCE – Stand-alone Li-only production
• Case 4: Flat 24 kt/a LCE – Li and Magnesium Sulfate co-production

Cautionary Note Regarding Macusani Concessions
Thirty-two of the 169 concessions held by American Lithium's subsidiary Macusani, are currently subject to Administrative and Judicial processes (together, the "Processes") in Peru to overturn resolutions issued by INGEMMET and the Mining Council of MINEM in February 2019 and July 2019, respectively, which declared Macusani's title to 32 of the concessions invalid due to late receipt of the annual validity payments. In November 2019, Macusani applied for injunctive relief on 32 concessions in a Court in Lima, Peru and was successful in obtaining such an injunction on 17 of the concessions including three of the four concessions included in the Macusani Uranium Project PEA. The grant of the Precautionary Measure (Medida Cautelar) has restored the title, rights and validity of those 17 concessions to Macusani until a final decision is obtained at the last stage of the judicial process. A Precautionary Measure application was made at the same time for the remaining 15 concessions and was ultimately granted by a Court in Lima, Peru on March 2, 2021 which has also restored the title, rights and validity of those 15 remaining concessions to Macusani, with the result being that all 32 concessions are now protected by Precautionary Measure (Medida Cautelar) until a final decision on this matter is obtained at the last stage of the judicial process. The favourable judge's ruling confirming title to all 32 concessions from November 3, 2021 represents the final stage of the current judicial process. However, this ruling has recently been appealed by MINEM and INGEMMET. American Lithium has no assurance that the outcome of these appeals will be in the Company's favour.
