VANCOUVER, British Columbia, Jan. 09, 2023 (GLOBE NEWSWIRE) — American Lithium Corp. (“American Lithium” or the “Company”) (TSX-V:LI | OTCQB:LIACF | Frankfurt:5LA1) is pleased to announce results of confirmatory lithium leaching and lithium carbonate precipitation test work from Tonopah Lithium Claims (“TLC”) mineralization. The test work was completed at McClelland Laboratories in Reno, Nevada with lithium carbonate products analyzed at SGS Lakefield in Lakefield, Ontario. Similar expanded studies also continue at ANSTO in Australia. This test work supports the maiden Preliminary Economic Assessment (“PEA”) for the TLC project, which is in final phase of completion and expected to be released shortly.
Highlights: (see Table 1 – TLC Lithium Carbonate Chemical Analysis and Calculated Purity and Figure 1 – Photograph of TLC Lithium Carbonate product, below)
- Sulfuric acid leaching TLC claystone mineralization achieved 97.7% lithium extraction with short 2-hour leach time;
- Overall lithium recovery of at least 88.1% from leach through primary lithium carbonate precipitation including lithium losses of only 4.7% during leachate neutralization, 4.9% during impurity removal and crystallization/washing steps;
- Calculated Lithium Carbonate (“LC”) purity of 99.4% based on ICP-MS/ICP-OES chemical analyses of TLC primary lithium carbonate product at SGS Lakefield analytical laboratories prior to any additional refining steps;
- LC product requires an additional process step in the flow-sheet to remove remaining impurities (Potassium – K; Calcium – Ca) and produce battery-grade LC or Lithium Hydroxide;
- PEA will reflect work done to date, but process optimization work will continue
Simon Clarke, CEO of American Lithium states, “We are very pleased with the latest TLC lithium carbonate precipitation results and on-going optimization leach test work which has achieved very high lithium extraction, high overall lithium recoveries and extremely good lithium purity. This work forms key inputs into the maiden PEA for the TLC project, scheduled for release this month, and enables the completion of flow sheets to produce battery grade lithium carbonate and / or hydroxide. This marks yet another successful milestone for the project and team and capped off a year that saw significant positive achievements and results.”

Sulfuric Acid Leaching and Lithium Carbonate Precipitation Test Work – Details
Sulfuric acid leaching of TLC mineralization with lithium carbonate recovery was conducted at McClelland Laboratories in Reno, Nevada under the supervision of Jared Olson, VP Operations of McClelland Laboratories.
Test conditions were as follows: (See Table 2 – Circuit Simulation Testing Lithium Recoveries, below)
- 2 hour agitated atmospheric leaching using sulfuric acid at 90°C followed by filtration and residue rinsing achieved 97.7% lithium extraction.
- Leach solution neutralized with limestone and lime to remove iron and aluminum, followed by precipitate rinsing to recover entrained solution; completed with 95.2% recovery of lithium to filtrate and rinse solutions.
- Sulfate crystallization by evaporation and cooling followed by treatment with lime to remove remaining magnesium, with 94.7% lithium recovery.
- Calcium removal and lithium carbonate production by reaction with sodium carbonate. All products (precipitates and solutions) from these steps would be recycled in a commercial process, so no losses are considered from these steps.
- Global lithium recovery of 88.1%
- Lithium Carbonate product was sent to SGS Lakefield for ICP-MS/ICP-OES multi-element analysis. A calculated purity of 99.4% LCE was achieved without secondary refining steps.
- All processing steps were simulated by batch testing in open-cycle. Recycling of products was not simulated. These results should be verified by continuous and/or pilot testing with appropriate product recycling.
- *Process simulated by batch testing in an open cycle (i.e. without recycling any products). Lithium contained in products that would be recycled during commercial processing was considered recovered.
Process recovery and cumulative recovery through each step is presented in Table 2.

West Claim Block
The Company also announces that it has reached an agreement with certain arms-length vendors (the “Vendors”) to acquire a holding company which controls a series of eight lode mining claims (the “Claims”) located in Nye County, Nevada. The Claims are contiguous to the TLC project and will further improve access to the project from the west and control of the region immediately surrounding the project. In consideration for the acquisition, the Company has agreed to issue a total of 200,000 common shares to the Vendors.
All common shares issued to the Vendors will be subject to restrictions on resale for a period of four-months-and-one-day following issuance in accordance with applicable securities laws. No finders’ fees or commissions are owing in connection with the acquisition. Completion of the acquisition remains subject to the approval of the TSX Venture Exchange.

Cautionary Note Regarding Macusani Concessions
Thirty-two of the 151 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.
