American Lithium Reports Highest Lithium Extraction to Date from TLC Claystones with 97.4% Extraction from Sulfuric Acid Leach

VANCOUVER, British Columbia, Aug. 25, 2021 (GLOBE NEWSWIRE) — American Lithium Corp. (“American Lithium” or the “Company”) (TSX-V:LI | OTCQB:LIACF | Frankfurt:5LA1) is pleased to announce the highest lithium extraction results to date, achieving 97.4% extraction utilizing warm sulfuric acid leach on Tonopah Lithium Claims (“TLC”) claystone mineralization.

Highlights:

• Latest TLC test work run by TECMMINE in Lima, Peru has achieved 97.4% lithium extraction using warm sulfuric acid leach, the highest results achieved to date from any recovery process.
• On-going test work for the sulfuric acid process route will continue to be optimized by varying leach time, acid concentration, temperature, solid-liquid ratios and grind/particle size.
• Metallurgical work on the TLC claystone mineralization continues to demonstrate amenability to three process options to extract lithium:
  • i) leaching with sulfuric acid (H₂SO₄) at 90°C (97.4% extraction);
  • ii) salt roasting followed by water leaching (initial 82% extraction); and
  • iii) leaching with hydrochloric acid (HCl) at 90°C (initial 95.1% extraction).
• Continued metallurgical work will aim to take each processing option through to the lithium carbonate and/or lithium hydroxide precipitation stage and to focus on optimizing all 3 processing options and related flow-sheet designs.
• Thereafter, the Company will select the best option to enable a robust Preliminary Economic Assessment (“PEA”) with economic benefits maximized and environmental impacts minimized.

Dr. Laurence Stefan, COO of American Lithium, stated, “We are pleased to have achieved the highest lithium extraction to date from TLC using simple sulfuric acid processing with almost the entire amount of lithium available extracted into sulfate solution. We continue to focus on optimizing the best process routes from both economic and environmental perspectives and, thereafter, to advance TLC through PEA towards future development.”

TLC Process Update
Process work has previously demonstrated that TLC claystones are amenable to rapid lithium extraction using warm sulfuric acid leaching, reaching 92% lithium extraction in 10 minutes. In addition, up to 82% lithium extraction has been achieved using salt roasting followed by water leaching (refer to previous news release, dated June 29, 2021). The latest test work run at TECMMINE achieved 97.4% lithium extraction into sulfate solution using H₂SO₄ at temperatures of 90⁰C with 60-minute leaching.

Optimization test work will continue into Fall 2021 using all three potential process options: hydrochloric acid, sulfuric acid as well as salt roasting/water leaching. American Lithium is committed to producing a world class process to supply cost competitive lithium products in an environmentally sound manner.

Stock Option Grant
The Company also announces the granting, subject to regulatory acceptance, of 500,000 incentive stock options to an advisor / consultant of the Company (the “Options”). The Options have a term of 5 years and are exercisable at a price of $1.81 per common share.

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. A final date for the last stage of the judicial process has not yet been set. If American Lithium’s subsidiary Macusani does not obtain a successful resolution of the Processes, its title to the concessions could be revoked.
