Gravity pre-concentration results in 52% grade increase for TLC Claystone retaining 88% Li in 60% mass

VANCOUVER, Sept. 09, 2021 - American Lithium Corp. ("American Lithium" or the "Company") (TSX-V:LI | OTCQB:LIACF | Frankfurt:5LA1) is pleased to announce positive pre-concentration upgrading results from Tonopah Lithium Claims ("TLC") claystone mineralization using Falcon continuous gravity concentrators with 88% of Lithium concentrated in 60% of the original mass - an upgrading factor of approximately 1.5.

Upgrading Highlights:

• Gravity concentration test work by TECMMINE, in consultation with Sepro Mineral Systems of Lima Peru, yielded excellent results using continuous gravity Falcon ("Falcon C") concentrators.
• Test work rapidly upgraded samples of TLC mineralization from 1,098 ppm Li to 1,671 ppm Li by retaining 88% of the lithium in 60% of the mass.
• On-going test work to further optimize the upgrading process including utilizing higher grade feed from planned drilling and bulk sampling at TLC.
• Processing material with significantly higher lithium concentrations should reduce costs through lower reagent consumption and reduced throughput, including the potential to reduce back-end processing plant requirements.

Dr. Laurence Stefan, COO of American Lithium, stated "The positive implications of upgrading cannot be overstated. We are extremely encouraged with the pre-concentration results achieved using commercially available gravity concentrators. By processing higher-grade lithium mineralization, a smaller plant footprint is possible, and processing becomes more efficient with the ability to minimize reagents and improve recoveries. We look forward to on-going test work using higher grade samples followed by metallurgical processing work on the higher grade concentrates produced."

TLC Upgrading Results

TECMMINE in Peru, in consultation with Sepro Mineral Systems Lima-based personnel have completed the first round of pre-concentration testing on TLC mineralization using Falcon "C" gravity concentrators.

Previous test work has demonstrated that gravity/physical concentration techniques are capable of upgrading TLC mineralization with the lithium preferentially reporting to the fine fraction in centrifuge tests (see Company news release dated March 23, 2021). The important fraction at TLC is not the "concentrate", but what is often considered "tails" in other commodities.

The latest and best results have concentrated 88% of lithium in 60% of the original mass through a simple process of crushing to 100% passing 500 μm (-0.5 mm) followed by a series of concentrator passes, re-pulping and scavenging.

The original head grade of the sample used was 1,098 ppm Li and was upgraded to 1,671 ppm Li in a process estimated to take less than 45 minutes in an industrial scale operation.

Sepro Mineral Systems' Falcon C continuous gravity concentrators are commercially available, off-the-shelf technology with models proven capable of handling large volumes of material suitable for bulk tonnage mining/processing operations.

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.
