American Lithium Announces 476% Increase in Measured + Indicated Lithium
Resources at Falchani - Adds K, Cs and Rb to Block Model
VANCOUVER, BRITISH COLUMBIA, October 31, 2023 - American Lithium Corp. ("American Lithium" or the "Company") (TSX-V:LI | NASDAQ:AMLI | Frankfurt:5LA1) is pleased to announce an updated Mineral Resource Estimate ("MRE") that significantly increases the contained lithium ("Li") for the Falchani Lithium deposit ("Falchani") located in Puno, southwestern Peru from the previous March 2019 MRE. The updated MRE update was completed by Stantec Consulting Services Inc. ("Stantec") as part of the process of updating the preliminary economic assessment ("PEA") for Falchani and will be incorporated into the mine plan within the updated PEA. DRA Global (Lead Engineer for the updated PEA and PFS on Falchani) is now finalizing the updated PEA with completion expected during November.
Stantec is preparing a NI-43-101 Technical Report for the updated Falchani Project MRE which is expected to be published within 45 days.
Highlights: (see Table 1 - New Falchani MRE and Table 2 - Original Falchani MRE)

• Measured + Indicated - 5.53 million tonnes ("Mt") Lithium Carbonate Equivalent ("LCE") (447 Mt @ 2,327 ppm Li) an increase of 476%;
o Measured Resource - 1.01 Mt LCE (69 Mt @ 2,792 ppm Li);
o Indicated Resource - 4.52 Mt LCE (378 Mt @ 2,251 ppm Li);
• Inferred Resource - 3.99 Mt LCE (506 Mt @ 1,481 ppm Li);
• Base Case cut-off has been lowered to 600 ppm Li from previous 1,000 ppm cutoff based on strong project economics specifically updated operating costs and $20,000/tonne ("t") LC selling price;
• At 1,000 ppm cut-off, the updated Measured + Indicated Resource is 5.32 Mt LCE versus 0.96 Mt LCE from previous March 2019 MRE - an increase of 455%; and
• Increased size and grade of resource supports long production potential at Falchani.
Simon Clarke, CEO of American Lithium states, "We are extremely pleased with the results of our EIA drill program and the very large increase in resources at Falchani which includes, doubling the contained lithium. Falchani is now one of the largest hard rock lithium projects globally with the ability to produce high purity battery grade lithium carbonate. The inclusion of potassium, cesium and rubidium in the resource block model provides the opportunity to include Sulfate of Potash (SOP) and Cs-Rb potential by-products into future financial modelling of Falchani. DRA Global has commenced mine plan modelling and updating capital and operating costs for the updated PEA, expected within the next several weeks. These strong and strategic updates to the PEA will enable us to fast-track the completion of the PFS."

Mineral Resource Estimation Calculation Methodology
The geologic model used for reporting of lithium resources was developed using Seequent's Leapfrog geological modelling software, Leapfrog Geo version 2023.1. and Hexagon Mining's resource modelling and mine planning software, MinePlan version 16.1.1. The geologic model from which lithium resources are reported is a 3D block model developed using the World Geodetic System (WGS) 1984 UTM Zone 19S and is in metric units. Block size is 20m-X, 20m-Y and 5m-Z. Modeling method and approach is development of a multiple ore percent standard block model with interpretation of geologic controls on mineralization based on exploration data. A significant new addition to the resource is the recognition of an additional mineralized basement lithological unit below the lower mineralized volcanic breccia horizon.
A base case lithium resource cut-off grade has been calculated based on the economics of a medium size (100 Mtpa) run-of-mine (ROM) surface mining operation. Processing of the mineralized material would be onsite extracting lithium from volcanic tuffs, volcanic breccias and a coarse felsic intrusion using an acid digestion method. Resources are reported from within an economic pit shell at 45-degree constant slope using Hexagon mining pseudoflow algorithm. Maximum pit depth is limited to 300 metres ("m") below surface. No underground mining is considered.
The following mining, processing, royalty, and recovery costs, in US$, were used to derive a base case cut-off grade to produce a lithium carbonate (Li2CO3) equivalent product:
- Mining costs US$2.5/tonne;
- Processing costs US$50/tonne;
- General and administration US$1/tonne; and processing recovery of 80%.
Revenue from a lithium carbonate product is estimated to be US$20,000/t for the cutoff grade calculation. Using the above inputs and Li2CO3: Li ratio of 5.32, a base case cut-off grade for lithium is estimated to be 600 ppm. The base case cut-off grade of 600 ppm lithium is lower than the previous MRE (Riordan et al., 2020) cut-off grade of 1,000 ppm lithium, mostly due to an increase in the assumed LC price.
Resource Update Effective Date - October 30, 2023:
Exploration Data:
◾ 3,075 m of additional drilling from 15 drill holes (2022 to 2023);
◾ New total of 12,317 m from 67 drill holes from 35 platforms (2017 to 2023);
◾ 15 vertical piezometer core holes from 10 platforms (2022 to 2023);
◾ 52 Core holes (vertical and inclined) from 25 platforms (2017 to 2019).
Quality Assurance, Quality Control and Data Verification
Diamond drilling is being conducted using Company-owned drill rigs with local contract personnel. Drill core samples are cut longitudinally with a diamond saw, with one-half of the core placed in sealed bags and shipped to Certimin's sample analytical laboratory in Lima for sample preparation, processing and ICP-MS/OES multi-element analysis. Certimin is an ISO 9000 certified assay laboratory. The program is designed to include a comprehensive analytical quality assurance and control routine comprising the systematic use of Company inserted standards, blanks and field duplicate samples, internal laboratory standards and has also included check analyses at other accredited laboratories. Downhole thicknesses for vertical drill holes are considered accurate true thickness intersections.

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.
