American Lithium Files Updated Mineral Resource Technical Report on Falchani

Supporting 476% Increase in Measured & Indicated Lithium Resource

VANCOUVER, BRITISH COLUMBIA, December 15, 2023 – American Lithium Corp. (“American Lithium” or

the “Company”) (TSX-V:LI | Nasdaq: AMLI | Frankfurt: 5LA1) is pleased to announce it has filed the

independent National Instrument 43 -101 Technical Report on the updated Mineral Resource Estimate

(“MRE”) for the Falchani Lithium Project (“Falchani”) located in Southwestern Peru and as announced on

October 31, 2023. The MRE and Technical Report were completed by Stantec Consulting Services Inc.

(“Stantec”), which established a much larger lithium resource base which will form the basis of an updated

preliminary economic assessment on the Falchani (“PEA”). The MRE has been incorporated into the Mine

Plan within the PEA, which is currently being finalized by DRA Global and will be announced shortly.

Key Highlights of Technical Report

➢ Measured + Indicated Resource (“M&I”) increases 476% from previous 2019 MRE;

➢ Measured Resource – 1.01 Million Tonnes (“Mt”) Lithium Carbonate Equivalent (“LCE”) ( 69 Mt @

2,792 parts per million (“ppm”) Lithium (“Li”));

➢ Indicated Resource – 4.52 Mt LCE (378 Mt @ 2,251 ppm Li);

➢ M&I Resource – 5.53 Mt LCE (447 Mt @ 2,327 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 LC selling price;

➢ At 1,000 ppm cut -off, also used in previous MRE. the updated M&I 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 continue to make excellent progress at Falchani and

this very large increase and reclassification of the Falchani Resource follows a very successful drill program

completed Q3, 2023. With the Deposit still open in numerous directions, we expect the scale of the Project

and the size of the Resource to continue to grow. The increase in resource feeds directly into the updated

PEA on Falchani, which is currently being finalized and will be released shortly, and into the ongoing Pre-

Feasibility Study.”
