Drill-Ready Uranium Targets Added at Macusani with surface grab samples

averaging 18,270 ppm U (2.15% U3O8)

Exploration and Resource Expansion Drilling Planned

VANCOUVER, BRITISH COLUMBIA, September 28, 2021 – American Lithium Corp. (“American Lithium” or

the “Company”) (TSX-V:LI | OTCQB:LIACF | Frankfurt:5LA1) is pleased to announce positive prospecting,

mapping and sampling results from the Company’s Macusani Uranium Project (“Macusani”), located in

the Puno region in southeastern Peru, and to provide an update on upcoming drilling plans for the project.

Highlights:

• 2021 radiometric prospecting and sampling work has identified possible extensions to five existing

uranium deposits and three new anomalies for drill testing (see Figure 1 – Macusani Project Location

Map with new target areas highlighted, below);

• Results include over 90 gra b sample with grades ranging from a low of of 6.3 ppm U to a high of

377,400 ppm U (44.5% U3O8) with all samples averaging 18,270 ppm U (2.15% U3O8) 1;

• Drilling is planned at Macusani to expand existing uranium resources and to test for new deposits.

• Permitting process, including environmental permits and community access agreements have been

filed, with drilling anticipated to commence once exploration permit issued: and

Dr. Laurence Stefan, COO of American Lithium, states , “The results of the radiometric prospecting and

sampling program continue to confirm the exciting potential for further resource expansion at Macusani,

which is currently one of the largest undeveloped uranium project s globally. Our uranium mineral

concessions cover the majority of the entire Macusani Uranium District, which contains all known uranium

resources in Peru. We look forward to drill testing multiple targets starting next month.”

About Macusani Uranium Project:

Macusani is a low -capex, large -scale pre-development stage uranium project containing significant

measured, indicated and inferred uranium resources , and has an NPV(8%) of $603.1 million, IRR of 40.6%

and a 1.8 -year payback (all after -tax @ $50/lb U 3O8 selling price).2, 3 The Macusani project has a large

resource base with Indicated resources of 95.19 M tonnes grading 248 ppm U 3O8, containing 51.9 M lbs

U3O8 and Inferred Resources of 130.02 M tonnes grading 251 ppm U 3O8, containing 72.1 M lbs U 3O8.

Macusani is located approximately 25 kilometres away from the Company’s Falchani Lithium deposit.

Notes

1 Grab samples are selective, and the selected nature of such sampling does not necessarily reflect potential uranium contents

expected from future drill testing, but they do indicate the presence of uranium mineralization and mineralizing systems in the

surface rocks collected.

2"Macusani Project, Macusani, Peru, NI 43-101 Report – Preliminary Economic Assessment” prepared by Mr. Michael Short and

Mr. Thomas Apelt, of GBM Minerals Engineering Consultants Limited; Mr. David Young, of The Mineral Corporation; and Mr.

Mark Mounde, of Wardell Armstrong International Limited dated January 12, 2016.

3 Readers are cautioned that the PEA is preliminary in nature and includes inferred mineral resources that are considered too

speculative geologically to have the economic considerations applied to them that would enable them to be categorized as

mineral reserves. There is no certainty the results of the PEA will be realized. Mineral resources are not mineral reserves and do

not have demonstrated economic viability. Additional work is required to upgrade the mineral resources to mineral reserves. I n

addition, the mineral resource estimates could be materially affected by environmental, geotechnical, permitting, legal, title,

taxation, socio -political, marketing or other relevant factors, including the title to the 32 affected concessions that impact

approximately 30% of the uranium mineral resources at Macusani. See below “Cautionary Note Regarding Macusani

Concessions.”

Details:

Recently completed r adiometric prospecting , mapping and sampling w ork successfully generated

additional drill target areas on Macusani. This work has been integrated with previous exploration results

completed earlier in 2021 to form the basis of the upcoming diamond drill program, expected to

commence in October, subject to permitting being finalized.

The exploration work completed this season consisted of ~12,000 radiometric scintillometer station

readings coupled with the collection of over 90 outcrop sample stations with associated geological

observations. Radiometric prospecting was completed using SAIC Exploranium GS -135 Plus hand -held

spectrometers with sample station results recorded as counts per second (CPS) and map coordinates

recorded using handheld GPS. Additional site, soil and rock observations are also recorded at prospected

sites. Radiometric stations were completed initially on an approximately (~) 100 m by 100 m grid, which

was tightened to ~50 m by 50 m and further, to ~25 m by 25 m when anomalous radioactivity was

encountered to delineated fracture and disseminated uranium mineralization zones and trends.

CPS measurements from hand -held spectrometers and scintillometers measure radioactivity of certain

decay products of uranium, thorium and potassium, and are not necessarily a direct indication of uranium

contents. However, experience and previous equilibrium and geochemical reconciliation work completed

over the past 16 -year history of the Macusani conclude that CPS measurements from radiometric

prospecting can provide an indication of uranium mineralization with no thorium and minimal potassium

interference. Background radioactivity of the host rhyolite volcanic flows is usually <200 CPS. Over 90 grab

samples were collected from surface outcrop or sub -crop buried under thin soil cover from prospected

areas on the Macusani. Most sample sites had indications of radiometric or visible uranium mineralization,

with attempts to collect a representative sample of the observed outcrop/sub-crop, however, the selected

nature of such sampling does not necessarily reflect potential uranium contents expected from future drill

testing, but they do indicate the presence of uranium mineralization and mineralizing systems in the

surface rocks collected.

The samples range in uranium contents from a low of 6.3 ppm U to a high of 377,400 ppm U (44.5% U3O8).

The average of all samples collected and analyzed is 18,270 ppm U (2.15% U3O8).

Uranium mineralization identified along fractures and disseminated within the host rhyolite matrix were

collected using geological hammers with samples up to several kilograms placed in sealed bags for

shipping to analytical labs in Lima. Sample site map coordinates are recorded using hand -help GPS,

radiometric measurements recorded using handheld spectrometers as described previously, above, sites

and samples are described and photographed by Company geologists.

The results of radiometric prospecting, mapping and sampling reveal several positive trends in the

mineralized areas highlighted by the red stars in Figure 1.

Quality Assurance, Quality Control (“QA/QC”) and Data Verification

Radiometric prospecting is completed in a grid -pattern using SAIC Exploranium GS -135 Plus hand -held

spectrometers (maximum reading ~65,600) with periodic sample station results recorded as CPS . The

reader is cautioned that CPS measurements from hand-held spectrometers and scintillometers measure

radioactivity of certain decay products of uranium, thorium and potassium, and are not necessarily a

direct indication of uranium contents.

Outcrop grab samples are collected from expose d outcrop, with samples 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. Where Uranium contents exceed 10,000 ppm U (max detection limits for

ICP technique), the original sample solutions are diluted and re-analyzed using the same ICP-MS methods.

Certimin is an ISO 9000 certified assay laboratory. The selected grab samples are not necessarily

representative of the grades of mineralization hosted on the property. The Company’s Qualified Person,

Mr. Ted O’Connor, has verified the data disclosed, including radiometric prospecting and outcrop

sampling procedures and analytical data. The QA/QC program is designed to include a comprehensive

analytical qual ity assurance and control routine comprising the systematic use of Company inserted

standards, blanks and field duplicate samples, and internal laboratory standards.

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

the 32 of the concessions invalid due to la te receipt of the annual validity payment. Macusani successfully applied

for injunctive relief on 32 concessions in a Court in Lima, Peru, and the grant of the Precautionary Measures (Medida

Cautelar) has restored the title, rights and validity of those 3 2 concessions to Macusani until a final decision is

obtained in at the last stage of the judicial process. If American Lithium’s subsidiary Macusani does not obtain a

successful resolution of Processes, Macusani’s title to the concessions could be revoked.
