American Lithium Reports Successful Resource Conversion with Significant Increase in Measured Resources at TLC, up 47% to 6.17 Mt contained LCE

Rhea-AI Summary

American Lithium Corp has announced an updated Mineral Resource Estimate (MRE) for its Tonopah Lithium Claims (TLC) project in Nevada. The update shows a significant 47% increase in Measured Resources to 6.17 Mt of Lithium Carbonate Equivalent (LCE), based on 44 additional drill holes since January 2023.

Key resource changes include:

• Measured Resource: 6.17 Mt LCE (1,365 Mt @ 849 ppm Li)
• Indicated Resource: 2.39 Mt LCE (553 Mt @ 808 ppm Li), down 48%

VANCOUVER, British Columbia, Feb. 27, 2025 (GLOBE NEWSWIRE) -- American Lithium Corp. (“American Lithium” or the “Company”) (TSX-V:LI | OTCQX:AMLIF | Frankfurt:5LA1) is pleased to announce an updated Mineral Resource Estimate (“MRE”) for the Tonopah Lithium Claims (“TLC”) project, located in the Esmerelda lithium district northwest of Tonopah, Nevada. The updated MRE has successfully converted Indicated Resources to the Measured category, increasing Measured Resources 47% from the previous 2023 MRE at TLC. The resource block model has been further refined, increasing the confidence of the TLC resource. The vast majority of resources used in the 2024 PEA Mine Plan are now within the more reliable Measured Resource footprint.

The updated MRE was completed by Stantec Consulting Services Inc. of Salt Lake City, UT and is based on an additional 44 drill holes drilled since the previously filed January 2023 MRE.

Highlights: (see Table 1 February 2025 TLC MRE & Table 2 Previous January 2023 TLC MRE, below)
Link to: Figure 1 – TLC Project Updated Mineral Resource Block Outline and Drill Hole Location Map (also see below)

• Measured Resource – 6.17 Mt Lithium Carbonate Equivalent (“LCE”) (1,365 Mt @ 849 ppm Li); increase of 47% contained LCE versus 2023 MRE
• Indicated Resource – 2.39 Mt LCE (553 Mt @ 808 ppm Li); decrease of 48% versus 2023 MRE
• Measured + Indicated Resource – 8.56 Mt LCE (1,918 Mt @ 839 ppm Li); 3% decrease from 2023 MRE
• Inferred Resource – 1.44 Mt LCE (345 Mt @ 780 ppm Li); 22% decrease from 2023 MRE

American Lithium Interim CEO, Alex Tsakumis states: “We are very pleased with the newly established and upgraded Measured Resource footprint at TLC as it not only increases the resource confidence level in the Measured category but also represents the core of the 2024 PEA Mine Plan. Our focus remains on diligently and prudently advancing our projects as we prepare for an anticipated recovery in the battery metals market.”

Mineral Resource Estimation Calculation Methodology
The geologic model used for reporting of lithium resources was developed using Hexagon Mining’s geological 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 Nevada State Plane Central Zone NAD83 coordinate system and U.S. customary units. Block size is 50ft-X, 50ft-Y and 20ft-Z. Modeling method and approach is similar to that described in the prior Technical Report (Loveday and Kester, 2023) but with a re-interpretation of geologic controls on mineralization using the additional exploration drilling and geophysical data.

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 that does not require blasting. Processing of the mineralized material would be onsite extracting lithium from claystone 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 1,000 feet (304.8 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$3/tonne;
• Processing costs US$49/tonne;
• Royalties US$1/tonne;
• General and administration US$1/tonne; and Processing recovery 90%.

Revenue from a lithium carbonate product is estimated to be US$20,000/tonne 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 500 ppm, rounded from 501 ppm. The base case cut-off grade of 500 ppm lithium is the same as the prior (Loveday and Kester, 2023) Mineral Resource Estimate (“MRE”) using the same cost assumptions as the prior MRE.

The updated base case MRE represents an increase of 47% Li₂CO₃ equivalent tonnes in the Measured Category, a decrease of 48% for the Indicated category when compared to the prior MRE (both at 500 ppm Li cutoff). Inferred Li₂CO₃ equivalent resources have decreased by 22% percent when compared to the prior MRE for the base case.

Resource Estimate Parameters:

• Resource Update Effective Date – February 7, 2023:
  • 44 new drill holes (2022 to 2023) added to current MRE (16 RC and 28 Diamond)
  • 82 drill holes (2019 to 2022 in previous MRE)
    

Quality Assurance, Quality Control and Data Verification

Diamond drilling was conducted by First Drilling of Montrose, Colorado using large diameter, PQ-size, drilling entirely vertical holes in 2022. In 2023 eight (8) additional diamond cores were drilled by IG Drilling
of Payson, Utah using drill rig CS-14 using either a PQ or HQ diameter drill bit. Drill core samples are nominally 5-foot (1.53 m) length and are cut longitudinally, and one half of the HQ-size core, or one quarter of PQ size core is placed in sealed bags and shipped to analytical laboratories.

Reverse Circulation (RC) drilling was conducted by Harris Exploration Drilling and Associates Inc., of Fallon, Nevada with 5.5-inch diameter face centred bit on vertical drill holes. Sampling was conducted using a riffle splitter or a cyclone splitter depending on the moisture content of the sampled material. Sampling was conducted over 5-foot (1.52m) intervals with individual samples placed in sealed bags and transported to the respective analytical labs. In 2023 three (3) RC holes were
drilled by Harris’s Canterra Rig using 5.5” diameter.

Samples were shipped to American Assay Laboratories (AAL) in Sparks, Nevada for sample preparation, processing and ICP-MS multi-element analysis. Pulps and rejects are returned and retained by the Company. AAL is an ISO/IEC 17025 certified assay laboratory. The QA/QC program includes a comprehensive analytical quality assurance and control routine comprising the systematic use of Company inserted standards, blanks and field duplicate samples, and internal laboratory QA/QC standard operating procedures. Downhole lengths (depths) for vertical drill holes are considered accurate true depth intersections for the essentially flat-lying, to gently dipping TLC host stratigraphy.

Cautionary Note Regarding 32 Concessions

Thirty-two of the one-hundred-seventy-four concessions comprising the Falchani and Macusani Projects are currently subject to Administrative and Judicial processes in Peru to overturn resolutions issued by INGEMMET and the Mining Council of MINEM in February 2019 and July 2019, respectively, which declared title to thirty-two concessions invalid due to late receipt of the annual validity payments.  On November 2, 2021, American Lithium was awarded a favorable ruling in regard to title to the concessions, but on November 26, 2021, appeals of the judicial ruling were lodged by INGEMMET and MINEM. A three-judge tribunal of Peru’s Superior Court unanimously upheld the ruling in a decision reported in November 2023. American Lithium was subsequently notified that INGEMMET and MINEM have filed petitions to the Supreme Court of Peru to assume jurisdiction in the proceedings. Given the precedent of the original ruling it is hoped that the Supreme Court will not assume jurisdiction; however, there is no assurance of the outcome at this time.
