Recent Drilling at TLC Significantly Expands Higher Grade, Near Surface Lithium Mineralization






American Lithium Corp. (TSX-V:LI) (Nasdaq:AMLI) (Frankfurt:5LA1) is pleased to announce results from 14 step out drill holes expanding the measured resource footprint at the Tonopah Lithium Project, located near the town of Tonopah, in Nevada. A total of 26 diamond core holes and 16 Reverse Circulation holes drilled in 2022 and 2023 will be added to the updated mineral resource block model and incorporated into an updated Mineral Resource Estimate on TLC.


The Company also announces it has commenced early work which will be used to support mine permitting applications following the completion of the pre-feasibility and associated study in H2, 2024. It has appointed SRK Consulting (U.S.) Inc. of Elko, Nevada to coordinate the preparation of a mine plan of Operations with the BLM. Additionally, the Company has selected Nexus Environmental Consultants Inc. of Reno, Nevada to perform biological baseline studies in support of the Mine Plan of Operations application.


TLC Drilling Highlights

  • Post-resource drilling demonstrates continued expansion of TLC lithium deposit and continuity with significant intervals of claystone Lithium (“Li”) mineralization >1,000 ppm Li at shallow depths;
  • Extension of measured resource footprint in all directions (see Figure 1);
  • 73.1 metres averaging 1,148 ppm Li in TLC-2222C between 17.1-90.2 m downhole with up to 1,843 ppm Li over 1.5 m;
  • 81.4 m averaging 1,135 ppm Li in TLC-2321C between 27.1-108.5 m downhole with up to 2,127 ppm Li over 1.5 m;
  • 80.8 m averaging 1,090 ppm Li in TLC-2242 between 3.0-83.8 m downhole with up to 2,008 ppm Li over 1.5 m; (see Tables of Select Diamond and RC Drill Hole Results);
  • Identification of additional shallow, high-grade lithium mineralization to the northeast should grow the MRE and positively impact project economics;
  • Drill results will further refine the pre-feasibility study mine plan; and
  • Data from all additional 42 drill holes has been sent to Stantec Consulting Inc. and will be incorporated into an updated MRE for the TLC Project.


Simon Clarke, CEO of American Lithium, states, “We continue to make excellent progress at TLC. Drill results from the remainder of our 2022 program and our expansion drilling in 2023 should add significantly to the very large existing Measured & Indicated Resource. In addition, the thick, shallow higher-grade sections added should further enhance robust project economics and will be reflected in an updated TLC mine plan in the PFS. Our confidence in the Project continues to grow and we have now launched work with SRK and Nexus which will feed into and help us fast-track the mine permitting process following completion of the PFS is in 2024.”


TLC Select Drill Hole – Details


RC drill holes:

  • TLC-2240, 2241 and 2242 as well as diamond drill holes TLC-2318C, 2320C, 2321C and 2333C were all drilled to the north of the existing Measured Resource footprint and extend the shallow, high grade lithium mineralization approximately 850 m to the north. TLC-2333C marks the northernmost mineralized hole with > 1,000 ppm Li intersected over appreciable thicknesses.


Diamond drill holes:

  • TLC-2222C was drilled in the west central resource area and essentially fills in a historic gap in the resource from 2000 era drilling that was not drilled deep enough.
  • TLC-2228C was drilled in the central northwestern area to fill in a statistical gap in the Measured resource footprint.
  • TLC-2320C and 2221C were drilled to in-fill an existing gap in Measured Resource footprint in the south-central resource area.
  • TLC-2218C and 2219C were drilled along the southeastern edge of the Measured resource footprint to extend and confirm lithium mineralization.
  • TLC-2213C was drilled on the eastern side of the project area, and extends the mineralized footprint with lower grade, but above cut-off grade Li mineralization marking the east central limit of the TLC Deposit high-grade footprint.

Quality Assurance, Quality Control and Data Verification


2022 Diamond drilling was conducted by First Drilling of Montrose, Colorado, and 2023 diamond drilling was completed by IG Drilling of Spanish Fork, Utah using large diameter, PQ-size and HQ-size drilling entirely vertical holes. Drill core samples are nominally 5-foot (1.53 m) and are cut longitudinally, and one half is cut a second time longitudinally with a diamond saw with one-quarter of the core placed in sealed bags and shipped to analytical laboratories.


Reverse Circulation drilling is being 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.


Samples were shipped to either American Assay Laboratories (AAL) in Sparks, Nevada for sample preparation, processing using 5-acid digest and ICP-MS multi-element analysis. Pulps and rejects are returned and retained by the Company. AAL is an ISO 9000 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, 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 for the essentially flat-lying, to gently dipping TLC host stratigraphy.

About American Lithium


American Lithium is actively engaged in the development of large-scale lithium projects within mining-friendly jurisdictions throughout the Americas. The Company is currently focused on enabling the shift to the new energy paradigm through the continued development of its strategically located TLC lithium project in the richly mineralized Esmeralda lithium district in Nevada, as well as continuing to advance its Falchani lithium and Macusani uranium development-stage projects in southeastern Peru. All three projects, TLC, Falchani and Macusani have been through robust preliminary economic assessments, exhibit strong significant expansion potential and enjoy strong community support. Pre-feasibility is advancing well TLC and Falchani.
