American Lithium files TLC PEA Report Highlighting Potential for Excellent Project Economics
PFS for TLC immediately Launched with DRA Global; Bulk Sampling Commenced
VANCOUVER, BRITISH COLUMBIA, March 20, 2023 – American Lithium Corp. (“American Lithium” or the “Company”) (TSX-V:LI | NASDAQ:AMLI | Frankfurt:5LA1) announces it has filed an independent National Instrument 43-101 Technical Report (the “Report”) on the Preliminary Economic Assessment (“PEA”) for the Tonopah Lithium Claims (“TLC”) project located in the Esmerelda lithium district northwest of Tonopah, Nevada. Highlights of the PEA were previously announced on February 1, 2023. The PEA and accompanying Technical Report were completed by DRA Global and Stantec Consulting Services Inc. (“Stantec”) and demonstrate that the TLC project has the potential to become a substantial, long-life producer of low-cost, high purity lithium carbonate (“LCE”).
The Company also announces that it has engaged DRA Global as lead engineer for the TLC Preliminary Feasibility Study (“PFS”). As part of the initial PFS work, large diameter (5.7”) diamond core drilling has commenced at TLC with 10 holes planned to target 10-15 tonnes of high grade TLC lithium claystone mineralization. The 10-hole program is spread throughout the proposed PEA mine plan footprint and will provide sufficient quantity and variability of mineralized material for detailed metallurgical and pilot process plant testing later in the year.
Simon Clarke, CEO of American Lithium states, “We are extremely pleased to have filed the PEA for TLC which shows the strong economic potential of the Project utilizing best of breed conventional mining and recovery techniques. The report is based on detailed process metallurgical work with robust mining and processing operating and capital costing, which allows us to move directly into our PFS work and should enable us to fast-track that process. We have commenced large diameter drilling at TLC to collect sufficient material for our detailed metallurgical test work to be undertaken in close consultation with DRA, enabling the completion of the PFS and running of pilot operations.”
