On July 21, 2022, the Company exercised the option to purchase the rights to unpatented lode claims in Tonopah, Nevada. Since that time, the Company has worked with third parties to conduct drill programs and analysis to verify the grade and continuity of the mining claims. Over 50% of the inferred mineral resources have been upgraded to measured and indicated classifications. The Company is still in the exploration stage and expenses all mineral exploration costs. If the Company identifies proven and probable reserves and develops an economic plan for operating a mine, it will enter the development stage and capitalize future costs until production is established.

On July 22, 2023, the Company began a third exploration program to advance its Tonopah Flats Lithium Project. This drill program includes core infill and step out drilling to support the evolution of its domestic resource with the goal of upgrading to a ‘measured and indicated’ resource classification. The Company selected and engaged KB Drilling for the collection of infill and step out samples for this latest drill program, which consists of sample collections from eight additional drill holes and includes 6,500 feet of total drilling.

In December 2023, the Company entered into a vacant land offer and acceptance agreement for the Company’s acquisition of certain mineral patents totaling $0.2 million which was capitalized to mining properties.

On April 24, 2024, the Company announced the completion of the “Amended Resource Estimate and Initial Assessment with Project Economics for the Tonopah Flats Lithium Project, Esmeralda and Nye Counties, Nevada, USA” (“Amended IA”) and the publication of the S-K 1300 Technical Report Summary (“TRS”) disclosing mineral resources, including an initial economic assessment, for the Tonopah Flats Lithium Project. The TRS was completed by RESPEC Company LLC, a qualified person, in compliance with Item 1300 of Regulation S-K and with an effective date of April 5, 2024.
