Star Metro - Independent Analysis Supports Hydraulic Borehole Mining Method Applicability for Bonnie Claire Lithium Project

Nevada Lithium's CEO, Stephen Rentschler, comments:

Highlights of Independent Analysis

• Alternative mining methods identified: High-level evaluation identified block caving and sub-level caving as alternative mining methods for assessment in trade-off studies within the overall PFS process. Alternative mining methods may require additional testing, including drilling, to confirm the deposit's amenability to these mining methods

Technical Due Diligence

The Company retained WSP to undertake a high-level desktop review to evaluate the suitability of the HBHM method which was identified as the preferred mining method in the Company's 2025 ("PEA").

The due diligence included a review of the available geotechnical information on the deposit to help evaluate HBHM in this environment, and a review of the process and pumping modelling incorporated into the PEA study. WSP used benchmarking against existing borehole recovery operations in northern Saskatchewan to assess the validity of the assumptions regarding the amenability of HBHM on the Bonnie Claire deposit for mining and process methodologies.

The technical review undertaken by WSP also included a high-level evaluation of alternative mining methods to evaluate amenability to these mining methods at the Bonnie Claire deposit.

Summary and Recommendations

WSP believes that hydraulic borehole mining is applicable to the Bonnie Claire deposit and is a potentially viable method for recovery of the deeper mineralized zones at the Bonnie Claire site. This assessment is subject to the successful completion of additional bench-scale testing and modelling. WSP recommends that the following work be undertaken going into the PFS:

Following the recommendations above, going into the FS, WSP recommends HBHM pilot testing and field validation. This pilot test would involve the mining of a representative section of the Lower Claystone (including 2,000-2,500 ft interval) to determine the effectiveness and design parameters of the HBHM method. Jetting efficiency, slurry consistency, particle size distribution, and pumping performance would also be evaluated.

¹Results of Recent PEA.

The Company recently filed a PEA on the Bonnie Claire Lithium Project. The PEA has an effective date of March 31, 2025 and presents a $6.829 billion after-tax Net Present Value ("NPV") at an 8% discount rate, based on $24,000/tonne Li₂CO₃, $950/tonne boric acid, together with a 32.3% after-tax Internal Rate of Return ("IRR"). Results of the PEA were announced in the Company's news release, dated August 6, 2025. The PEA is preliminary in nature and includes Inferred Mineral Resources that are too speculative geologically to be classified as Mineral Reserves. There is no certainty that the results of the PEA will be realized.

Cautionary Note Regarding Forward-Looking Statements

This news release contains forward-looking statements and forward-looking information (collectively, "forward-looking statements") within the meaning of applicable Canadian securities legislation. These statements relate to matters that identify future events or future performance. Often, but not always, forward looking information can be identified by words such as "could", "pro forma", "plans", "expects", "may", "will", "should", "budget", "scheduled", "estimates", "forecasts", "intends", "anticipates", "believes", "potential" or variations of such words including negative variations thereof, and phrases that refer to certain actions, events or results that may, could, would, might or will occur or be taken or achieved.

The forward-looking statements contained herein include, but are not limited to, statements regarding: the performance of the Project and the results and assumptions of the PEA, including projected economics, production rates, mine life, capital costs, operating costs, internal rate of return, net present value, payback period, sensitivity analyses, and the potential for optimization of project economics and value enhancement opportunities; potential to recover rare earth elements as a by-product of the Project; the potential development of the Project, including future permitting, feasibility studies, and development activities; mineral resource estimates, the potential to convert inferred mineral resources to indicated or measured mineral resources, and future exploration activities with the potential to expand mineral resources; mining methods, production targets, and processing strategies; the impact of new tax provisions and regulatory changes; market conditions and commodity prices for lithium carbonate and boric acid, including sustained lithium demand and prices; and the Company's ability to finance the development of the Project.

Making the forward looking statements in this news release, Nevada Lithium has applied several material assumptions, including without limitation: basis, qualifications, and assumptions made by the qualified person, sustained market fundamentals resulting in continued lithium and boron demand and favorable commodity price assumptions for lithium carbonate and boric acid; the receipt of any necessary permits, licenses and regulatory approvals in connection with the future development of Bonnie Claire in a timely manner and Nevada Lithium's ability to comply with all applicable regulations and laws, including environmental, health and safety laws, supported by political and regulatory stability in Nevada, USA; the availability of financing on suitable terms for the development, construction and continued operation of Bonnie Claire; the Project containing mineral resources and the accuracy of the Mineral Resource Estimate; the reliability of the PEA and its underlying assumptions; the successful application of the HBHM method; metallurgical recovery rates of 85% for lithium and 48% for boron; and capital and operating cost estimates.
