    Calgary, Alberta, Canada, May 24, 2023 – Volt Lithium Corp. (TSX-V: VLT, OTCQB: VLTLF, FSE:
    I2D) (“Volt” or the “Company”) is very pleased to announce the results from a successful pilot
    project to test its proprietary direct lithium extraction (“DLE”) technology in a simulated commercial
    environment (the “Pilot Project”). The Pilot Project proved the Company’s ability to achieve
    lithium recoveries of 90% based on concentrations of only 34 mg/L. The Company also simulated
    operating conditions at concentrations of 120mg/L and achieved recoveries of up to 97% with
    operating costs under CAD$4,000 per tonne, assuming sustained average annual production of
    20,000 tonnes (tpa) of lithium hydroxide monohydrate (“LHM”). Further, in an unprecedented
    result, the Pilot Project proved Volt’s DLE technology can maintain 90% lithium recoveries in
    concentrations as low as 34 mg/L, and still maintain commercial economics, an achievement that
    has yet to be reported by other lithium producers.
    “Volt has achieved remarkable and ground-breaking results through the Pilot Project, and
    achieved an impressive 97% recovery rate with 120 mg/L concentrations under simulated
    operating conditions. I want to thank the entire R&D, operational and engineering teams for their
    dedication and hard work in successfully executing this first phase,” commented Alex Wylie,
    President and CEO of Volt. “These results confirm that Volt’s proprietary technology is a true
    game-changer. With this accomplishment, we are poised to lead the way in North America as the
    first commercial producer of lithium from oilfield brines, which we are targeting for the second half
    of next year.”
    Volt is pleased to be participating in a webinar hosted by Energy Prospectus Group later this
    morning, Wednesday, May 24 at 11AM ET (9AM MT / 8AM PT) to discuss the Company, the
    significance of these results and what lies ahead for Volt and its stakeholders. All interested
    parties are encouraged to join the live webinar by clicking HERE.
    In March of 2023, Volt commenced its Pilot Project which was designed to simulate a commercial
    operating environment and allow the Company to confirm economic recoveries of lithium at
    concentrations of up to 120 mg/L, an equivalent concentration to that found in the Muskeg aquifer
    at Volt’s Rainbow Lake Property as outlined in the Company’s press release issued May 18, 2023.
    The Pilot Project enables Volt to verify the extraction capabilities of its IES-300 technology and to
    determine operating costs for the DLE process, a key factor in determining viability for commercial
    applications and ultimate profitability.
    The Company consistently achieved extraction recoveries up to 90% using IES-300 at low lithium
    concentrations of 34 mg/L. Volt simulated pilot conditions using brine concentrated to 120 mg/L
    and achieved lithium extraction results as high as 97% with realized operating costs of less than
    CAD$4,000 per tonne, assuming sustained average production of 20,000 tpa of LHM. The
    Company intends to process brines with lithium concentrations of 120 mg/L through the Pilot
    Project in the next week to validate in practice the results Volt realized in its simulated
    As outlined in the Company’s technical report, Volt has a total inferred mineral resource of 4.3
    million tonnes of lithium carbonate equivalent (“LCE”) (4.9 million tonnes of LHM) at its Rainbow
    Lake property, more than 215 times its targeted sustained average production of 20,000 tpa, with
    lithium concentrations as high as 121 mg/L. This affords Volt ample brine sources at varying
    lithium concentrations in its current asset base to continue advancing commercial development,
    including commencing discussions to secure the required refining infrastructure needed to
    generate commercial quantities of LHM.
    Volt’s R&D and operational team, led by Dr. John McEwen, PhD, Chem, believe the operating
    conditions have been successfully achieved for lithium extraction culminating in a successful Pilot
    Volt’s proprietary DLE technology involves a two-stage process to extract lithium from oilfield
    brine. In Stage One, the oilfield brine is treated using proven equipment and established
    processes, and during the Pilot Project, Volt confirmed the ability to effectively remove up to 99%
    of contaminants in the preparation of clean brine for the DLE process. This is critical as having
    contaminants in the brine causes interference during the DLE process and can lead to
    uneconomic processes.
    In Stage Two, Volt uses the Company’s proprietary IES-300 technology to extract lithium from the
    brine, which is concentrated down into a lithium chloride solution that will ultimately be upgraded
    to LHM, an essential raw material required for batteries, and in particular, electric vehicle
    batteries. Volt’s IES-300 technology reduces the amount of re-agent required to treat oilfield brine
    as it enters the extraction process.
    The combination of continued high lithium extraction levels, a streamlined process and ongoing
    efficiency improvements has resulted in lower operating costs for Volt, demonstrated at less than
    CAD$4,000 per tonne in the Pilot Project, driving robust economics that can support sustainability
    and anticipated profitability over the long-term.
    While the Company’s asset base offers significant development opportunities at the higher lithium
    concentration levels, Volt recognized that expanding its asset base and access to brine
    necessitates achieving extraction recovery levels of at least 90% using brine that contains much
    lower lithium concentrations.
    Through the Pilot Project, the Company
    simulated a number of operating conditions
    and various cycle times for its proprietary IES300 technology in order to determine the
    parameters for eventual commercial
    operations and confirm IES-300 was robust
    enough to successfully extract lithium from the
    lowest concentration brine in oilfields and other
    reservoirs. Volt succeeded in achieving
    recoveries of 90% at concentrations as low as
    34 mg/L, with the operating costs associated
    with varying concentration levels under
    commercial operating assumptions shown in
    Figure A. This technological discovery
    effectively opens up multiple oilfield reservoirs across North America that can now offer
    commercial lithium extraction using Volt’s proprietary DLE process.
    The operating cost estimates presented in Figure A included reagent, direct and indirect costs for
    the DLE process, with approximately 63% of the total operating costs based on usage of reagent
    and other consumables that are required to extract lithium from the brine, as well as conversion
    to LHM. Since the Company did not seek to optimize reagent usage during the Pilot Project, Volt
    anticipates that future reagent consumption can be optimized and will be explored once a
    permanent pilot plant is commissioned.
    Based upon the successful execution of the Pilot Project, Volt will look to establish a permanent
    pilot plant in order to continue refining its IES-300 technology, test the optimization of reagent
    usage, and continue to improve operating conditions with the goal of continually driving down
    operating costs to achieve improved economics that underpin commencing commercial

    In addition, Volt will continue to focus on upgrading its resource estimate and commencing the
    preparation of a Preliminary Economic Assessment based on the successful extraction and
    operating results of this Pilot Project and the Company’s recently published NI 43-101 resource
    report. Volt will also advance the engineering design phase to determine the optimal commercial
    parameters for its DLE process which will ultimately support the achievement of commercial
    production by the second half of 2024.
