LithiumBank Files Preliminary Economic Assessment Technical Report for the Boardwalk Lithium Brine Project, West-Central Alberta

CALGARY, June 21, 2023 - LithiumBank Resources Corp. (TSX-V: LBNK) (OTCQX: LBNKF) ("LithiumBank" or the "Company") is pleased to announce the filing of the Boardwalk Lithium Brine Project Preliminary Economic Assessment ("PEA") Technical report entitled "Preliminary Economic Assessment (PEA) for LithiumBank Resources Boardwalk Lithium-Brine Project in West- Central Alberta, Canada" effectively dated June 16, 2023, originally announced May 25th, 2023.

PEA Highlights

• 31,350 metric tonnes per year of battery grade lithium hydroxide monohydrate ("LHM")¹ production over a 20-year period, the largest proposed LHM production in North America;
• USD $2.7 Billion NPV₈ and 21.6% IRR on a pre-tax basis;
• USD $1.7 Billion NPV₈ and 17.8% IRR on an after-tax basis;
• OPEX of USD $6,807/ton LHM;
• Direct Lithium Extraction ("DLE") used to process Boardwalk brine will require less fresh water and have a surface footprint that is a fraction of hard rock or evaporation lithium production;
• Ramp up to commercial production within 3 years is possible under newly established permitting directives;
• Located in Tier 1 jurisdiction, west-central Alberta, which has a long history of resource extraction, well established infrastructure, and an actively supportive government;
• Power to be generated on site using high-efficiency gas turbines with steam cogeneration that will lower the project's overall carbon footprint. The proposed gas turbine units may be run on 80% hydrogen when a reliable supply is available;
• Multiple opportunities to enhance project economics through optimization, further engineering, and pending incentive tax credit;
• Project economics used USD $26,000/t LHM and provides strong leverage to higher lithium prices.

A PEA is preliminary in nature as it includes a portion of inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves, and there is no certainty that the preliminary economic assessment will be realized.

In addition to the Boardwalk project, LithiumBank also holds two other development ready, district scale assets in Western Canada, Park Place (AB) & Saskatchewan. The Company sees multiple avenues to create value in the coming months through enhancing the economics of the Boardwalk PEA, delivering an initial PEA for Park Place (AB), and by estimating a resource at its Saskatchewan assets.

"The Boardwalk PEA sets the stage for our team to pursue advanced lithium resource development in Western Canada" commented Rob Shewchuk CEO & Director of LithiumBank. "By the end of 2023, we expect to commence pilot plant studies in parallel on both Boardwalk and Park Place and capture near-term enhancement opportunities that have already been identified. We believe this has the potential to position both the Boardwalk and Park Place districts among the most attractive direct brine projects in North America."

Near Term PEA Enhancements

• The Government of Canada announced an Investment Tax Credit (ITC) for Clean Technology Manufacturing in its Budget 2023. Refundable tax credit will be applied on capital expenditures for the extraction and processing of critical minerals (ITC link);
• Use of smaller electrical submersible pumps (ESPs) that could fit in reduced diameter well casing throughout the network that is expected to reduce capital expenditures;
• Leveraging of existing wells and surface infrastructure including roads, well pads, pipelines, and utilities;
• Reduction of well and power requirements through enhanced 3-D reservoir modelling and new drilling information;
• Next generation sorbent being developed by Conductive, the provider of the lithium brine DLE technology chosen for the PEA, is expected to reduce costs, increase efficiency and reduce reagent consumption;
• Alternative DLE technology trade-off studies;
• Utilise ZS2 Technologies Inc. to capture and sequester CO₂ emissions to produce carbon credits, extract magnesium from barren brine to produce low carbon cement products that will lower brine reinjection amounts by at least 10%; and
• Additional trade-off studies aimed at streamlining pipeline infrastructure.

Cautionary Statement Regarding Forward Looking Statements

This release includes certain statements and information that may constitute forward-looking information within the meaning of applicable Canadian securities laws. All statements in this news release, other than statements of historical facts, including statements regarding future estimates, plans, objectives, timing, assumptions or expectations of future performance, including without limitation, the results of the Preliminary Economic Assessment, including the expected NPV of the Boardwalk project; expectations that commercial production will be achievable within 3 years under new permitting directives; expectations that governmental regulators will be supportive of the Boardwalk project; expectations that the carbon footprint of the Boardwalk project will be reduced through DLE extraction technology and through the use of high-efficiency gas turbines with steam cogeneration; expectations that that the 30% Investment Tax Credit (ITC) for Clean Technology Manufacturing will be passed by the Government of Canada; expectations that reduced capital expenditures can be achieved on the Boardwalk projects; expectations that the Boardwalk project will see reduced costs, increased efficiency and reduced reagent consumption through the use of new sorbent; expectations that the Company will pursue and obtain a mineral resource estimate at its Saskatchewan asset and/or a Preliminary Economic Analysis on the Park Place project on the timing anticipated or at all; and expectations that the Company will commence pilot plant studies on both the Boardwalk and Park Place projects by the end of 2023 are forward-looking statements and contain forward-looking information. Generally, forward-looking statements and information can be identified by the use of forward-looking terminology such as "intends" or "anticipates", or variations of such words and phrases or statements that certain actions, events or results "may", "could", "should" or "would" or occur.
