Calgary, Alberta--(Newsfile Corp. - November 22, 2023) - LithiumBank Resources Corp. (TSXV: LBNK) (OTCQX: LBNKF) ("LithiumBank'' or the "Company") is pleased to announce results from bench-scale G2L Greenview Resources Inc. ("G2L") - Direct Lithium Extraction (DLE) test work on brine from its Boardwalk Lithium Brine Project. The Boardwalk Project is located in west-central Alberta, Canada, and situated on 100% owned crown mineral rights.

Highlights:

• Greater than 98% recovery of lithium from the Boardwalk Project brine.
• G2L DLE produced the highest purity concentrated lithium solution (eluate) of the 15 technologies tested or assessed to date.
• Greater than 90% reduction of calcium (Ca), sodium (Na), chlorine (Cl) impurities in the eluate.
• G2L DLE produced lithium eluate concentration of > 3,000 mg/L (3 g/L) Li.
• This represents:
• Greater than 40 fold increase in lithium concentration from feedstock; and
• Greater than 40 fold volume reduction of brine post DLE processing.

• Reagents used in the G2L DLE processing are approximately a third of the cost of those used in the DLE process that was used in the Company's maiden Boardwalk PEA published in May 2023. The reagents in the existing PEA accounted for 54% of the total operating costs.
• Results anticipated to be included in an updated Boardwalk PEA expected in late 2023.
• Pilot Plant testing with G2L continuous DLE (cDLE®) technology, at a rate of up to 10,000L per day to commence Q1 2024.

"The test results from G2L represent a significant improvement in the overall purity of the concentrated brine, or eluate, from the existing DLE process we employed in our existing PEA," commented LithiumBank COO Kevin Piepgrass. "We are very pleased because we can achieve this purity level using lower cost reagents that are readily available in Central Alberta. The high-grade eluate of over 3,000 mg/L lithium represents a 40-fold reduction in brine volume which significantly reduces downstream handling and processing of the brine post-DLE concentration."

"We are excited to continue optimizing our cDLE® process for the Boardwalk project brine," commented Peter Voigt, CTO of G2L. "Our focus will remain on maximizing the recovery and purity of lithium while reducing operating and capital costs. We believe further efficiencies can be achieved when we start testing our technology in the cDLE® pilot plant that is being shipped to LithiumBank this month."

LithiumBank has undertaken testing of the G2L DLE process to determine the suitability of the technology for Boardwalk lithium-rich brine. Test work produced a high-purity eluate with lithium concentrations between 3,000 - 7,000 mg/L (3-7 g/L), with low levels of impurities. Eluate concentrations of Ca, Na and Cl were reduced by 90% when compared with results used in another DLE process which was employed in the existing PEA. Furthermore, the G2L cDLE process also reduced the eluate concentrations of magnesium (Mg) and boron (B) by 38% and 57%, respectively. These results are considered very favourable as higher lithium and lower impurity concentrations in the eluate requires a smaller processing plant post-DLE and may reduce the cost of further impurity removal steps.

Brine used in the G2L test work was collected from Well 100/09-26-068-22WS/OO located in the South Sturgeon Lake oilfield, within the "Production Zone" of the Boardwalk Project and has a reported average grade of 73.8 mg/L Lithium (as previously reported in LithiumBank news release dated June 28, 2022). DLE test work was conducted in Melbourne Australia at the G2L lab facilities where the results and procedures were reviewed by Ms Lisa Parks, Qualified Person ("QP"), as defined by NI 43-101. Samples were analyzed at HRL Technology Group Pty Ltd, a third party, ISO 17025:2017certified lab, in Melbourne Australia. G2L implemented strict Quality Control and Quality Assurance (QA/QC) protocols for the analysis where each batch of analysis included duplicates, blanks, standard reference material, and check lab analysis.

In the Company's existing Boardwalk PEA published in May 2023, the costs of the reagents and resin used in the DLE accounted for 54% of the total operating expenditures ("OPEX"). Recent test work has shown that the G2L process, in addition to delivering superior eluate concentrations, can also effectively use alternative, more cost-effective reagents such as easily sourced quicklime (CaO) instead of sodium hydroxide (NaOH) and sulphuric acid (H₂SO₄) instead of hydrochloric acid (HCl). Furthermore, downstream processes are capable of recovering a significant portion of the H₂SO₄ used in the cDLE® process; this is expected to further reduce the OPEX. These reagent substitutions have shown to be effective and are expected to have a significant net positive impact on the economics in an updated PEA. LithiumBank has engaged Hatch Inc. to prepare the updated PEA in accordance with National Instrument 43-101 which the Company expects to be completed in late 2023.

LithiumBank has entered into an intellectual property license agreement dated September 8, 2023 (the "License Agreement"), as previously announced on September 11, 2023, with G2L, a subsidiary of Go2Lithium Inc., whereby G2L agreed to grant to the Company a license (the "License") in Alberta and Saskatchewan for a full suite of continuous ion exchange technologies (the "Licensed Technology"). The DLE technology will be used to extract lithium salts from enriched brines present at the Company's lithium development projects.

G2L has also agreed to provide the Company with access to a deployment-ready pilot plant that has been previously operating in Australia. Modifications to the pilot plant are almost complete and it is expected to be shipped in November to Alberta with pilot testing commencing in Q1 2024. The pilot plant is expected to have a nameplate throughput capacity of up to 10,000 L per day, making it one of the largest DLE pilot plants in North America. The Company anticipates that access to a dedicated DLE pilot plant will accelerate the Company's test work program and provide the necessary design parameters for inclusion in feasibility studies for its Boardwalk, Park Place, and Saskatchewan lithium development properties.

First Issuance of Shares Under License Agreement with G2L

The Company pleased to also announce it has issued the first 4,000,000 common shares in the capital of the Company (the "Shares") to G2L pursuant to the License Agreement.

Pursuant to the terms of the License Agreement, in consideration for the License, LithumBank has agreed to issue up to an aggregate of 14,000,000 Shares to G2L as follows:

1. 4,000,000 Shares on November 21, 2023;

2. 3,000,000 Shares upon there being an operational plant that has processed lithium brine for at least 100 hours of continuous operation in the province of Alberta (the "First Milestone");                                                                        
3. 3,000,000 Shares if the Company does not deliver a notice to G2L advising G2L that it does not intend to use the Licensed Technology for the Boardwalk Brines Project (a "Notice to Terminate") by the date that is 12 months after the achievement of the First Milestone (the "Second Milestone Deadline"), provided that the Second Milestone Deadline may be extended for an additional six months if required to generate sufficient data from piloting to support a pre-feasibility study; and

4. 4,000,000 Shares upon completion of a pre-feasibility study that concludes the Company's Boardwalk Brines Project demonstrates an ungeared internal rate of return greater than the applicable discount rate used to value the Boardwalk Brine Project,

(collectively, the "Consideration Shares").

If, following achievement of the First Milestone, a Notice to Terminate is delivered by the Company by the Second Milestone Deadline, the License shall automatically terminate and no further Consideration Shares shall be issuable.

Subject to certain exceptions, the Consideration Shares issued pursuant to the License Agreement shall not be sold or otherwise disposed of by G2L for a period of 12 months following the date of issuance of the Consideration Shares.

Mineral resources are not mineral reserves and do not have demonstrated economic viability. There is no guarantee that all or any part of the mineral resource will be converted into a mineral reserve. The estimate of mineral resources may be materially affected by geology, environment, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues. A preliminary economic assessment 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.
