Calgary, Alberta--(Newsfile Corp. - November 20, 2025) - LithiumBank Resources Corp. (TSXV: LBNK) (OTCQX: LBNKF) ("LithiumBank'' or the "Company") is pleased to announce that, further to its news release dated July 17, 2025, the Company started a comprehensive work program to unlock CAD $3.9 million in funding from the Province of Alberta through the Emissions Reduction Act ("ERA"). In partnership with the Province, LithiumBank is focused on commencing near-term production from the Boardwalk Lithium Brine Project ("Boardwalk") by employing modular Direct Lithium Extraction ("DLE") plants. This modular approach will derisk the project by reducing upfront capital while also utilizing existing oil and gas infrastructure.

To this end, LithiumBank has begun the process of acquiring a second suspended, past producing well located in close proximity to the Company's 10-6 well (acquisition announced May 16, 2024) at the 100% owned Boardwalk Project, located in west-central Alberta, Canada (Figure 1).

The Company believes this well, following exploration work, can likely support near-term lithium-brine production as it is in an area that has abundant historic production data and surface/subsurface infrastructure (wells, well pads, pipelines, roads, water, power). In order to complete the well license transfer to acquire 100% ownership of the new well, the Company requires approval by the Alberta Energy Regulator (AER). The Company will announce an update as and when additional information on this transfer of this new well license becomes available.

As previously announced (July 17, 2025), to qualify for reimbursement of expenses from the ERA, LithiumBank must complete the following milestones:

1. Complete an additional exploration drill hole through the Leduc formation reservoir at Boardwalk to support an advanced reservoir model, geological model, and collect additional brine. This exploration test well is situated so it can be converted into a production well in the future;
2. Conduct long cycle DLE testing and optimization, focusing on concentration and impurity removal testing, and conversion to lithium carbonate; and,
3. Complete a Feasibility Study at Boardwalk that assesses a low Capex, modular approach to lithium production.

The Company anticipates that this well acquisition will initiate the first milestone allowing the Company to test the reservoir productivity, collect additional brine for DLE test work, and optimize plant parameters (Milestone 2). Results from milestones 1 and 2 are expected to support a NI 43-101 Feasibility Study to be completed by the end of 2026 for the third milestone. The ERA Program will refund the Company 50% of eligible expenditures for each of the three milestones as they are completed, up to a total of $3.9M.

Over the last five years, the Company has successfully consolidated all the strategic Brine Hosted Mineral Licenses ("BHML") at Boardwalk and Park Place covering the Leduc formation (BHML areas shown in Figure 1). The NI 43-101 resource estimates at Boardwalk and Park Place, as shown below in Figure 1, are both reported as the highest-grade resource estimates in Alberta and together make LithiumBank the largest known holder of lithium brine resources in North America (Figure 1). The two projects are completely unrestricted by overlapping pore space or carbon sequestration applications/permits allowing for a clearer path toward permitting of the first production of lithium from brines in Alberta.

Notes

1: 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 ever be upgraded to a higher category. The estimate of mineral resources may be materially affected by geology, environment, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.
2: The weights are reported in metric tonnes (1,000 kg or 2,204.6 lbs).
3: Tonnage numbers are rounded to the nearest 1,000 unit.
4: In a 'confined' aquifer (as reported herein), effective porosity is an appropriate parameter to use for the resource estimate.
5: The resource estimation was completed and reported using a cut-off of 50 mg/L Li.
6: To describe the resource in terms of industry standard, a conversion factor of 5.323 is used to convert elemental Li to Li2CO3, or Lithium Carbonate Equivalent (LCE).

Equity Grant to Management

The Company has granted stock options (the "Stock Options") to two officers to purchase an aggregate of 300,000 common shares of the Company. The Stock Options will be exercisable at a price of $0.58 per share with an expiry of November 17, 2030.
