LithiumBank Resources Corp. (TSXV: LBNK) (OTCQX: LBNKF) ("LithiumBank'' or the "Company") is pleased to provide an update and near term work plans for its 100%-owned Boardwalk and Park Place Lithium Brine Projects located in west-central Alberta, its Kindersley and South Projects located in Saskatchewan, as well as the Company's exclusively licensed Direct Lithium Extraction ("DLE") technology and pilot plant in Calgary, Alberta.

LithiumBank continues to advance the Company's portfolio of brine projects through geological interpretation, subsurface modelling, resource development, and advanced engineering. This work includes the installation and commissioning of its 10,000 L/day DLE pilot plant as well as testing brines from the Company's projects using its exclusive licensed DLE technology. All of these parallel work streams will be funded by the net proceeds of the Company's recent, non-dilutive sale of its Estevan project in Saskatchewan for CAD $15M.

LithiumBank CEO, Rob Shewchuk, commented, "I am very pleased with the progress the company is making on all fronts. The $15M sale of Estevan on March 31 proves that our model of early acquisition and efficient development creates outsized returns for the company. Furthermore, the funds from this first asset sale have the potential to accelerate significant value creation across our large Western Canadian portfolio of brine projects. The non-dilutive capital will also preserve our share capital structure with over 40% ownership by insiders, consultants and employees."

Brine Testing and DLE Pilot Plant Update

Over the next several months, LithiumBank will be running DLE pilot campaigns with brine collected from its Boardwalk, Park Place, and Saskatchewan projects. The Pilot Plant is currently being permitted by the City of Calgary and is expected to be fully commissioned in Q2 of this year. The pilot plant is a scaled version of the exclusive licensed DLE technology from G2L Greenview Resources Ltd. ("G2L") (September 11, 2023) and has a 10,000 L/day brine throughput capacity, which is one of the largest lithium brine processing pilot plants in North America (Figure 1).

The indoor DLE pilot facility is designed with safety and efficiency as the first priority. The plant replicates field operating conditions with a pre-treatment process and a heater to flow the brine into the DLE process at ~70 degrees celsius. Initially, a series of 3-10 day metallurgical tests will be run to determine lithium recovery rates and impurity removal with the use of low cost reagents. Following these tests, the Company will focus pilot test work on optimising reagent consumption, sorbent residence time, to efficiently maintain high lithium recovery at high flow rates. Results from this work will form the basis of Feasibility level studies and potentially future commercial operations.

Boardwalk Sampling

At Boardwalk, LithiumBank is assuming title of a well that previously produced oil and gas from the top of the Leduc Formation ("Fm"). The Company plans to extend the well, located within the production zone contemplated in the Company's January 2024 PEA (Figure 2) to the bottom of the Leduc Fm to allow for the collection of a range of reservoir and brine chemistry data throughout the entire estimated 200 m thickness of the Leduc aquifer in that location. These results as well as additional advanced subsurface modelling data will be used to update and upgrade the current Mineral Resource Estimate, effectively dated February 22, 2024, of 395,000 t LCE Indicated at 71.6 mg/L Li and 5,734,000 t LCE Inferred at 68.0 mg/L Li at Boardwalk. The indicated and inferred Boardwalk Leduc Formation lithium-brine resource estimations are presented as a total (or global value), and were estimated using the following relation in consideration of the Leduc Formation aquifer brine:

Lithium Resource = Total Brine Aquifer Volume X Average Porosity X Percentage of Brine in the Pore Space X Average Concentration of Lithium in the Brine.

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.

Park Place Resources Estimate

At Park Place, the Company continues to work with SLB Ltd. ("SLB", formerly Schlumberger) to deliver an initial mineral resource estimate by May 2024. The Park Place project consists of 1.4 million contiguous acres of Brine Hosted Mineral Licences ("BHML") that strategically overlays both the lithium-bearing Leduc and Swan Hills Formations (Figure 2). Initial brine sampling in January 2023 from the Leduc Formation averaged 77.2 mg/L lithium (January 17, 2023). Three brine samples were collected from well 100/12-03-059-23W5/00 and returned grades ranging between 71.2 - 82.0 mg/L lithium with an overall average of 77.2 mg/L lithium. Samples were analysed at AGAT Laboratories, an ISO 17025:2017 certified lab, in Calgary, Alberta. LithiumBank implemented strict Quality Control and Quality Assurance (QA/QC) protocols for the analysis. Testing of the three samples included three duplicates, two blanks and one standard reference material. Samples were collected from the well head by BV Labs technicians and couriered to AGAT Laboratories for analysis in Calgary. LithiumBank recently acquired both 2D and 3D subsurface seismic data and are utilizing hundreds of oil and gas wells to assist SLB in the reservoir modelling.

2024 Sample Collection Program

LithiumBank plans to execute additional sampling campaigns in 2024 for the collection of bulk brine samples across the districts of Boardwalk, Park Place, and Saskatchewan for processing in the Pilot Plant. The Company continues to work closely with petroleum producers to source brine from existing wells which minimises environmental impacts and financial impacts. Chemical analysis of brine from the Company's two Alberta projects indicates their strong similarity and probable compatibility with the exclusively licensed G2L DLE technology.
