LithiumBank Files NI 43-101 Resource

Estimate Technical Report for the Boardwalk

Lithium Brine Project, West-Central Alberta

Calgary, Alberta--(Newsfile Corp. - April 7, 2025) -

LithiumBank Resources Corp. (TSXV: LBNK)

(OTCQX: LBNKF)

("

LithiumBank

" or the "

Company

") is pleased to announce the filing of a technical

report (the "

Report

") for an updated mineral resource estimate at its 100% owned Boardwalk lithium

brine project ("

Boardwalk

") located in west-central Alberta. The Report is entitled "LithiumBank

Resources Corp. Boardwalk NI 43-101 Technical Report" with an effective date of February 20, 2025.

The Boardwalk resource estimate highlights were originally announced by the Company on

February 20,

2025

. The Report can be found on the Company's website and on

SEDAR+

.

Boardwalk Resource Estimate Highlights:

Boardwalk hosts the highest-grade lithium brine measured or indicated current resource estimate

in Alberta at 81.6 mg/L lithium.

5,195,000 tonnes of measured or indicated of lithium carbonate equivalent ("

LCE

") within the

Leduc Formation ("

Fm

") aquifer at an average of 81.6 mg/L lithium (Table 2).

2,777,000 tonnes of inferred LCE within the Leduc Fm and Beaverhill Lake Group ("

Gp

")/Swan

Hills Fm aquifers, which directly underlies the Leduc Fm, at a weighted average of 79.0 mg/L

lithium (Table 1).

The resource estimate at Boardwalk increased by over 30% due to an increase in the lithium

grade via recent "10-06" drilling/testing program (Figure 1), additional measurements, refined

parameterization of Leduc Fm aquifer geometry and effective porosity, as well as confirming the

presence of lithium in the Beaverhill Lake Gp/Swan Hills Fm aquifer (Figure 3).

The subsurface reservoir model will assist in planning well networks and locations in future

economic and engineering studies.

The Report estimates the LCE measured resource at 1,671,000 tonnes at a grade of 81.2 mg/L lithium

and 3,524,000 tonnes of indicated LCE at a grade of 81.8 mg/L lithium within the Leduc Fm. This leads

to a combined total of measured and indicated resources of 5,195,000 tonnes LCE with an average

grade of 81.6 mg/L lithium (Table 2). Additionally, recent work estimates the inferred LCE resources of

1,128,000 tonnes at 81.8 mg/L lithium and 1,649,000 tonnes inferred LCE at 78.1 mg/L lithium within the

Leduc and Beaverhill Lake Gp/Swan Hills Fm (Table 1), respectively. The data and workflow process

were reviewed and validated by Alex Haluszka of Montrose Environmental Solutions Canada Inc.; a

Qualified Person as defined by National Instrument 43-101 -

Standards of Disclosure for Mineral

Projects

("

NI 43-101

").

The Boardwalk resource estimate is an increase in lithium grade of approximately 18% from the

previous resource estimate and an increase in overall lithium resources by approximately 30% (previous

Boardwalk resource estimate with effective date Feb. 22, 2024) and increasing the Company's overall

lithium resources as shown in Table 2 and Figure 3.

Note 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.

Note 2: The weights are reported in metric tonnes (1,000 kg or 2,204.6 lbs).

Note 3: Tonnage numbers are rounded to the nearest 1,000 unit.

Note 4: In a 'confined' aquifer (as reported herein), effective porosity is an appropriate parameter to use for the resource estimate.

Note 5: The resource estimation was completed and reported using a cut-off of 50 mg/L Li.

Note 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).

*The NI 43-101 compliant Park Place resource estimate entitled "LithiumBank Resources Corp. Park Place NI 43-101 Technical Report" effectively dated

June 24, 2024, is available on SEDAR+

**LithiumBank is following the same systematic development strategy at Park Place as it has with Boardwalk.

Boardwalk consists of 395,369 acres of contiguous Brine Hosted Mineral Licenses ("

BHML

") owned

100% by LithiumBank. The Company has consolidated 100% of BHML's overlying the Leduc Fm and

Beaverhill Lake Gp/Swan Hills Fm at Boardwalk with no freehold mineral rights or any carbon

sequestration/pore space permits or applications existing over Boardwalk. Boardwalk is situated

approximately 85 km east of Grande Prairie and approximately 270 km northwest of Edmonton.

Boardwalk is also approximately 50 km to the north of the Company's Park Place lithium brine project

("

Park Place

"). Boardwalk and the surrounding area have seen over 70 years of hydrocarbon extraction

resulting in a well-established and well-trained labour force, networks of all-weather gravel roads, drill

sites that can be easily accessed from Provincial highways, and electrical transmission lines that run

through the project (see Figure 1).

Mineral Resource Quality Assurance and Quality Control

Samples collected in 2021 and used in the resource estimate were analysed at AGAT Laboratories, an

ISO 17025:2017 certified lab, in Calgary Alberta ("

AGAT

"). LithiumBank implemented strict Quality

Control and Quality Assurance ("

QA/QC

") protocols for the analysis (as per the news release

June 28,

2022

) . Initial testing of the four wells included six brine samples from each well. Well number 100/09-26-

068-22W5/00 was sampled first and included six lab duplicates, blanks, standard reference material,

and check lab analysis.

LithiumBank conducted a second round of QA/QC with a new standard reference material sample made

to mimic the Sturgeon Lake brine grades. The second round also included blanks and duplicates and

consisted of an additional 13 samples from well 100/09-26-068-22W5/00 and one additional sample

from the other three wells. All samples were analysed at AGAT Labs in Calgary, AB.

LithiumBank later acquired well 100/10-06-069-21W5/00 ("

10-6

") which was extended, via a sidetrack,

from the top of the Leduc Fm to the bottom of the Beaverhill Lake Gp/Swan Hills Fm (as per the news

release

September 23, 2024

). The sampling at the 10-6 was done under the supervision and guidance

of Gord McMillan, P. Geo., who was on site at the 10-6 during the sampling campaign to ensure QA/QC.

Brine samples were sent to AGAT. Duplicate samples were sent to Isobrine Laboratory and Bureau

Veritas Laboratory in Edmonton Alberta as duplicate check lab samples. Each batch of samples

included duplicate samples and standard reference material to ensure QA/QC.

The scientific and technical information relating to the mineral resource estimate presented in this news

release has been reviewed and approved by Alex Haluszka P. Geo. of Montrose Environmental

Solutions Canada Inc., Alex Haluszka is independent of LithiumBank and a Qualified Person as defined

by NI 43-101.

The Report was prepared by the following Qualified Persons; Alex Haluszka P. Geo. of Montrose

Environmental Solutions Canada Inc., George C Brindle, P.Eng., of Skoki Energy Advisors Inc., Kevin

Piepgrass, P.Geo. The updated resource estimate was prepared in collaboration with global technology

and services company SLB.

Risks and Uncertainties

There is no guarantee that a company can successfully extract lithium in a commercial capacity. Initial

mineral processing bench-scale and/or demonstration pilot test work may not translate to a full-scale

commercial operation.
