Lithiumbank’S Park Place Hydrogeological Study Reports Largest Contiguous Lithium-Rich Brine Project BY Volume IN North America

Corporate Updates

LITHIUMBANK’S PARK PLACE HYDROGEOLOGICAL STUDY

REPORTS LARGEST CONTIGUOUS LITHIUM-RICH BRINE

PROJECT BY VOLUME IN NORTH AMERICA

Calgary, Alberta. February 27, 2023 – LithiumBank Resources Corp. (TSX-V: LBNK )

(OTCQX: LBNKF) (“LithiumBank” or the “Company”) is pleased to announce the completion

of the hydrogeological study at its 100% owned Park Place Lithium Brine Project (“ PPLP”)

located 180 km west of Edmonton, Alberta, and 50 km south of the Company’s other flagship

brine project in the Boardwalk district. The hydrogeological study was completed by Matrix

Solutions Inc. (“ Matrix”) and is expected to be incorporated into an upcoming NI 43 -101

Resource Estimate.

Highlights

● PPLP hosts a combined total of 76.3 km3 (76.3 B m3) of lithium-bearing brine, 49.8 km3

within the Leduc Formation and 26.5 km3 within the Swan Hills Formation (Table 1).

● Currently the largest reported lithium -rich brine project, by volume, in North America

held by a single operator.

● Favourable average net total porosity of 11%, 12% in the north and 10% in the south

(Table 1), using a 3% porosity cut-off.

● Maximum Formation thickness: Leduc 350 metres & Swan Hills 250 metres (Figure 1).

● Thicker zones (over 200m) in the Leduc Formation are correlated with higher porosity

and are locations ideal for potential production hubs.

● The Leduc Formation and underlying Swan Hills Formation are hydraulically

connected, representing a continuous resource volume.

● Leduc Formation brine sample, collected in December 2022 from Park Place, reported

77.2 mg/L lithium (News Release Jan. 17, 2023).

The recently completed hydrogeological study indicates that PPLP hosts the largest lithium -

bearing brine, by volume, held by a single operator in North America at 76.3 km3 of brine (76.3

B m3). The entire brine is wholly contained within the 1.57 M acre Cr own mineral rights-only

land package that is endowed with modern infrastructure and abundant geological data from

decades of oil & gas activity. LithiumBank and Matrix are now using this information and recent

sampling data to produce an NI 43-101 Resource Estimate that is expected to be completed

in Q2 2023.

“We are very p roud to report the largest reported lithium brine project by volume in North

America. Beyond validating our high value asset acquisition strategy, we believe it positions

our company as one of the most attractive investments in Direct Lithium Extraction resource

development opportunities globally and at a District-Scale," commented Rob Shewchuk, CEO

of LithiumBank. “76.3 km3 is an enormous volume of lithium-rich brine with favourable porosity,

formation thickness, and lithium grades. We are confident that these metrics and grades will

lead to a positive NI 43 -101 Resource Estimate. LithiumBank will also undertake additional

brine sampling and testing of multiple Direct Lithium Extraction technologies that, together with

the Resource Estimate, will support an initial Preliminary Economic Assessment (“PEA”) at

PPLP. This assessment will compliment the Boardwalk Project PEA that is expected to be

completed shortly.”

The Leduc Formation at Pa rk Place is a confined aquifer, primarily composed of higher

porosity dolomite except for the southern portion which is primarily limestone (Figure 1). The

Swan Hills Formation consists of interbedded dolomite and limestone where both rock types,

based on core analysis, are of reservoir quality and should be considered pay intervals.

Although they are differing heterogeneous formations, the units are hydraulically connected

and could be considered as a single hydrostratigraphic unit. Both stratigraphic units dip gently

toward the southwest. The Devonian aged, Leduc Carbonate Reef complex (Woodbend

Group) and the underlying Swan Hills Formation (Beaverhill Lake Group) have historically

been known to host the highest grades of lithium-in-brine in Alberta, with samples that range

from 76 mg/L to 130 mg/L lithium within our Park Place Metallic and Industrial Mineral (MIM)

permit area. These samples are considered historic and have not been verified by a Qualified

Person (QP) under the latest NI 43 -101 Standards of Disclosure and cannot be relied upon.

Historical samples are mentioned as a reference only until such time they have been verified.

The average net total porosity is 11% (12% in the no rth and 10% in the south) using a 3%

porosity cut-off. Porosity at Park Place has been calculated differently than Boardwalk by using

a porosity cut -off rather than an average of total porosity. At Park Place , all rock and brine

within the two Formations with porosity below 3% are excluded from the volume calculations

and from the average porosity calculation , therefore resulting in a higher average net total

porosity. 11% porosity is promising, and Matrix expects that this should correspond favourably

to permeability and reservoir continuity supportive of potential future commercial production.

The hydrogeological study used 57,437 core measurements from 675 wells within the study

area from public-domain geological data from the Province of Alberta (Figure 1 & 2). 21,761

core measurements were obtained from 269 Leduc wells and 35,676 core measurements

were obtained from 407 Swan Hills wells. Matrix determined that a total of 58 drill stem tests

(DST) from 58 wells that were deemed representative. Of these D STs, 22 were within the

Leduc Formation and 36 were within the Swan Hills Formation. Matrix completed permeability

analyses on 12 DSTs for the Leduc Formation and 18 DSTs for the Swan Hills Formation.

Estimates of lithium-bearing brine volumes presented i n this disclosure are preliminary and

conceptual in nature. There has been insufficient exploration at the Park Place Lithium Brine

Project to define a mineral resource and it is uncertain if further exploration will result in

delineation of a mineral resource at PPLP.

Further Reading

The Park Place area was the focus of a study, authored by D.R. Eccles and H. Berhane,

entitled “Geological Introduction to Lithium -Rich Formation Water with Emphasis on the Fox

Creek Area of West -Central Alberta (NTS 83F and 83K)” ( https://ags.aer.ca/publication/ofr-

2011-10). The report highlights significant lithium potential in three different formations, the

Leduc (Woodbend), Nisku (Winterburn), and Swan Hills (Beaverhill Lake Group) , and is

supported by historical lithium brine samples that range from 76 mg/ L to 130 mg/L lithium in

these formations.
