LithiumBank Files NI 43-101 Resource Estimate Technical Report for the Park Place Lithium Brine Project, West-Central Alberta

Calgary, Alberta--(Newsfile Corp. - August 7, 2024) - LithiumBank Resources Corp. (TSXV: LBNK) (OTCQX: LBNKF) ("LithiumBank" or the "Company") is pleased to announce the filing of the National Instrument ("NI") 43-101 Technical Report for the Park Place Lithium-Brine Project located in West- Central Alberta, Canada (Figure 1) entitled "LithiumBank Resources Corp. Park Place NI 43-101 Technical Report" effectively dated June 24, 2024. The Park Place resource estimate highlights was originally announced by the Company on June 24, 2024. The Park Place Technical Report can be found on the Company's website and on SEDAR+.

Park Place Resource Estimate Highlights include:

• Park Place is the largest known NI 43-101 inferred lithium brine resource estimate in North America.

• Highest known reported lithium-in-brine grades used in a NI 43-101 inferred lithium resource estimate in Alberta.

• 10,076,000 tonnes inferred LCE within the Leduc Fm aquifer at an average of 79.4 mg/L lithium.

• 11,620,000 tonnes inferred LCE within the Swan Hills Fm aquifer, which underlies the Leduc Formation, at an average of 80.9 mg/L lithium.

• Multiple high porosity areas occur that have a combined Leduc & Swan Hills Fm thickness of over 350 metres, and as high as 511 m, to be studied for potential selection of future PEA.

• Subsurface reservoir modelling conducted by SLB and Matrix included data from 420 wells, 104 km2 of 3D seismic data and 262 km of two-dimensional seismic data.

• The subsurface reservoir model will assist in planning well networks and locations in future economic and engineering studies such as a PEA; and

• Park Place bulk brine sample collection to occur in H2 2024 to be included in the 10,000 L/day direct lithium extraction ("DLE") pilot plant test work located in the Company's DLE facility in Calgary, Alberta.

1. Total volume of rock and pore space
2. Total volume of effective porosity
3. Calculated using a weighted average (by pore volume) from the average grade of the Leduc and Swan Hills formations
4. Calculated using a weighted average porosity by total formation volume for both Leduc and Swan Hills formations

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 consolidated Park Place project consists of 1,404,558 acres of contiguous Brine Hosted Mineral Licenses ("BHML"). The project is situated between Edson, Fox Creek, and Hinton, approximately 180 km west of Edmonton, and is approximately 50 km to the south of the Company's Boardwalk lithium brine project ("Boardwalk"). This area has 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 and adjacent to the project (see Figure 1).

The mineral resource estimate work was prepared within a portion of the Park Place Property (81%) that is defined as the area of interest and totals 1,140,115 acres (Figure 1). The Swan Hills Fm directly underlies the Leduc Fm and appear to be in hydraulic communication based on regionally available pressure data. While they may represent a regionally connected aquifer system, the two formations are evaluated separately due to an identifiable difference in lithology and porosity. The Swan Hills Fm is mapped to from 24 to 264 m in thickness within the claims area and the Leduc Fm immediately overlies the Swan Hills Fm, where present, with a maximum thickness of 366 m within the claims area. The maximum observed combined thickness where the two units overlap within the property is 511 m of highly porous reservoir rock occur that would potentially present ideal locations for consideration within a PEA.
