CEO.CA Chairman's Briefing

Calgary, Alberta--(Newsfile Corp. - September 23, 2024) - LithiumBank Resources Corp. (TSXV: LBNK) (OTCQX: LBNKF) ("LithiumBank'' or the "Company") is pleased to announce lithium assay results from brine samples taken below the hydrocarbon zone during drilling at the Company's 100%-owned Boardwalk lithium Brine Project ("Boardwalk"). Assays from the Company's licensed well, 100/10-06-069-21W5/00 ("10-6") ranged between 79.8 - 84.4 mg/L lithium, averaging 82 mg/L lithium (Table 1) over a 167m vertical interval (2,588 to 2,761m) (Figure 1) in from the Leduc formation ("Fm") in a 48 hour constant rate flow test. The first ever sampling from the Swan Hills formation in the Boardwalk area ranged between 76.3 - 79.9 mg/L lithium, averaging 78 mg/L lithium over an 84m vertical interval (2,761 - 2,829m) (Figure 1) in an isolated swab test. These results will be included in a future updated mineral resource estimate for the Boardwalk Project.

"We are very pleased to report that the grades from drilling the Leduc and Swan Hills Fm's at Boardwalk are very similar to those of the Park Place Lithium brine project 50 kms to the south east at 82 and 78 mg/L lithium, respectively," commented Rob Shewchuk, CEO of LithiumBank. "The lithium assay results collected from below the hydrocarbon zone in the Leduc Fm are approximately 15% better than samples collected from the hydrocarbon zone in the Leduc Fm. We look forward to seeing the impact that the increased lithium grade and the addition of the Swan Hills Fm results will have on an updated resource estimate for the Boardwalk project. With large bulk samples collected from the 10-6 at 82 mg/L lithium, we also expect to see a positive impact on results from Direct Lithium Extraction ("DLE") pilot testing of this brine given the better head grade."

The 10-6 well drilling program, completed August 8^th, 2024, located in the indicated resource area of Boardwalk (Figure 2) drilled through the entire 316m of the Leduc and Swan Hills Fm. The sampling program included a constant rate flow test in the Leduc Fm starting below the hydrocarbon zone from 2,588 - 2,761m in depth (167m) (Figure 1) over a 48 hour period. During the constant flow rate test, brine samples were collected at approximately 4 hour intervals for the purposes of chemical analysis to determine a representative grade of the entire 167m Leduc Fm interval, which are shown in Table 1. The constant rate flow test also collected additional reservoir data to assist in improving the confidence in the subsurface geology as well as collect a bulk brine sample (248 cubic metres) for DLE pilot testing at the Company's DLE facility in Calgary, AB. Brine samples at the 24 hour mark and beyond of the constant rate flow test were found to be representative of the Leduc Fm and are reported in Table 1.

The Swan Hills lithium brine samples are the first ever taken within the Boardwalk project area. The Swan Hills Fm lies directly below the Leduc Fm and assays returned lithium grades between 76.3 - 79.9 mg/L lithium, averaging 78 mg/L lithium from isolated zone swab testing over the 84m Fm thickness (2,761 - 2,829m) (Figure 1). The swab test uses plugs above and below an interval to isolate a zone and collect brine from that interval and was performed over a period of 9 hours. Until now, there has been no historical lithium brine sampling information in the Swan Hills Fm in the Boardwalk area.

The sampling was done under the guidance of Gord McMillan, P. Geol., who was on site at the 10-6 during the sampling campaign to ensure Quality Assurance and Quality Control ("QA/QC"). Brine samples were sent to AGAT Laboratory in Calgary Alberta. 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 drilling program of the 10-6 well commenced on July 26^th, 2024 and was completed August 8^th, 2024. The Alberta Energy Regulator (AER) approved the transfer of 100% ownership of the 10-6, along with surface rights and road access from the previous owner/operator to LithiumBank on May 16th, 2024. The well is in the eastern portion of Boardwalk's 'Production Zone' as described in the Company's January 2024 Preliminary Economic Assessment ("PEA") as shown in Figure 1.
