Calgary, Alberta--(Newsfile Corp. - September 4, 2024) - LithiumBank Resources Corp. (TSXV: LBNK) (OTCQX: LBNKF) ("LithiumBank'' or the "Company") is pleased to announce the completion of an initial bulk brine sampling program at Park Place located in west-central Alberta, Canada. The bulk brine sampling program successfully collected 148 cubic meters (m³) of lithium-rich brine from an active gas producing well within the upper 72 m interval of the Leduc Formation from the vertical well 100/12-03-059-23W5/00 (Figure 1). Analysis of the brine samples taken across the 72 m interval ranged from 75.0 - 90.9 mg/L lithium with an average of 83.8 mg/L lithium (Table 1). This is within the range of samples collected and first reported on January 17, 2023.

"LithiumBank continues to achieve critical milestones of the Company's development roadmap that further add value and de-risk the Park Place Project," commented Rob Shewchuk, CEO of LithiumBank. "The bulk brine sample, collected within North America's largest NI 43-101 inferred lithium brine resource, will be processed through the 10,000 l/day Direct Lithium Extraction ("DLE") pilot plant in our Calgary facility where the Company intends to prove the commerciality and effectiveness of our licensed DLE at a large scale."

The LithiumBank DLE pilot facility in Calgary was inaugurated on July 10, 2024 and has since initiated DLE pilot test work with lithium-rich brine from our flagship Boardwalk Lithium Brine Project, located ~50 kilometres north of Park Place. The Company expects to process this Park Place bulk brine sample in 2024.

While in the field the Company adhered to strict Quality Control and Quality Assurance ("QA/QC") protocols. Smaller, one litre, brine samples (6 litres in total) were collected at different locations of the collection stream including before and after oil, gas, and brine separation, before and after brine de-gassing. The sampling was overseen by Mr. Maurice Shevalier, P.Chem, of Matrix Solutions Inc., a Qualified Person ("QP") under National Instrument ("NI") 43-101 regulations. The Company delivered the 1L brine samples to AGAT Laboratories and to Bureau Veritas in Calgary Alberta. The batch of samples included duplicates, blanks, and control samples with known chemistry.

The field bulk sampling program was completed on July 4, 2024 and included collecting 148 m3 of brine from the top 72m of the Leduc formation. The brine passed through an industry standard triple phase separation of oil, gas, and brine from the well as the well is an active gas producer. The brine was then de-gassed using a mechanical separations method, provided by AMGAS. The brine was then transported and stored in Calgary Alberta where LithiumBank has its DLE facility.
