Calgary, Alberta--(Newsfile Corp. - May 16, 2024) - LithiumBank Resources Corp. (TSXV: LBNK) (OTCQX: LBNKF) ("LithiumBank'' or the "Company") is pleased to announce the acquisition of a wellbore within its 100%-owned Boardwalk Lithium Brine Project located in west-central Alberta, Canada.

The Alberta Energy Regulator (AER) approved the transfer of 100% ownership of well ID: 100/10-06-069-21W5/00 ("10-6"), along with surface rights and road access from the previous owner/operator to LithiumBank. The 10-6 well is a past producing oil and gas well, and since 2005, has produced hydrocarbons and brine from the Sturgeon Lake South oil field at the top of the Leduc Formation ("Fm"). 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. The Production Zone hosts Boardwalk's Indicated 395,000 tonnes LCE resource at 71.6 mg/L lithium with 5.734 million tonnes LCE at 68.0 mg/L Li Inferred. Acquisition of the 10-6 well will allow LithiumBank to access brine as required for Direct Lithium Extraction testing in our 10,000 litre/day pilot plant and confirm the continuity of the lithium brine reservoir. The Company intends to deepen the well and test the lower Leduc intervals in the coming months.

Within the boundary of the Boardwalk project, the Leduc reef has a thickness of approximately 230 to 380 m (average and maximum thicknesses of 206 m and 408 m) along a southwest to northeast cross section (Hydrogeological Consultants Ltd., 2012). See Figures 2 & 3. It hosts ~17 km³ of lithium-rich brine that may produce 34,005 t LHM per year in the development scenario envisioned in the Company's January 2024 PEA. LHM, or Lithium Hydroxide Monohydrate is a commercial-grade product that may be used in a variety of battery cell applications.

Table 1: Boardwalk Project 2024 Resource Estimates

Note 1: Mineral resources are not mineral reserves and do not have demonstrated economic viability.
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), porosity is a proxy for specific yield.
Note 5: The resource estimation was completed and reported using a cutoff 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).

LithiumBank previously sampled the 10-06 well in 2021 along with three other wells in the area that averaged 71.8 mg/L lithium across. The well was drilled in 2005 and produced crude oil before elevated brine levels lead to its suspension. The original operator drilled approximately 168 meters into the Leduc formation which is estimated to be over 200 meters thick in this area. LithiumBank plans to re-enter the well and drill through to the lower portions of the Leduc Formation.

"We are very excited to receive our permit from the AER to drill our first well at Boardwalk" comments LithiumBank CEO Rob Shewchuk. "We expect the results of this drilling to upgrade the confidence of our resource at Boardwalk as a competitive lithium resource in North America".

LithiumBank is also pleased to announce that is has engaged McElhanney to provide engineering and regulatory expertise. McElhanney will provide guidance to LithiumBank with regard to further acquisition of wells where brine can be acquired and stored for future pilot tests.

The current Boardwalk Resource Estimate of 395,000 t LCE Indicated at 71.6 mg/L Li and 5,734,000 t LCE Inferred at 68.0 mg/L Li is NI 43-101 compliant, dated effective February 22, 2024, entitled "Preliminary Economic Assessment (PEA) for LithiumBank Resources Boardwalk Lithium-Brine Project in West-Central Alberta, Canada". The PEA was prepared by the following Qualified Persons: Roy Eccles, P. Geol. of APEX Geoscience Ltd., Kim Mohler, P. Eng. of GLJ Ltd., Gordon MacMillan, P. Geol. of Fluid Domains, Jim Touw, P. Geol. of HCL Ltd., Frederick Scott, P. Eng. of Scott Energy Inc., Egon Linton, P. Eng. of Hatch Ltd., Evan Jones, P. Eng. of Hatch Ltd., Stefan Hlouschko, P. Eng. of Hatch Ltd., and Lisa Park, AusIMM.

The indicated and inferred Boardwalk Leduc Formation lithium-brine resource estimations are presented as a total (or global value), and were estimated using the following relation in consideration of the Leduc Formation aquifer brine:

Lithium Resource = Total Brine Aquifer Volume X Average Porosity X Percentage of Brine in the Pore Space X Average Concentration of Lithium in the Brine.

The PEA disclosed in this news release is preliminary in nature as it includes a portion of Inferred mineral resources that are considered too speculative geologically to have the economic considerations applied to them that would enable them to be categorized as mineral reserves. There is no certainty that the results of the PEA will be realized. 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 be converted into a mineral reserve. The estimate of mineral resources may be materially affected by geology, environment, permitting, legal, title, taxation, socio-political, marketing, or other relevant issues.
