LithiumBank Engages Hatch to Test Boardwalk Lithium Brine With 2 Direct Lithium Extraction Technologies Companies

LithiumBank Resources Corp. ( TSX-V: LBNK ) (" LithiumBank " or the " Company ") is pleased to announce the commencement of Direct Lithium Extraction (DLE) mineral processing test work on brines from the Company's Boardwalk Project, located 80 km east of Grande Prairie, AB. LithiumBank has engaged Hatch to assess leading DLE technologies in parallel from the shortlisted DLE technology companies to inform a Preliminary Economic Assessment and subsequent commercial plant design.

Highlights

• Hatch retained to design, test and manage all DLE programs for LithiumBank;
• Selected DLE technologies for testing using Boardwalk brine is underway; and
• Results are expected to be used as inputs to the process design of a facility to treat raw brine and produce battery grade lithium chemical product in the NI 43-101 Preliminary Economic Assessment (PEA).
  

Hatch is an engineering firm that has expertise in engineering, procurement, and construction management (EPCM) of lithium processing plants. LithiumBank's management team is working with senior members of Hatch's lithium group, with recent DLE project experience, to assess DLE technology options for the Boardwalk project. The results of the technology assessment performed by Hatch are expected be used in preparing a NI 43-101 Preliminary Economic Assessment (PEA) in respect of the Boardwalk Project. This PEA is a key steppingstone towards the design of a commercial facility that the Company anticipates will produce battery grade lithium chemical product.

LithiumBank first engaged Hatch in August 2021 to conduct a comparative study of multiple North American based DLE technologies that could deliver a high purity Lithium Chloride (LiCl) concentrate to be used in commercial, battery grade lithium chemical production from the Boardwalk brine. After an iterative process by Hatch, LithiumBank has narrowed the potential technology providers. The shortlisted companies have received brine from Boardwalk and have commenced test work to determine the key design parameters (e.g. selectivity of the lithium extraction media, extraction kinetics, and media longevity). This level of detail in the test work will provide the necessary information to inform preliminary economics around a lithium processing facility on site at Boardwalk.

LithiumBank COO, Kevin Piepgrass states:

"We are very excited to have commenced testing our brine with two of the shortlisted DLE technology companies. Both shortlisted companies have developed DLE materials and extraction processes that the Company believes have an ideal set of ranges of conditions required for peak performance. The temperature, pH, and chemistry at Boardwalk make these technologies ideal candidates and we look forward to receiving the results."

Brine used in the DLE test work was collected in August 2021 from well 100/09-26-068-22W5/00 located in the South Sturgeon Lake oilfield (see figure 1) and has a reported average grade of 73.8 mg/L Lithium (as previously reported in LithiumBank news release dated June 28, 2022).

The Boardwalk Leduc formation Li-brine inferred resource is globally estimated at 1,122,000 tonnes of elemental Li at an average lithium concentration of 67.1 mg/L Li in 16.7 km ³ of formation brine volume (Table 1). The global (total) lithium carbonate equivalent (LCE) for the inferred mineral resource is 5,973,000 tonnes LCE.

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.

Note

• Information derived from the Company's technical report entitled "NI 43-101 Technical Report, Inferred Resource Estimate on LithiumBank Resources Corp.'s Sturgeon Lake Lithium-Brine Property in West-Central Alberta, Canada" with an effective date of May 18, 2021
• 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.
• The weights are reported in metric tonnes (1,000 kg or 2,204.6 lbs).
• Tonnage numbers are rounded to the nearest 1,000 unit.
• In a ‘confined' aquifer (as reported herein), porosity is a proxy for specific yield.
• The resource estimation was completed and reported using a cut-off of 50 mg/L Li.
• In order 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).
