LithiumBank Advances Boardwalk Toward Commercial Production with SLB
LithiumBank Advances Boardwalk Toward
Commercial Production with SLB
Vancouver, British Columbia--(Newsfile Corp. - May 28, 2026) - LithiumBank Resources Corp. (TSXV:
LBNK) (OTCQX: LBNKF) ("LithiumBank" or the "Company") is pleased to announce the advancement
of its 100% owned Boardwalk lithium brine project ("Boardwalk") through the initiation of a Feasibility
Study and Front-End Engineering Design ("FEED"), awarded to global energy technology company and
NYSE listed SLB. Boardwalk is centrally located in northwest Alberta in close proximity to highways,
roads, pipeline infrastructure and grid power.
The Company completing such a milestone marks a significant step forward under LithiumBank's
previously announced Development Agreement with SLB. SLB will support this project using its
proprietary integrated lithium production solution, which includes systems for brine treatment, Direct
Lithium Extraction ("DLE") technology, impurity removal, brine concentration and lithium conversion
processes. SLB's process has been tested at one of the world's largest DLE-based demonstration
plants, in Clayton Valley, NV (
SLB link
).
The Feasibility Study will build directly on the robust technical and economic foundation established in
the Company's updated Preliminary Economic Assessment ("PEA") for Boardwalk, announced in 2024
(see
January 16, 2024
release for further details). The PEA highlighted the project's potential to be a
globally competitive lithium brine operation, demonstrating a pre-tax NPV (8%) of approximately US$3.7
billion and low operating costs of US$4,588 per tonne of lithium carbonate equivalent (LCE). These
results underscore the advantages of Boardwalk's scale, 100% crown land position, resource quality, no
overlapping carbon capture permits and favourable infrastructure setting in Alberta.
The upcoming Feasibility Study and FEED work will further refine these assumptions through detailed
engineering, integrated process design, and optimized development planning. Importantly, the study is
expected to evaluate and capture the potential benefits of leveraging existing oil and gas infrastructure
within the project area-an opportunity that was not incorporated into the PEA-which could further reduce
capital requirements and improve overall project economics. This next phase is expected to enhance
project definition, reduce execution risk, and position Boardwalk for a disciplined transition toward
commercial production.
The Feasibility and Front-End Engineering and Design ("
FEED
") study will evaluate an initial modular
development scenario consisting of two DLE units, each capable of producing up to 5,000 tonnes per
annum ("tpa") of lithium carbonate, for a total of up to 10,000 tpa. The modular design enables scalable,
phased expansion while reducing capital intensity and execution risk.
LithiumBank previously completed initial DLE pilot testing with SLB (see news release dated April 14,
2025), demonstrating sustained lithium recoveries of up to 95% and exceptional impurity removal, with
greater than 99% overall rejection. Individual impurity rejection rates included 98.80% for boron, 99.97%
for calcium, 99.96% for magnesium, 99.98% for potassium, 99.98% for sodium, and 99.97% for
strontium. The initial pilot campaign processed approximately 35,000 litres of brine sourced from the
Boardwalk project.
Building on these results, the upcoming well-to-product demonstration will process approximately
120,000 litres of Boardwalk brine from the Company's 10-6 well over a period of approximately three
weeks. This extended, continuous operation, is designed to support process optimization and inform
commercial-scale design and construction parameters.
"We are excited to advance Boardwalk supported by SLB, whose proven technology and global
execution capabilities from subsurface expertise through to lithium conversion provide a pathway to
commercial production which will enable the company to de-risk and accelerate our commercial
production journey, effectively bypassing the costly and time-consuming demonstration facility
processes. This collaboration will provide a pathway for the company to achieve the first commercial
scale brine production in Canada beyond 10,000 tpa LCE," commented Rob Shewchuk, CEO and
Director of LithiumBank.
The Company also acknowledges the strong and continued support of the Government of Alberta, which
has demonstrated a clear commitment to advancing innovative resource development and reducing
emissions through strategic funding initiatives. The $3.9 million in non-dilutive funding from Emissions
Reduction Alberta reflects the province's confidence in Direct Lithium Extraction technologies and the
potential for lithium brine projects such as Boardwalk to contribute to Alberta's evolving energy
landscape.
Alberta's established regulatory framework, extensive subsurface expertise, and proactive approach to
integrating emerging technologies position the province as a leading jurisdiction for lithium development
in North America. Government-backed programs like ERA play a critical role in accelerating project
timelines, de-risking early-stage development, and supporting the commercialization of lower-impact
extraction methods. LithiumBank believes this collaborative environment will be instrumental in
advancing Boardwalk toward production while contributing to Alberta's economic diversification and
participation in the global battery supply chain.
As part of this development program, LithiumBank has commenced Milestone 2 under its funding
agreement with Emissions Reduction Alberta ("ERA"), which provides up to $3.9 million in non-dilutive
funding.
Supporting this work, approximately 150,000 litres of brine have been collected from the Company's 10-
6 well within the study area. This material will be used to optimize processing parameters and validate
the integrated flowsheet under conditions representative of future commercial operations. Following DLE
extraction, the lithium-rich eluate will undergo further concentration via high-pressure reverse osmosis
system before final conversion into battery-grade lithium carbonate.
The Feasibility Study will focus on the eastern portion of the Boardwalk resource, a well-characterized
brownfield area with extensive historical oil and gas infrastructure and data. This area hosts measured
and indicated resources within LithiumBank's NI 43-101 estimate, which outlines 5.2 million tonnes
measured and indicated of lithium carbonate equivalent (LCE) and 2.8 million tonnes inferred LCE.
Boardwalk's NI 43-101 resource estimate, as outlined in the "LithiumBank Resources Corp. Boardwalk
NI 43-101 Technical Report" (effective February 20, 2025), includes Measured and Indicated resources
of 5.2 million tonnes of lithium carbonate equivalent ("LCE") at an average grade of 81.6 mg/L lithium
within 11.96 cubic kilometres of brine, and Inferred resources of 2.8 million tonnes LCE at 79 mg/L
lithium within 6.56 cubic kilometres of brine.

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).
This collaboration outlines a comprehensive development roadmap spanning feasibility, engineering,
procurement, construction, and commissioning, with a targeted path to commercial production as early
as 2029.
Boardwalk is positioned to become a strategically important domestic source of lithium, supporting the
growing North American electric vehicle and energy storage supply chains.
