LithiumBank Resources Selected for Inclusion in the Canada Investment Summit Prospectus

LithiumBank Resources Selected for Inclusion

in the Canada Investment Summit Prospectus

Calgary, Alberta--(Newsfile Corp. - September 11, 2026) -

LithiumBank Resources Corp. (TSXV:

LBNK) (OTCQX: LBNKF) (FSE: HT9)

("

LithiumBank

" or the "

Company

") is pleased to announce

that its 100%-owned Boardwalk Lithium Brine Project, located in northwest Alberta, has been included in

the Canada Investment Summit Prospectus, highlighting Boardwalk as a project of strategic importance

and investment potential within Canada's emerging critical minerals sector.

The Canada Investment Summit (the "Summit") is being hosted by Canadian Prime Minister Mark

Carney, in partnership with the Canada Pension Plan Investment Board (CPP Investments) and the

Public Sector Pension Investment Board (PSP Investments), in Toronto, Ontario, on September 14 and

15, 2026. The Summit will bring together international institutional capital, strategic industry participants

and government partners with the objective of attracting up to $1 trillion of investment into Canada,

including investment into a select group of Canadian projects identified in the Prospectus. Boardwalk

hosts a significant lithium brine resource comprising 5.195 million tonnes of measured and indicated

lithium carbonate equivalent ("LCE") at an average lithium concentration of 81.6 mg/L, together with an

additional 2.777 million tonnes of inferred LCE at 79.0 mg/L, Boardwalk represents the highest-grade

measured and indicated lithium-brine resource reported in Alberta.

For LithiumBank, the inclusion of the Boardwalk Project provides an important validation of the project's

potential to become a significant domestic source of lithium and contribute to the development of

Canada's critical minerals and battery supply chain.

Boardwalk is a large-scale lithium brine project located in one of Canada's most established energy

jurisdictions. Its Alberta location provides access to extensive existing infrastructure, a sophisticated

energy-services ecosystem, transportation networks, technical expertise and a highly skilled workforce

— key advantages for the potential development of a major lithium operation.

Importantly, Boardwalk is positioned to leverage Alberta's existing oil and gas infrastructure and

expertise, providing the potential for a capital-efficient approach to lithium brine development compared

with greenfield projects requiring significant new infrastructure. The project's brine-hosted lithium

mineralization also provides the potential to utilize Direct Lithium Extraction (DLE) technologies, offering

a pathway toward efficient lithium recovery while minimizing the surface footprint associated with

conventional hard-rock mining.

"Inclusion in the Canada Investment Summit Prospectus acknowledges Boardwalk as one of the premier

projects in the country with the potential to make a significant contribution to Canada's critical minerals

strategy," commented Rob Shewchuk, CEO & Director. "The combination of our high-quality resource

and development Agreement with SLB, which includes binding DLE licensing terms, provides an

opportunity to develop an energy-efficient, cost-effective, and commercially viable end-to-end lithium

brine solution that can be constructed using a modular scale-up approach that leverages significant

existing infrastructure in a brownfield project with an environmentally responsible footprint to produce

lithium products that align with Canada's initiative to supply the global battery and energy ecosystem. We

are proud to represent Canada and Alberta's lithium at this event."

The Prospectus inclusion comes at an important time for LithiumBank as the Company advances

Boardwalk and continues to position the project for potential development and strategic investment.

Since May 2026 the Company has made significant progress advancing the development program

required to support commercial-scale design. Approximately 150,000 litres of Boardwalk brine have

been collected from the 10-6 well for process optimization and validation of the integrated flowsheet

under conditions representative of future commercial operations. The planned well-to-product

demonstration is designed to build on previous SLB pilot testing, which achieved lithium recoveries of up

to 95% and greater than 99% overall impurity rejection. The Feasibility Study is focused on the eastern

portion of Boardwalk, a well-characterized brownfield area with extensive historical oil and gas

infrastructure and data.

Additionally, in July 2026, LithiumBank signed a non-binding Letter of Intent ("LOI") to acquire an option

over existing wells, pipelines, related surface leases and easements associated with Boardwalk. The

infrastructure is expected to provide potential capital and timeline advantages by reducing the need to

construct new infrastructure for brine extraction and is being evaluated for incorporation into the

Feasibility Study.

In August 2026, the Company further advanced its infrastructure strategy by entering into a binding

option agreement to acquire up to 160 acres of privately owned land in the Sturgeon Lake area as a

potential site for Boardwalk's planned central processing facility. The site is located approximately 800

metres from Highway 43 and is served by a 138-kilovolt power transmission line, with an active natural

gas pipeline traversing the southern portion of the property.

The Company believes that recognition through the Canada Investment Summit further enhances

Boardwalk's visibility among institutional investors, strategic partners and potential sources of project

capital, while underscoring the broader strategic value of developing a domestic Canadian lithium supply

chain.

About LithiumBank Resources Corp.

LithiumBank Resources Corp. (TSXV: LBNK) (OTCQX: LBNKF) is a publicly traded lithium company

that is focused on developing its two flagship projects, Boardwalk and Park Place, in Western Canada.

These projects host some of the largest lithium brine resources in North America. The Company holds

1,240,140 acres of brown-field brine hosted mineral licenses across three districts in Alberta and

Saskatchewan. The Company has pilot tested multiple mature Direct Lithium Extraction ("DLE")

technologies and has signed a Development Agreement with SLB to bring the Boardwalk project into

production. This agreement includes binding DLE licensing terms with SLB to provide an energy

efficient, cost-effective and commercially viable end-to-end lithium brine solution. The Company is now

working toward establishing commercial lithium production by leveraging existing brownfield

infrastructure and a modular scale-up approach.
