Lithium Ionic Engages RTEK to Support Construction and Operational Readiness

of Bandeira Project; Announces Leadership Transition to Strengthen Project

Execution

TORONTO, ON, April 2, 2025 – Lithium Ionic Corp. (TSXV: LTH; OTCQB: LTHCF; FSE: H3N)

(“Lithium Ionic” or the “Company”) is pleased to announce that pursuant to a services agreement

signed April 2, 2025 (the “RTEK Agreement”), it has engaged RTEK International DMCC (“RTEK”)

as a strategic advisor to fast -track the development of its flagship Bandeira Lithium Project

(“Bandeira” or the “Project”) in Brazil’s prolific Lithium Valley. This long-term partnership integrates

world-class lithium expertise into Lithium Ionic’s owner’s team as the Project transitions from

feasibility to construction and operations.

RTEK is recognized globally for its technical and operational expertise in the lithium sector . The

team has over 80 years of combined lithium experience in chemical and metallurgical operations,

process development, geology and project execution. Their track record of accelerating project

timelines, reducing capital intensity, and launching successful lithium operations globally, will be

instrumental in unlocking the full value of the Bandeira Project.

Blake Hylands, P.Geo., CEO of Lithium Ionic, commented, “We are thrilled to welcome RTEK’s

deeply experienced team to support Bandeira’s next phase of growth. Their lithium -specific

expertise, paired with a history of delivering high -performance operations, aligns perfectly with

our vision for Bandeira. With construction approaching, RTEK’s involvement strengthens our

execution capabilities and brings valuable insight from proven success in Brazil’s Lithium Valley.”

RTEK is led by a globally recognized team of lithium industry veterans , including Brian Talbot,

Nicholas Rowley, Noel O’Brien, and Rodrigo Roso, who have delivered results across the full

mine lifecycle, from feasibility through to production. As part of the owner’s team, RTEK will

conduct a detailed review of Lithium Ionic’s NI 43-101 Feasibility Study, identifying opportunities

to optimize plant and mine design, reduce CAPEX and OPEX, and explore strategies to compress

the development timeline , ultimately position ing Bandeira as one of Brazil’s next high- impact

lithium producers.

Beyond engineering management and construction planning, RTEK will also develop a

comprehensive operational strategy. This includes optimizing processes, managing

commissioning, and overseeing ramp-up activities to ensure best -in-class production

performance.

Brian Talbot, Founder and Director of RTEK, commented, “We’re excited to join forces with

Lithium Ionic at such a pivotal moment in the development of the Bandeira Project. With a strong

foundation already in place, we see excellent potential to accelerate the advancement of this

project to production by applying proven strategies in design optimization, cost efficiency, and

execution discipline. Bandeira has all the hallmarks of a globally competitive lithium operation,

and we look forward to helping unlock that value as part of the owner’s team.”

Mr. Talbot is a seasoned lithium executive with extensive operational experience leading some of

the world’s most prominent hard rock lithium operations. He previously served as Chief Operating

Officer of Sigma Lithium (NASDAQ: SGML; TSX: SGML), where he successfully transitioned the

Grota do Cirilo Project in Brazil from construction to production. At Galaxy Resources (now

Arcadium Lithium; NYSE: ALTM; ASX: ALTM), he played a key role in doubling output at the Mt.

Cattlin mine in Australia and driving operational improvements. His deep expertise in dense media

separation (DMS) technology, process optimization, and mine development has consistently

delivered strong results, making him instrumental in positioning Bandeira as a future leading

lithium producer.

Mr. Rowley brings over 16 years of experience in strategic M&A, equity financings and commodity

trading, with a strong focus on building supply chains to Asia, particularly for lithium ore sourced

from Australia, South America, and Africa. During his tenure at Galaxy Resources (now Arcadium

Lithium), he played a pivotal role in M&A, leading the Corporate Development team in forging

strategic partnerships, securing offtake agreements, and managing asset divestitures. His efforts

were instrumental in facilitating the US$4 billion merger with Orocobre Limited, creating one of

the world’s leading lithium producers globally.

Mr. O’Brien is a seasoned metallurgist with over 40 years of global experience in lithium

processing, project development, and operations. He has held senior technical and advisory roles

across numerous high- profile lithium projects, including Mt. Holland (Wesfarmers), Goulamina

(formerly owned by Birimian Ltd .), Galaxy Resources (now Arcadium Lithium), and Bikita

Minerals. Known for his expertise in flowsheet design, cost -effective processing solutions, and

project execution, he has successfully advanced projects from concept to commissioning. His

extensive experience will be key to optimizing Bandeira’s design and ensuring efficient

operational readiness.

Mr. Roso is a mining executive and corporate lawyer with over 20 years of experience in project

development, corporate finance, and M&A. Throughout his career, Rodrigo has played a pivotal

role in the execution of projects exceeding $35 billion in CAPEX, contributing to the growth and

success of major mining enterprises, with involvement at companies such as Sigma Lithium, Vale,

Mosaic, Largo Resources, and Yamana. His broad experience spans both in- house leadership

and advisory roles, giving him a strong c ommand of legal, regulatory, and strategic frameworks

critical to advancing mining assets. His strategic insight and deep industry knowledge will be

instrumental in supporting the successful development and execution of the Bandeira Project.

About the RTEK Agreement

Pursuant to the RTEK Agreement , RTEK consultants will be integrated with Lithium Ionic’s

owner’s team to drive the advancement of the Bandeira Project. Their mandate includes

progressing detailed engineering, optimizing the operational design, and identifying opportunities

to reduce CAPEX and OPEX to ensure cost-efficiencies and prepare the Project for construction

readiness (the “Services”).

Unless terminated pursuant to the terms therein, the RTEK Agreement shall continue until the

completion of the Services. As consideration for the Services, (i) Lithium Ionic and RTEK shall

agree on an operational budget which shall be paid in cash; and (ii) if RTEK achieves certain

operational milestones (the “Milestones”), including the reduction in Project CAPEX, Project

implementation and commissioning of a dense media separation plan for the Project, RTEK shall

be entitled to compensation in Lithium Ionic common shares (the “Share Compensation”). The

Share Compensation will only be issued following the completion of the applicable Milestone and

the price per Lithium Ionic share shall be determined after the Milestone has been completed.

The RTEK Agreement and all Share Compensation is subject to TSX Venture Exchange

approval. All LTH common shares issued in connection with the RTEK Agreement will be subject

to a statutory hold period of four‐months and a day in accordance with applicable Canadian

Securities Laws.

The Bandeira Project has rapidly established itself as one of the fastest growing and most

promising lithium assets in Brazil’s Lithium Valley, with a robust feasibility study outlining strong

economics, bottom-quartile operating costs, and a near-term path to production. The engagement

of RTEK reinforces Lithium Ionic’s commitment to leveraging world-class expertise as it transitions

from feasibility into construction on its path towards becoming Brazil’s next major lithium producer.

Leadership Transition to Support Next Phase of Project Development

Lithium Ionic also announces a change in its senior management team. Mike Westendorf, who

joined the Company in February 2024 as Vice President, Technical Services, has been appointed

Chief Operating Officer (COO), replacing Paulo Misk. Mr. Westendorf has over two decades of

operational and technical experience in the mining industry, including leadership roles at Copper

Mountain Mining Corp., where he oversaw production, capital projects, and technical

performance. Since joining Lithium Ionic, he has play ed a key role in advancing the Bandeira

Project, including his significant contributions to the Feasibility Study released in May 2024. The

Company thanks Mr. Misk for his contributions and wishes him all the best in his future

endeavours.
