Mergers & Acquisitions Partnerships & JV

FRONTIER LITHIUM AND MITSUBISHI

CORPORATION COMPLETE JOINT VENTURE

TRANSACTION

SUDBURY, ON

,

April 25, 2024

/CNW/ - Frontier Lithium Inc. (TSXV: FL) (FRA: HL2) (OTCQX:

LITOF) ("Frontier" or "the Company"), is pleased to announce the successful closing of Tranche 1 of

the joint venture partnership with Mitsubishi Corporation ("Mitsubishi") (Tokyo Stock Exchange:

8058:JP). This joint venture for the PAK Lithium Project ("Project") marks a significant milestone in

advancing the first fully integrated lithium mining and processing operation in

Ontario, Canada

.

Through the joint venture partnership, as initially announced on

March 4, 2024

, Mitsubishi has

acquired an initial 7.5% interest in the Project for CAD

$25 million

. This strategic investment

underscores the confidence in the size, quality, and strategic importance of the Project to the North

American EV supply chain.

Frontier plans to utilize the funding from Mitsubishi to progress the Project towards a vertically

integrated Definitive Feasibility Study (DFS), which is expected to be completed in 2025.

Trevor Walker

, President, and CEO of Frontier Lithium emphasized the significance of the milestone

achieved today as the company advances its mission to become a leading lithium supplier within the

North American EV battery materials supply chain. "Mitsubishi's investment underscores their trust in

Ontario's

jurisdiction, as well as the caliber and scale of the PAK Lithium Project" stated

Trevor

Walker

. "We warmly welcome Mitsubishi and are honored to have a strategic, and reliable partner

enabling us to focus on generating long-term value for shareholders, communities, and all

stakeholders."

Transaction Details

The joint venture is structured to facilitate the majority of equity funding for the planned mine and mill,

with Frontier being able to reduce its share of development costs for the whole project, while

maintaining at least 75% of future off-take optionality. This partnership aligns with the recent

Memorandum of Cooperation signed between the governments of

Canada

and

Japan

to encourage

value-added investments that will help establish sustainable and reliable battery supply chains

between our two countries.

Key points of the joint venture transaction:

Frontier has contributed all assets pertaining to the Project in exchange for a 92.5% stake in the

JV and has assumed the role of JV manager.

Following the completion of the DFS, Mitsubishi will have the option to increase its interest in the

JV up to a 25% interest at a valuation based upon, among other things, the net asset value of

the Project outlined in the DFS ("Tranche 2").

Mitsubishi will collaborate closely with Frontier in securing debt financing to ensure full funding

for the Project's production.

The completion of Tranche 2 investment is contingent upon certain preconditions, such as

obtaining material infrastructure permits and other customary approvals. Frontier expects these

conditions to be met in 2025.
