South Star Battery Metals Announces Proposed Joint Venture with Graphex

Technologies, LLC to Develop a Manufacturing and Processing Facility for

Battery Anode Material

The joint venture will allow for a centrally located, vertically integrated supply chain for active battery anode

material supplied by two high-quality, scalable graphite operations in two strategic and stable jurisdictions in the

Americas

VANCOUVER, British Columbia, June 07, 2022 -- South Star Battery Metals Corp. (“South Star” or the “Company”) (TSXV:

STS) (OTCQB: STSBF), is pleased to announce the signing of a Letter of Intent (“LOI”) with Graphex Technologies, LLC

(“Graphex”) to jointly develop a manufacturing and processing facility for battery anode material. The parties intend to develop a

definitive agreement by October 31, 2022 to share expertise and technology for the design, construction and operations of a

battery anode material processing facility. Graphite feed stock is expected to be provided by South Star’s Santa Cruz Graphite

Mine in Brazil and Ceylon Graphite Mine in the United States. The goals of the joint venture are to have a centrally located,

vertically integrated supply chain for active battery anode and value-added materials supplied by two high-quality, scalable

graphite operations in two strategic and stable jurisdictions in the Americas. The Companies previously announced a LOI to

pursue a binding 5-year offtake agreement (March 24th, 2022)

Richard Pearce, CEO of South Star, said, “We are breaking ground on Santa Cruz Graphite Mine in June, 2022 and have

commercial production planned for Q2 of 2023. The Ceylon Project in Alabama is advancing well, and we are starting

metallurgy and battery testing programs. We are pleased to be further developing a long-term, strategic relationship with

Graphex at a critical moment in the energy transition revolution. Graphex has been producing and selling high-quality battery

anode material for a long time, and similar to us, looking to expand operations in the US. South Star believes that the only

way to meet the growing demand is for experienced companies to develop strategic partnerships that accelerate the vertically

integrated production of high-quality products that can be consistently delivered in a responsible and profitable manner. This

partnership will benefit both parties and allow us to quickly deliver critical battery anode and other value add materials for

clients in strategic locations around the world. Reliable, secure supply chains are the key to the world’s ability to execute on

the exciting energy transition revolution underway, and South Star is pleased to be part of this paradigm shift.”

John DeMaio, CEO of Graphex Technologies said, “We look forward to collaborating with South Star to explore the exciting

prospects of diversifying the upstream supply of graphite to the global EV ecosystem. The volume, quality, and stability of

supply from their assets in Brazil and the U.S. coupled with our proven expertise in delivering high-volume, high-quality anode

material would have significant positive impact on the industry’s ability to meet production projections for EVs in the coming

years and decades.”

South Star Battery Metals Corp. is a Canadian battery metals project developer focused on the selective acquisition and

development of near-term production projects in the Americas. South Star’s Santa Cruz Graphite Project, located in Southern

Bahia, Brazil is the first of a series of industrial and battery metals projects that will be put into production. Brazil is the

second-largest graphite-producing region in the world with more than 80 years of continuous mining. Santa Cruz has at-surface

mineralization in friable materials, and successful large-scale pilot-plant testing (>30t) has been completed. The results of the

testing show that approximately 65% of Cg concentrate is +80 mesh with good recoveries and 95%-99% Cg. With excellent

infrastructure and logistics, South Star is carrying its development plan towards Phase 1 production projected in Q2 2023.

South Star’s next project in the development pipeline is a project in Alabama located in the middle of a developing electric

vehicle, aerospace and defence hub in the southeastern United States. The Project is a historic mine active during World

Wars I & II. Trenching, sampling, analysis, and preliminary metallurgic testing has been completed. The testing indicated a

traditional crush/grind/flotation concentration circuit achieved grades of approximately 96-97% with approximately 86%

recoveries. and South Star is executing on its plan to create a multi-asset, diversified battery metals company with near-term

operations in strategic jurisdictions. South Star trades on the TSX Venture Exchange under the symbol STS, and on the

OTCQB under the symbol STSBF.
