Highlights:

• BamaStar natural flake graphite concentrate was successfully upgraded to 99.95% fixed carbon, which is suitable for lithium-ion batteries and a variety of other value-add applications.

• South Star is advancing a process flowsheet for producing coated, spheronized, purified graphite ("CSPG") using commercially available equipment and industry standard, proven technology with no special products or proprietary intellectual property.

• The purification test results will be incorporated into the upcoming National Instrument 43-101 Preliminary Economic Assessment ("PEA"), which is scheduled for publication in September 2024.

• South Star's immediate go-to-market commercial strategy is to produce high-quality graphite concentrates from Santa Cruz Graphite Mine in Brazil beginning in 2024 for a variety of industrial applications and sectors. Concurrently, technical product-development programs are continuing to advance the Company's vertically integrated midstream and downstream product suite for value-added applications using graphite concentrates from both Santa Cruz and BamaStar, with commercial sales planned by Q4 2026.

VANCOUVER, BC / ACCESSWIRE / August 22, 2024 / SOUTH STAR BATTERY METALS CORP. ("South Star" or the "Company") (TSXV:STS)(OTCQB:STSBF) is pleased to announce the positive purification results using a classic chemical purification process with its technology partner, Dorfner Anzaplan GMBH ("Anzaplan"). Chemical purification is the proven industry standard, which is currently the primary scalable, commercially-viable technology in use for improving the quality of concentrate graphite for a broad range of value-add applications, including lithium-ion batteries ("LiB"). Further to the March 23, 2024 press release, the purification test results will be incorporated into the upcoming PEA, which is scheduled for publication in September 2024.

Multiple kilograms of run-of-mine, natural flake graphite concentrate from the BamaStar Graphite Project ("BamaStar") with an average fixed carbon content of 93.47%, were purified to 99.95% C at Anzaplan's laboratory in Hirschau, Germany. The excellent purification results prove the material can be upgraded to a purity that is suitable for a broad range of battery applications including, alkaline, lead-acid and LiB, as well as value-add applications such as conductivity enhancement materials, expandable/expanded graphite, brushes, foils and gaskets. Additionally, the initial tests are unoptimized and resulted in extremely pure graphitic carbon with low levels of contaminants, as well as ease and flexibility of upgrading using dilute reagents. Additional test work, studies and optimizations are ongoing.

Richard Pearce, President and CEO of South Star, commented: "We are pleased to announce these exciting purification results for BamaStar, as part of the upcoming PEA study. Both our projects have now proven their suitability to attain purified grades suitable for LiBs and other value-add applications. In multiple conversations with LiB battery manufacturers, they all emphasize a similar message for potential anode suppliers. They are looking for solid partners that have scalable projects in secure jurisdictions and can provide similar anode products to their current materials secured from Asia using simple, proven technologies and production flowsheets. They also want alternative production locations in the Americas and Europe to ensure a more secure, more diversified supply chain. South Star is proud of its accomplishments at Santa Cruz as the first new graphite producer in the Americas since 1996, with production planned for Q3 2024. Our team is executing the Company's strategic plan of bringing vertically integrated, phased/modular production in the Americas of midstream and downstream products in a disciplined, technically viable and profitable business plan with commercial sales planned by 2026."

South Star has a go-to-market commercial strategy to offer an extremely high-quality graphite concentrates from Santa Cruz in Brazil to a broad array of possible markets and sectors in 2024. Concurrently, technical product-development programs are continuing to advance the Company's vertically integrated midstream and downstream product suite for value-added applications -- specifically, battery-graphite products, including specialty Coated Spherical Purified Graphite ("CSPG" or "Active Anode Material") for lithium-ion ("Li-ion") battery applications and conductivity-enhancement products applicable to all commercial primary and secondary battery chemistries.

About South Star Battery Metals Corp.

South Star 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 (> 30 tonnes) has been completed. The results of the testing show that approximately 65% of graphite concentrate is +80 mesh with good recoveries and 95%-99% graphitic carbon (Cg). With excellent infrastructure and logistics, South Star is fully funded for Phase 1, and the construction and commissioning are underway. Santa Cruz will be the first new graphite production in the Americas since 1996, with Phase 1 commercial production projected in Q3 2024. Phase 2 production (25,000 tonnes / year) is partially funded and planned for 2026, while Phase 3 (50,000 tonnes / year) is scheduled for 2028.

South Star's second project in the development pipeline is strategically located in Alabama, U.S.A. in the center of a developing electric-vehicle, aerospace, and defense hub in the southeastern United States. The BamaStar Project includes a historic mine active during the First and Second World Wars. A NI 43-101 guided technical report with the maiden resource estimate has been filed on SEDAR. Trenching, Phase 1 drilling, sampling, analysis, and preliminary metallurgical testing have been completed. The testing included a traditional crush/grind/flotation concentration circuit that achieved grades of approximately 94-99% Cg with approximately 90% recoveries. The vertically integrated production facilities include a mine and industrial concentrator in Coosa County, AL and a downstream value-add plant in the Southeast U.S., which will be upgrading natural flake graphite concentrates from both Santa Cruz and BamaStar mines. 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.

South Star is committed to a corporate culture, project execution plan and safe operations that embrace the highest standards of ESG principles, based on transparency, stakeholder engagement, ongoing education, and stewardship.
