VANCOUVER, July 29, 2024 - Highlights:

• Mine prestrip, preliminary dump foundations and ramps are complete, and approximately 50,000 tonnes of ore is being placed on the ore pad by end of August for commissioning and initial operations.

• The following plant areas are substantially complete, and commissioning of the equipment is underway:

  • Primary and secondary crushing circuit

  • Floatation/grinding/screening plant

  • Tailings thickener and filter press facilities

  • Concentrate dewatering, drying, screening and bagging systems

• Internal power distribution, laboratory, support services and other appurtenant installations are substantially complete and ready for operations.

• The mainline powerline is substantially complete, and the regional energy company COELBA is scheduling the installation of the energy meter and final connection of the installations to the grid power.

• Commissioning is expected to take approximately 6-7 weeks, after which the plant should be ready for ramp-up and start of commercial production.

VANCOUVER, July 29, 2024 - South Star Battery Metals Corp. ("South Star" or the "Company") (TSXV:STS)(OTCQB:STSBF) is pleased to announce that Phase 1 construction for the Company's flagship Santa Cruz Graphite Mine ("Santa Cruz") is substantially complete and commissioning is underway. Santa Cruz is located in Bahia, Brazil, and the Phase 1 plant has a nameplate capacity of approximately 12,000 tonnes/year ("tpy") of natural flake graphite concentrates. Santa Cruz is scheduled to commission the Phase 1 plant and to start commercial production in September 2024. South Star plans to fulfill initial graphite purchase orders in Q4 2024.

The infill drilling and short-term mine plan/sequence for the first quarters of the mine sequence are complete. Prestrip is finalized and approximately 50,000 tonnes of ore will be placed on the ore pad in August 2024. The mine plan confirms simple, open pit mining of oxide ore with at-surface mineralization and a low 6-month strip ratio of approximately 0.5(W):1(O).

Commissioning is underway and is expected to take approximately 6-7 weeks for the four main plant areas:

1. Crushing circuit - approximately 7-10 days commissioning schedule;

2. Floatation/grinding/screening plant - Approximately 6 -7 weeks commissioning schedule;

3. Tailings thickener and filter press - Approximately 4 weeks commissioning schedule; and

4. Concentrate dewatering, drying, screening and bagging systems - Approximately 4 weeks commissioning schedule.

South Star President and CEO Richard Pearce commented, "We are pleased to have achieved this important milestone of substantial completion of the Phase 1 construction and continue advancing towards ramp-up and commercial production. We have commercial agreements for large-scale industrial samples in place and look forward to shipping those samples in early in Q4 2024. Our Phase 1 production schedule of 12,000 tpy of natural flake graphite will make us the second largest natural flake graphite producer in the Americas. Our team is delivering on our promise to be the first new graphite production in the Americas since 1996."

South Star's immediate go-to-market commercial strategy is to produce high-quality graphite concentrates for various 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 -- 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 -- with commercial sales planned for Q4 2026. The Company looks forward to updating the market on the progress of developments with other potential customers as soon as details are finalized.

About South Star Battery Metals Corp.

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 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, Alabama and a downstream value-add plant in the Southeast USA, 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.
