The build continues on budget and on schedule, and we are very proud of our ongoing safety record. The team will continue to work hard and focus on our ongoing commitment to safe, responsible operations. Significant progress has been made on the concrete and foundation work, which should be substantially completed in next couple weeks. Equipment manufacturing is on schedule and should be largely wrapped up in next 6 weeks, with all major equipment delivered to the mine. The electrical and mechanical contractor is in the process of mobilizing. We are firmly on track to be commissioning Santa Cruz in November and starting commercial production by EOY 2023.

About South Star Battery Metals Corp

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 (> 30 tonnes) 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 fully funded for Phase 1, and the 12-month 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 Q4 2023. Phase 2 production (25,000 tpa) is partially funded and planned for 2026, while Phase 3 (50,000 tpa) 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 is a historic mine active during World Wars I & II. A NI43-101 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 indicates a traditional crush/grind/flotation concentration circuit that achieved grades of approximately 94-97% Cg with approximately 86% recoveries. 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.
