South Star Battery Metals Announces Approval of All Final Exploration Reports of Santa Cruz Mine by Brazilian Mining Authority

The approval of the Final Exploration Reports for all 13 claims totaling approximately 13,000 hectares is presented in Table 1. The other 7 claims had the final exploration reports previously approved on February 8^th, 2022 (See February 9^th, 2022 Press Release).

"All 13 final exploration reports for the Santa Cruz Graphite Project have been approved by the ANM. We have a large land package with approximately 13,000 hectares in one of the most prospective graphite producing regions in the world. The markets understand Brazilian graphite, like Brazilian graphite and are looking for more Brazilian graphite. The USGS Mineral Commodities Summary for 2022 lists Brazil as having the third largest reserves of graphite in the world (70,000,000t) behind Turkey and China, and the second largest producer of graphite in 2021 (68,000t) behind only China. South Star has just increased Brazil's total by 17% with reported 43-101 reserve estimates of 12.3Mt and a 12-year mine life, and the combined total of our ANM compliant resource estimates in the 13 Final Exploration Reports total over 40Mt," commented Richard Pearce, President and CEO of South Star. "This is a scalable, high-quality, world-class deposit that is just getting started, and South Star will be the first new graphite production in the Americas in more than a decade. 2022 and 2023 will be transformative for South Star. Once again I'd like to thank our team and the analysts at the ANM for all their hard work and dedication."

PRODUCT INFORMATION BULLETINS FOR PHASE 1 OPERATIONS

The Company is pleased to launch the Product Information Bulletins (PIBs) for natural flake, crystalline graphite concentrate products for the Santa Cruz Phase 1 Operations. Flake size distributions vary from very fines (ASTM -325 mesh or 44 microns) to large flake (ASTM +30 mesh or 600 microns) and carbon grade ranging from 87% to 96%. The PIBs present the physical and chemical characteristics of a range of products, and the Company is in ongoing commercial talks for the sale of 100% of the Phase 1 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 Q1 2023, pending financing.

South Star's next project in the pipeline is a development 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 it's plan to create a multi-asset, diversified battery metals company with near-term operations in strategic jurisdictions.
