VANCOUVER, British Columbia, June 16, 2025 (GLOBE NEWSWIRE) -- South Star Battery Metals Corp. ('South Star' or the 'Company') (TSXV: STS) (OTCQB: STSBF), is pleased to announce that it was selected by the R$5B (US$895M) Transformation of Strategic Minerals initiative sponsored by the BNDES and FINEP. The initiative targets increased production and transformation of minerals crucial for energy transition and decarbonization, focusing on developing supply chains for graphite, lithium, rare earth elements, and other strategic minerals in Brazil. The initiative is designed to accelerate the production and transformation of critical minerals essential for the global energy transition and decarbonization, with a strategic focus on building supply chains for priority resources.
South Star presented a work program and conceptual business plan for Santa Cruz Phase 2 and 3 expansions as well as the downstream transformation of graphite in Brazil for industrial and energy transition sectors. The Company will now submit a comprehensive business plan detailing market analysis, management, milestones, budgets, marketing strategy, operations plan, partnerships and socio-environmental impacts for increasing production with a phased, modular approach. South Star will work in partnership with BNDES and FINEP to assess the most appropriate potential financial structures for future funding, which could include credit facilities, equity participation, and grants to invest in productive capacity, research, development, and innovation ('RD&I').
In addition, the Company is pleased to announce that the maiden shipment of graphite concentrates from Santa Cruz left the mine on June 5th, 2025 and is enroute to North America. This significant milestone marks the transition of South Star into commercial production and underscores its commitment to establishing a reliable, scalable global supply chain with integrated graphite production in the Americas. Santa Cruz Phase 1 is the first new graphite production in the Americas since 1996 and is fully licensed and permitted through Phases 2 and 3, enabling total production capacity of up to 50,000 tonnes per year ('tpy') of high-quality Brazilian graphite concentrates. The next orders are being produced and are planned to ship shortly.
Richard Pearce, CEO of South Star, commented, "We are honored to be selected for this landmark strategic minerals initiative in Brazil. We are also proud of delivering the first new graphite production in the Americas since 1996 at a time when global supply chains have few options and political tensions are increasing. As a leading global producer of critical minerals, Brazil plays a pivotal role in supplying the metals essential for defense, industrial, energy transition, and stationary storage applications. Among Western jurisdictions, Brazil holds the greatest potential to rapidly scale production and drive innovation across the entire value chain—from raw materials to advanced manufacturing—supported by a skilled workforce, robust industrial base, clean energy and excellent infrastructure. Our selection is a strong endorsement of graphite's growing strategic importance, as well as of our long-term vision and commitment to supporting Brazil, our local communities, and our global clients. This support could be transformational for the expansion of our Santa Cruz operations and a key step toward unlocking long-term value for all stakeholders.'
Operational Update
As of the end of May 2025, South Star has achieved 916 days and 404,777 man-hours without a lost-time incident, which covers the entire construction, commissioning, and ramp-up phases of the Santa Cruz operation. The mine is performing well, and average grade and strip ratios are reconciling closely with the mine plan. There are approximately 35,000 tonnes of ore stockpiled on the run of mine ore ('ROM') pad.
The ramp-up process is ongoing and focused on achieving the following performance goals:
Complete construction and commissioning - (Achieved)
Plant mechanical availability of 92% - (Achieved)
Concentrates grade of 93-96 % graphitic carbon, ('Cg') - (Achieved)
Recoveries of approximately 82-84% - (On-going)
Constant Throughput of 30 tph of ore - (On-going)
Cost reductions initiatives - (On-going)
Santa Cruz has experienced several operational challenges during ramp-up:
Extreme rainfall and high winds in April and May (2.5x normal average), which significantly impacted production.
3 Pieces of major equipment are performing below the design performance specification for 450/500 tpm of production
High frequency screen
Entrance to rod mill
Tailings filter press
The performance bottlenecks are being reviewed by the South Star team and the equipment manufacturers. Active steps are being taken to resolve the issues quickly. In addition, the team is working through a thorough evaluation of the metallurgical mass and water balance and working to achieve a steady-state throughput to improve recoveries. All relevant factors including pulp densities, reagents dosing, ball size, mill RPMs and residence times are being optimized to improve recoveries and grade while maintaining the flake size. The Company is working diligently to resolve bottlenecks, evaluate new suppliers and equipment manufacturers to ensure qualified suppliers that can provide robust alternatives for maintenance and wear parts. The team is working to improve the preventative maintenance plans and minimum inventories to ensure efficient operations.
In addition, the Company is pleased to announce that Mr. Rogerio Barcellos Leite has been appointed as the Santa Cruz Director of Operations. A chemical engineer with a broad industrial and mining background, Mr. Barcellos Leite will lead process optimization, data-driven performance improvements, and the development of systems that drive operational clarity and culture.
Richard Pearce, CEO of South Star, commented, "We are pleased to welcome Rogerio to the team and look forward to working closely with him to clear bottlenecks and scale operations quickly at Santa Cruz. He has over 20 years of experience in mining and industry, with a proven track record of delivering operational excellence, a culture of continuous improvement, safety leadership, and sustainable growth across a range of commodities. As we stabilize and scale production at Santa Cruz to advance the strategic initiatives, Rogerio's expertise in operational strategy, workforce development, and continuous improvement will be instrumental in driving performance.'
