South Star Battery Metals

What South Star Battery Metals does

South Star Battery Metals Corp. is a Canadian junior mining company headquartered in Vancouver and publicly listed on the TSX Venture Exchange (STS) and OTCQB (STSBF). It is focused on the exploration, development, and production of graphite concentrate for electric vehicle battery manufacturers and broader clean-energy and industrial end-markets. The company holds a 75% interest in the Santa Cruz Graphite Mine in Bahia, Brazil — located in the Araçuaí Orogen graphite belt and within one of the world's top-three graphite exporting jurisdictions — and a 75% interest in the Alabama Graphite Project (BamaStar) in the United States.

Its core product is a high-purity graphite concentrate grading up to 97% total carbon, produced via a conventional crushing, milling, and flotation circuit. The Santa Cruz facility is engineered for an initial 5,000-tonnes-per-annum nameplate capacity with a stated expansion target of 10,000 tonnes per annum. The company reports 60-65% reductions in processing costs versus historical levels, positioning it as a low-cost mid-scale producer relative to larger greenfield projects in the sector.

South Star is in active commercial ramp-up. The processing plant was restarted three months ahead of schedule in April 2026, with the first commercial concentrate shipment completed in July 2026 and an initial purchase order milestone reached in August 2026. The company has historically reported negligible revenue, has raised over C$13 million across multiple private placements between 2022 and 2026, employs 11-50 staff, and is led by CEO Tiago Cunha (appointed 2024), who controls approximately 38.23% of outstanding shares. COO Rogério Barcellos oversees Brazilian operations.
